Introduction

Pakistan is an Asian country located to thre west of India (of which it once belonged), overlooking the Arabian Sea to the south and crossed, in the far north, by very high mountains (Karakoram, Hindu Kush, and Pamir), which are part of the Himalayas, and to the west, on the border with Afghanistan, by mountains of a lower height.
In much of Pakistan, the climate is tropical or subtropical, semi-arid or desert, but in the north, the area af the foot of the mountains is is quite rainy, moreover, we find a cold area in the mountains and a frigid area on the peaks of the Himalayas.
In the cold half of the year, from late autumn to early spring, the north is reached by weather fronts of Mediterranean origin, which cause rainfall in the lowlands and snowfall in the mountains. In spring (ie March and April), the clash between air masses can cause thunderstorms and strong winds. In summer, from July to mid September, the country is reached by an offshoot of the Indian monsoon, but in most of the country it is not able to bring heavy rains, while it doesn't arrive at all in the western part. However, the hottest months are those that precede the monsoon, especially June, which is very hot in plains and hills, and up to quite high altitudes.
The monsoon affects Pakistan only marginally, and has an irregular pattern: during some years, it may have an unusual force, generating floods, while in other years, it doesn't even arrive. Rivers may overflow even at a great distance from the area where the heaviest rainfall occurred, which typically happen in the north. So, the great valley of the Indus and its tributaries may also be affected by widespread flooding in the southern area, where normally it doesn't rain much.
The cycle called ENSO can affect the monsoon's performance: in La Niña years, rainfall is heavier than normal, while El Niño brings drought.
In the lowlands of Pakistan, pollution is high, especially from October to February, and in large cities. In particular, in the north, Lahore is one of the most polluted cities in the world. In the south, Karachi is polluted even though it is on the coast, at least in winter, while from June to September, the pollution is lower because the wind comes from the sea.

Mountains

Northern mountains

In the mountainous areas of the north, the climate is continental up to high altitudes, with a wide temperature range between winter and summer, and often also between night and day. The temperature naturally decreases with altitude. The northern area, as well as being the coldest at equal altitude, is more prone to cold fronts brought by the westerly winds of the middle latitudes from December to May. But not all areas receive a lot of precipitation: it depends on slope exposure. The southern side (the mountains north of Peshawar and Islamabad) is much more rainy than the northern one.
In Kashmir, in the northernmost valleys of Khyber-Pakhtunkhwa and in the disputed region of Gilgit-Baltistan, yearly rainfall is at desert levels, below 250 millimeters (10 inches). Anyway, at higher altitudes, snowfalls quite frequently occur in winter, and above 4,500 meters (14,800 ft), vast glaciers are found, but the fact that the trekking season runs from April to October shows how this area is sheltered from the monsoon rains, although we cannot exclude some showers or thunderstorms, and maybe snowfalls on the highest peaks.
In Pakistan, there are two mountain ranges, the Karakoram and the Hindu Kush, that host some of the highest peaks on the planet, starting with K2, the second highest mountain in the world with its 8,611 meters (28,251 ft). The highest peak of the Hindu Kush is Tirich Mir, 7,708 meters (25,289 ft) high.
Skardu, located at 2,200 meters (7,200 ft) above sea level, is the starting point for climbing K2 and other peaks above 8,000 meters (26,200 ft); the climate here is arid continental, with an average ranging from -2.5 °C (27.5 °F) in January to 24 °C (75 °F) in July, when the average maximum reaches 32 °C (90 °F).
Here are the average temperatures of Skardu.

Precipitation in Skardu amounts to 250 mm (10 in) per year, with a relative maximum between winter and spring. Here is the average precipitation.

Expeditions to K2 are typically organized between the second half of July and early August. K2 and other peaks over 8,000 meters (26,200 ft) have a polar climate throughout the year, with strong winds that increase the sensation of cold.



On the southern side of the mountains, in the province of Khyber-Pakhtunkhwa (formerly North-West Frontier Province), the rains are plentiful, both those of winter and spring, which are caused by western disturbances, and those of the monsoon period, which are even heavier. Therefore, annual rainfall can exceed 1,500 mm (60 in) in the district of Abbottabad. The Ayubia National Park is definitely green and rainy.

