Climate - El Salvador

El Salvador, a small country of Central America located at 13-14 degrees north latitude and overlooking the Pacific Ocean, has a tropical climate, hot all year round along the coast and below 1,000 meters (3,300 feet), which are called tierras calientes, with little difference in the temperature (only a few degrees) over the seasons. The real difference is found in rainfall and humidity: there is a rainy season from late April to October which is also definitely muggy.
In inland areas, there are volcanoes, plateaus and mountains, where the weather gets cooler with altitude. At intermediate altitudes, cloud forests are found; at high altitudes, above 2,000 meters (6,500 feet), it can get cold on winter nights. The highest point is Cerro El Pital, although the summit, 2,730 meters (8,957 feet) high, is located in Honduras; from November to March, you can see the snow on the top.

From December to March, El Salvador is sometimes affected by the Norte, a cool wind from the United States, which can bring a bit of cool weather in the evening and at night at sea level, with lows around 20 °C (68 °F) on the coast and 16/17 °C (61/63 °F) in inland plains, and even more so in San Salvador, with lows around 13 °C (55 °F).

San Salvador

The capital, San Salvador, is located at 700 meters (2,300 feet) above sea level, so it's still in the tierras calientes, but the altitude makes the heat more bearable, in fact, the maximum temperature ranges from 30 degrees Celsius (86 °F) between September and November to 32.5 °C (90.5 °F) in March and April, which are, although slightly, the hottest months, before the rainy season. The hottest days of the year occur from March to May, when the temperature can reach 35/36 °C (95/99 °F).
The night minimum drops a few degrees below 20 °C (68 °F) from November to April. Anyway, even here, the rainy season, from May to October, is sultry. Here are the average temperatures.

In San Salvador, 1,750 millimeters (68 inches) of rain fall per year. From June to September, it rains a lot, about 300 mm (12 in) per month, distributed in 20 days; on the other hand, it almost never rains from December to March. Here is the average precipitation.

Rainfall occurs mainly as downpour or thunderstorm in the afternoon, so the amount of sunshine, which is great in the dry months, remains acceptable even during the rainy season. Here are the average daily sunshine hours.

Acajutla

Along the coast of the Pacific Ocean, the heat is more intense, so much so that lows range from 23 °C to 25 °C (73 °F to 77 °F) and highs from 32 °C to 33 °C (89.5 °F to 91 °F). There can be very hot days, especially in March and April, before the rains, when the temperature can sometimes reach 37/38 °C (99/100 °F).
During the rainy season (which occurs in the same period as in San Salvador), the weather is hot and muggy. In the inland valleys located at low altitude, the distance from the sea makes the heat even more uncomfortable because they are not reached by the sea breeze.
Here are the average temperatures of Acajutla, located in the western part of the coast.

The rains on the coast follow a similar pattern to that of the interior. Here is the average rainfall in Acajutla.

In Acajutla, the sun often shines, more than 3,000 hours a year. The sunniest period is the driest, from December to March.

For a beach holiday, the sea in El Salvador is warm throughout the year, in fact, the water temperature ranges from 28 °C (82 °F) to 30 °C (86 °F), as we can see in the following table.

Hurricanes

---

In the period from June to November, but especially between August and October, El Salvador can be affected by hurricanes. The hurricanes coming from the east, ie from the Caribbean Sea, release most of their energy over Honduras, but they can still bring heavy rains in Salvador, especially in inland and mountainous areas. Then, there are depressions and tropical storms that can be formed on the Pacific, as early as in mid-May; they are usually not intense because they affect the country in the early stages of their formation, but they can still bring heavy rains, which can in turn cause landslides and floods.
