In Guatemala,
the climate is tropical, hot all year round in the lowlands, while in mountainous areas, it becomes cooler with increasing altitude.
Geographically, the country is divided into three zones: in the north, there's an area almost entirely occupied by plains (departments of Petén, north of Alta Verapaz, and Izabal), with a short stretch of coastline on the Gulf of Honduras (Caribbean Sea); in the center, there's a large mountainous area, where the capital is also located; and finally, in the south, we find a thin flat strip south of the mountains, overlooking the Pacific Ocean.
From December to March, Guatemala can be reached by
cool air masses from the United States, and in these cases, the temperature at night can drop below 10 °C (50 °F) in Guatemala City, and around 13/15 °C (55/59 °F) in the plains.

Equatorial climate
In almost all of Guatemala, there is a
dry season from late November to mid-April, when the northeast trade winds blow, and a rainy season, from May to October, when the predominant currents come from the south-west.
However, north of the mountains and near the Gulf of Honduras, there is also an area where it rains all year round; in fact, in winter the trade winds reach the coast after picking up moisture from the sea, or they are forced to rise when they encounter the first mountain slopes. Although the rainfall still amounts to about 100 millimeters (4 inches) per month, the best period here is from February to April, since it goes better than in the rest of the year. Owing to the abundance of rainfall, the climate here can be defined as
equatorial, and in fact, the area is occupied by a rainforest.
The area we are dealing with, which does not have a dry season, is shown in the following map.

Pacific coast
Let us now look at the areas having a dry and a rainy season.
To get an idea of the rainfall pattern on the south side, we can have a look at the precipitation data of
Mazatenango, located at 370 meters (1,200 feet) above sea level, about 50 kilometers (30 miles) away from the southern coast. As we mentioned, there is a rainy season from May to October.

Along the
south coast, the heat is intense throughout the year; in winter, the trade winds warm up as they descend on the leeward side of the mountains. So, the winter here is hot, with highs around 30/32 degrees Celsius (86/90 °F), but sometimes even above; on the positive side, it's sunny and not too humid. In March and April, before the rains, the hottest days occur, with peaks above 35 °C (95 °F).
Here are the average temperatures of
Puerto San José, on the south coast.

The north
In the
north, the Department of Petén is a bit cooler in the winter months, when high are around 26/28 °C (79/82 °F). Starting in March, the temperatures rise, reaching pretty high values. From May to October, the temperature drops a bit, but the heat becomes definitely sultry, as happens in all the lowland areas of Guatemala in the rainy period.
Flores

In this area, we find the Mayan site of Tikal, surrounded by the forest (the National Park of the same name is a UNESCO World Heritage Site). Here, the best period is from February to April; in December, and partly also in January, it still rains quite a lot. It is also true that December and January are not as hot as the period from March to May, when there can be uncomfortably hot days.

Hills and mountains
In the
central area of Guatemala, occupied by mountains and plateaus, rainfall is scarce from December to April, as happens in the south, while the temperatures vary with altitude. During the rainy season, the rains are usually plentiful, but there are also some sheltered slopes which experience only moderate rains.
Guatemala City
The capital,
Guatemala City, is located in the so-called
tierras templadas, 1,500 meters (5,000 feet) above sea level, and has a spring-like climate all year round: the average daytime temperatures range from 23 °C (73 °F) in November and December to 28 °C (82 °F) in April. Temperatures are rarely too hot, even though they may exceed 30 °C (86 °F) from February to May. At night, the temperature is cool, sometimes a bit cold, actually, it can drop below 10 °C (50 °F). The city is also quite windy. Here are the average temperatures.

Although the tropical rains occur mainly in the form of heavy showers and downpours, the amount of
sunshine in the rainy season is not good because cloudiness usually begins to develop in the warmest hours. Here are the sunshine hours per day in Guatemala City.

Quetzaltenango
In
Quetzaltenango, located at 2,300 meters (7,500 ft) above sea level, and therefore in the
tierras frìas, the climate is cooler: the average temperature in January is only 12 °C (54 °F), with a remarkable difference between night and day, so much so that at night it often drops to around freezing (0 °C or 32 °F). From April to August, the daily average is 15/16 °C (59/61 °F). Here are the average temperatures.

Here too, there is a pronounced rainy season, but the rainfall amounts to just 800 millimeters (31.5 inches) per year, compared with 2,000/3,000 mm (78/118 in) of the rest of the country. This happens because the chain of mountains and volcanoes to the southwest partly blocks the moist air masses coming from the sea. However, rainfall exceeds 100 mm (4 in) per month between May and October. Here is the average precipitation.

The relatively arid area, where Quetzaltenango is located, is shown in the following map.

In Guatemala, there are as many as 37
volcanoes, the highest of which is
Volcán Tajumulco, which stands out with its 4,220 meters (13,845 feet) and is also the highest peak in Central America. Above 3,500 meters (11,500 ft), at night, it can freeze throughout the year.
Hurricanes
Guatemala is located in the path of tropical storms and
hurricanes, which may affect the country in the period from June to November, however, they are most likely from August to October. Usually, they come from the east, from the Caribbean Sea, but sometimes, tropical depressions can also form on the Pacific Ocean, which can especially affect the western part of the country, as early as in mid-May.
Generally, the country is hit less intensively than Honduras; however, tropical storms and cyclones can cause heavy rains, which can trigger landslides and floods. Some hurricanes that hit the country in the past were Francelia in early September 1969, Fifi in mid-September 1974, Mitch in late October 1998, Keith in early October 2000, Iris in early October 2001, Felix in early September 2007, and Earl in early August 2016.
Best Time
The best time to visit Guatemala runs from
December to mid-April on the central plateau and on the southern side, and corresponds only to the period from February to April along the Caribbean coast and in the Petén Department.
What to pack
In Guatemala City and the tierras templadas: all year round, bring light clothing, a sweatshirt or sweater and a jacket for the evening; a raincoat or umbrella from May to October.
In plains and coasts: bring lightweight clothes throughout the year; in the rainy season, a light sweatshirt and a light raincoat for thunderstorms.
When going to the reef, you can bring snorkeling equipment, including water shoes or rubber-soled shoes.
On high mountains: warm clothes, a jacket, a hat, gloves, and hiking shoes.
Up
