Introduction

---

In the Philippines, an archipelago of Southeast Asia, consisting of thousands of islands and extending from 5 to 20 degrees north latitude, the climate is generally tropical maritime, with a relatively cool season from December to February, when the north-east trade winds prevail, and a hot, humid and rainy season from May to November, when the south-west monsoon prevails.
Between March and May, before the arrival of the summer monsoon, the temperature increases and reaches the highest levels of the year, especially in the center-north and in the interior of the larger islands: hence, in general the coolest month (or the least hot) is January, while the warmest is May.
In the north of Luzon, cool air masses can sometimes arrive from December to March, so much so that at night the temperature can drop to around 12/15 °C (54/59 °F). On the southernmost islands, close to the Equator, temperatures are more stable, and remain high all year round.
Relative humidity in the Philippines is almost always high as well, and makes the heat muggy, at least in the lowlands.
Some areas (usually the eastern coast, facing the Philippine Sea), have an equatorial climate, ie rainy throughout the year. In fact, during winter, the northeast trade winds release large amounts of moisture as rain on the exposed coasts and slopes. This, in general, rarely happens on the inner islands, which are more sheltered, and even less along the western slopes, where winter is a dry season.
The tropical rains typically occur in the form of downpours or thunderstorms, except during tropical storms and typhoons, which can last for a few days and are accompanied by strong winds.

Equatorial climate

---

In summer, it rains all over the Philippines; the equatorial climate zones are those in which it rains even in winter, that is, those exposed to the northeast winds. They are the eastern part of the island of Luzon, some of the Eastern Visayas, such as the island of Samar and the eastern part of Leyte, the north-east of Mindanao and the smaller southern islands. In these areas, more than 100 millimeters (4 inches) of rain fall per month even in winter, which is often the rainiest season. In fact, these areas, just because they are exposed to the north-easterly winds, are generally at least partially sheltered from the summer monsoon, which as mentioned blows from the south-west. In these areas, the annual precipitation exceeds 2,500 mm (98 in), but in most of the eastern coast it exceeds 3,000 mm (118 in), and in some cases it can even exceed 4.000 mm (157 in).
Being rainy throughout the year, these areas of the Philippines honestly do not have a beautiful climate, and not surprisingly here you won't find large cities.
The least rainy period varies depending on area, and as weeks pass it advances proceeding from north to south: in Legazpi (Luzon Island), rainfall drops below 200 mm (8 in) per month from March to May, while in Borongan (Samar Island), this happens from July to September.

Legazpi

Here is the average precipitation in Legazpi, located in the south-east of the island of Luzon.

In Legazpi, temperatures are high all year round, however, they decrease a bit from December to February. Here are the average temperatures.

Despite the frequent rains, the sun in Legazpi shines for an acceptable number of hours, especially in the least rainy period, as we can see in the following table.

The sea in Legazpi is warm all year round, as can be seen in the following table.

The southernmost islands (Basilan, Sulu, Tawi-Tawi), which lie north of Borneo, must be put into the equatorial climate zone, ie where it rains even in winter, but since it doesn't rain too much in this season, you can visit them from February to April, and after all even from June to September, when, however, it rains on average every other day.

Tropical climate

---

In the rest of the Philippines, the climate can be defined as tropical, since it is possible to identify a dry season, which usually runs from February to April, but in the most sheltered areas the rains are rare even in December and January. The dry season is more evident in the western part (blue area), while it's less evident, but still present, in the central part (green area); in contrast, the summer monsoon is generally more intense in the western part.
In this area, the biggest cities of the Philippines are found, starting from the capital, Manila.

Batanes and Babuyan

The northernmost islands (Batanes and Babuyan) are located far to the north, almost at the Tropic; in winter, they are affected by cool air masses from the Asian continent, so the weather is pretty cool from December to February, with average highs around 24/25 °C (75/77 °F).
Sometimes, from December to February, there can be days a bit cool, with lows around 15 °C (59 °F) and highs around 20 °C (68 °F) or even slightly below.
Here are the average temperatures of Santo Domingo de Basco, located in the far north of the Philippines, in the Batanes Province.

From the point of view of the rains, these islands are in the intermediate area, the one circled in green. The wettest period is from July to December, but even January is often very rainy, in fact, in this month the rains still amount to 145 mm (5.7 in). It goes a bit better in February, but the driest months here are March and April, so they will be the ones to be preferred for a visit.
Here is the average precipitation in Basco.

In winter, the sea is warm enough for swimming even in this northernmost part of the Philippines, although as we mentioned the air can be a bit cool.

In the interior of the norther island of Luzon, the increase in temperature before the monsoon, i.e. from March to May, is fairly noticeable: there are hot cities like Angeles, San Fernando, Tarlac, Cabanatuan and Tuguegarao, which in this period easily reach 35/37 °C (95/99 °F), but with peaks of 40 °C (104 °F).