Southwestern mountains

In the south-western part of Pakistan, there are other mountain ranges, such as the Chagai Hills and the Sulaiman Mountains; weather fronts in winter pass less frequently over this area, and the summer monsoon barely affects them as well. The result is a semi-desert climate, cold in winter, at least at night and above a certain altitude, while summer is hot even at relatively high altitudes.
The plateau of Baluchistan (or Balochistan) has an arid continental climate as well, cold in winter and hot in summer.
In Quetta, 1,600 meters (5,250 feet) above sea level, the monthly average temperature ranges from 4.7 °C (40.5 °F) in January to 29.5 °C (85 °F) in July. From December to March, the temperature at night usually drops below freezing (0 °C or 32 °F), but during the day it normally exceeds 10 °C (50 °F). Sometimes it can snow in winter, and intense frosts may occur at night, even as low as -15 °C (5 °F). On the other hand, in the summer months, the temperature can reach 40 °C (104 °F) despite the altitude. Here are the average temperatures.

In Quetta, 260 mm (10.2 in) of rain or snow fall in a year, the large part of which occurring from December to March. Here, the summer monsoon produces little effects, with only sporadic rains (although it depends on the years). Here is the average precipitation.

North

In the northern part of the Indo-Gangetic plain, corresponding to the region of Punjab (or Panjab), the "five rivers land", there is a sub-tropical climate, with a mild, relatively rainy winter (when, however, nights are cold), followed by a spring that becomes progressively warmer, and a very hot period from mid-April through June, when the temperature can reach 46/47 °C (115/117 °F). In spring, especially in March, tornadoes may occasionally occur because of the clash between different air masses. Before the monsoon, in May and June, a very hot wind blows, the Loo, which can bring dust storms as well as the rapid dehydration in animals and humans, and the desiccation of vegetation. Scattered thunderstorms may occur, causing ephemeral decreases in temperature.
The summer is sweltering, with some rain brought by the monsoon from July to September. The monsoon arrives between late June and early July, but it's not as intense as in other regions of India, and it's characterized by periods of bad weather alternating with long weeks with intense heat and drought. However, the rains, though rare, can be violent and concentrated in few hours or even in few minutes, and when they last a few days, rivers may overflow.
In winter, in Punjab (but also in northern Sindh), mists and fogs often form.
In Peshawar, in the northwestern region of Khyber Pakhtunkhwa, the monthly average temperature ranges from 11 °C (52 °F) in January to 32.5 °C (90.5 °F) in June, with highs around 39 °C (102 °F). In July and August, the daytime temperature drops a bit, but at the cost of an increase in humidity. In winter, between December and February, the temperature is mild during the day, with highs around 18/20 °C (64/68 °F), but it often gets cold at night, when the temperature can drop to around freezing. Here are the average temperatures.

In an average year, 410 mm (16 in) of rain fall. In winter and spring, some rains may occur, with a maximum in March of 75 mm (3 in), while the summer monsoon brings a maximum of only 70 mm (2.8 in) per month in August, although the rains may be heavier during some years: in the rainiest August ever, rainfall amounted to 450 mm (17.7 in). Here is the average precipitation.

The sun in Peshawar shines quite often even in winter, it reaches a maximum in May and June, and then the sunshine hours decrease a little because of the monsoon.

In Lahore, a large metropolis in Punjab, the climate is similar to that of Peshawar, but owing to the more southern position, the winter is a bit milder: the average ranges from 12 °C (53.5 °F) in January to 32.5 °C (90.5 °F) in June. Lying more to the east, the city is more exposed to the monsoon, in fact, it receives 625 mm (24.5 in) of rain per year, including 205 mm (8 in) in July and 170 mm (6.7 in) in August.
The capital of Pakistan, Islamabad, and the neighbouring city of Rawalpindi, are located at 500 meters (1,600 feet) above sea level, and are a bit cooler, and also much more rainy, since they are located at the foot of the mountains; in fact, they receive 1,250 mm (49 in) of rain per year, including more than 250 mm (10 in) per month in July and August. The average temperature in January is 10.5 °C (51 °F), and light frosts may sometimes occur at night. In summer, the rains lower the daytime temperatures more than in other cities, to 34/35 °C (93/95 °F) in July and August, but moisture becomes high.

