Weather details in september

Climate conditions throughout the Costa Rican territory are characterized by the abundance of rain and the permanent presence of heat. Prepare to have rainy days because the climate in Costa Rica throughout September is far from pleasant, despite the slight decrease in precipitation.

Costa Rican East Coast in September

Compared to the abundance of rain in other parts of the country, the rainfall on the Caribbean coast is acceptable. Only due to the rise of heat, scorching middays succeed the comfortable mornings. It will then be necessary to arrange to stay away from the sun, at the most uncomfortable hours of the day.

The Center of Costa Rica in September

The central plateau is the most wet in Costa Rica. Beginning at daybreak, expect rainfall events that can range from moderately intense to very intense. Even if the temperatures are lower compared to those on the coasts, the weather in Costa Rica throughout September is far from pleasant.

The West Coast of Costa Rica in September

Depending on the geographical location of the cities, the heat can be pleasant or unbearable. Maximum temperatures range from 24° C to 32° C. Either way, the heavy rains rarely provide the opportunity to enjoy sunny days.