Manila

The metropolitan area of Manila and Quezon City is located in a better position because it is situated on the coast, and therefore it gets some breezes, however, being a big city, the so-called urban heat island effect is evident. In addition, Manila is located on a bay, while to the southeast is the Laguna de Bay, which provides additional humidity.
In Manila and Quezon City, it's hot all year round, since the maximum temperature is around 30 °C (86 °F) even in winter.
The hottest months are April and May, when the average maximum temperature is around 34 °C (93 °F) during the day.
During the rainy season, from June to October, the average highs drop to around 31/32 °C (88/90 °F), although night temperatures remain high, around 25/26 °C (77/79 °F), and the higher humidity makes the heat muggy.
Here are the average temperatures at the airport.

The dry season, from January to April, is very pronounced, in fact, it rains very rarely. The rainiest months is August, with about 475 mm (18.5 in) on average. Here is the average precipitation.

The amount of sunshine in Manila is better in the dry period, while during the rainy season, the sun shines on average for a few hours a day.
Near Manila too, the sea is warm all year round, with less variation from month to month than in the north.
The best months to visit Manila are January and February, since they are the least hot within the dry period.



On the island of Boracay, located at 300 km (190 miles) south of Manila, approximately 2,500 mm (98 in) or rain fall per year; the rains are abundant from May to October, while from January to April it rarely rains. Already in December, however, showers and thunderstorms become quite rare (on average, 6 per month).

Cebu City

In Cebu City, the temperatures are high throughout the year, although they are slightly lower from December to February. Compared to Manila, the heat is less intense in the period before the monsoon, and on the hottest days, the temperature generally reaches 35 °C (95 °F) from April to June. Here are the average temperatures.

Cebu City is located in the group of the central islands (Visayas), which are more sheltered, so they are moderately rainy but without excesses. Here, about 1,550 mm (61 in) of rain fall per year, of which less than 100 mm (4 in) fall from February to May. For many months of the year, it rains on average every second day, except during the period from January to May. We are in the intermediate zone (the one circled in green), where the dry period is present but less pronounced, January is still a pretty rainy month, and therefore the best period is from February to April. Here is the average precipitation.

The sun in Cebu frequently shines in the dry season, while in the rest of the year it does not shine too often.

Davao City is located in the south of Mindanao, overlooking the gulf of the same name, and a short distance from mountains such as Apo and Leonard Kniaseff. Here we are at the boundary between the tropical and the equatorial climate zones; annual rainfall amounts to 1,835 mm (80 in), without there being a well-defined dry season, although between February and April, precipitation drops to around 105/115 mm (4.1/4.5 in) per month.
The least rainy area of the Philippines is the protected Sarangani Bay, in the far south of Mindanao. In General Santos, 960 mm (37.7 in) of rain fall per year, with a maximum of about 100 mm (4 in) per month, and therefore not a large amount, in the summer months.

Mountains

---

In the Philippines, there are many mountains and volcanoes, the highest of which is the aforementioned Mount Apo, in Mindanao, 2,954 meters (9,691 ft) high. Along the mountain slopes, usually the rains are more abundant than in the plains, and as mentioned, on the slopes exposed to the wind, showers and thunderstorms are possible throughout the year.

Baguio

In Baguio, at 1,500 meters (5,000 feet) above sea level, on the island of Luzon, 3,800 mm (152 in) of rain fall per year; the rains are plentiful especially in July and August, with almost one meter (3.3 feet) of rain per month! Here is the average precipitation.

However, there is little rain from December to March, in addition, the temperature is mild because of the altitude, so Baguio is a haven to escape from the heat of the cities of the plains, especially in the hottest period of the year, ie in March and April, before the rainy season.
From December to February, on colder nights, the temperature typically drops to around 10 °C (50 °F), but it can sometimes drop as low as 7.5 °C (45.5 °F), as happened in January 2009 and February 2017.
During the day, sometimes the maximum can remain around 18/19 °C (64.5/66 °F), both in winter, during the cooler periods, and in summer, due to rain and cloudy skies.
On the hottest days of the year, the temperature typically reaches 30 °C (86 °F) from April to June.
Here are the average temperatures.

The sun in Baguio shines often in the dry season, although fog can form at night and in the early morning, while in the rainy season it can be seen for a few hours a day.

Typhoons

---

The Philippines are struck in full force by tropical cyclones, which in south-east Asia are called typhoons. The only area that generally remains outside of their trajectory is the southernmost one, ie the island of Mindanao, especially in the central and southern part, the south of Palawan and the small southernmost islands.
Typically, typhoons occur from May to December, although they are more frequent between August and November.
Sometimes, destructive typhoons occurred even in December, for example, Typhoon Bopha, which affected the Philippines in early December 2012, Typhoon Hagupit, which struck the islands around December 10, 2014, Typhoon Tembin, which hit Mindanao from 20 to 25 December 2017, and Typhoon Rai (also called super typhoon Odette), which hit the north of Mindanao and the central islands from 16 to 19 December 2021.
Since the sea is always warm, typhoons can in theory occur even from January to April, although in general, during this period, only tropical depressions not intense are formed, which can sometimes release considerable amounts of rain anyway, especially on the eastern slopes.

El Niño

---

The Philippines are also affected by the phenomenon known as El Niño, which during some years alters the climate of large areas of the world, and in the Philippines brings heat, drought and fewer typhoons than usual, while the opposite phenomenon, La Niña, brings heavier rainfall than normal and slightly lower temperatures.