Center and south

The driest part of the Indus plain is the central one, where disturbances in winter and spring are rarer, as well as the rains brought by the summer monsoon. In the eastern part of this area, we find the Cholistan Desert. Here, precipitation drops even below 100 mm (4 in) per year.
In south-central Pakistan, not too close to the sea, there is a particularly hot area, one of the hottest in the world, which includes the north of the Sindh province (see Jacobabad, Sukkur, Larkana , Mohenjo-daro) and the lowland areas of Balochistan (see Sibi, and Turbat in the southwest). In this area, during some years, in late May and early June, temperatures of 52/53 °C (125/127 °F) were reached.
For example, in Jacobabad, the average maximum temperature in May and June is 44 °C (111 °F). The effects of the monsoon are not evident, and in fact the rains are rare even in July and August, however, in this period the temperatures drop by a few degrees. Here are the average temperatures.


More to the south, in Hyderabad, in the Sindh province, the winter temperatures are even milder, while in summer, they are a little lower because of the proximity to the sea. Precipitation is still low, and amounts to 180 mm (7 in) per year, with a maximum of 60 mm (2.4 in) per month in July and August. Here are the average temperatures.

South-west

In the south-west, at the lowest altitudes of the plateau of Baluchistan, the climate is subtropical desert. Winter is mild, although sometimes at night it get cold, while summer is definitely hot. At around 800/1,000 meters (2,600/3,300 feet) above sea level (see Panjgur), the average maximum temperatures in summer are around 40 °C (104 °F).
Only in the south, there are some inland valleys around sea level: in the aforementioned city of Turbat, located in the Kech River Valley, the average maximum in June is 44 °C (111 °F), which drops to 40 °C (104 °F) in July. This is a slight effect of the monsoon, which, however, brings very few rains: only 110 mm (4.3 in) per year, of which 25 mm (1 in) in July. Here the temperature reached 53.5 °C (128.3 °F) in late May 2010, one of the highest values in the world, surpassed only by Death Valley, California.

Coast

In the far south, along the coast of the Arabian Sea, the climate is tropical, since winter becomes milder, there is also one a reduced temperature range between winter and summer. Rainfall is at desert or semi-desert levels; it is lower, about 100 mm (4 in) per year in the western sector (ie the coastal region of Balochistan called Makran, see Jiwani), which receives little rainfall from the summer monsoon (but in return it receives some rare rains in winter), while it is slightly more abundant, about 200 mm (8 in) per year, at the mouth of the Indus River, where the rains basically occur only from June to September.
In Karachi, the megalopolis located on the edge of the Indus delta, the average temperature ranges from 19 °C (66 °F) in January to 32 °C (89.5 °F) in June. Here, winter is pleasant and sunny (although it can sometimes be cold during the night). In the months preceding the monsoon, there can be scorchingly hot days, with peaks of 42/44 °C (108/111 °F), but it's more common for the temperature to remain about 35 °C (95 °F), though with a high humidity. Here are the average temperatures.

From June to September, the monsoon season, it doesn't rain a lot: about 200 mm (8 in), including 80 mm (3.2 in) in July, but here too, this season can be very rainy during certain years. In July and August, the weather is often cloudy and the heat is sweltering, especially in the interior of the city, while coastal districts receive a fairly steady breeze from the sea. Here is the average precipitation.

The temperature of the Arabian Sea is warm enough for swimming all year round, while it becomes very warm in summer. Here are the average sea temperatures near Karachi.

Tropical cyclones

---

The southern part of Pakistan can be affected by tropical cyclones, especially the south-east (coast of Sindh): Karachi, the large city located right on the coast, is the most at risk; sometimes the coast of Makran can be interested as well, though more rarely. Cyclones form from May to November, and are more frequent and intense at the beginning of the period mid-May-early June) and less at the end (October), while from July to September, when the monsoon is at the height of activity in India, they generally do not occur. In November, they typically affect the southern part of India and the Arabian Peninsula, but do not reach Pakistan.
Particularly intense cyclones hit Pakistan in May 1999 and in June 2010 (the latter was called cyclone Phet).
