La Fortuna, Costa Rica is near the equator, so air pressure is generally high. The town's location near Arenal Volcano and Lake Arenal creates a unique microclimate.
The mountain's slope and elevation create an orographic effect, where air rises, cools, and condenses, resulting in high air pressure. The lake's humidity also contributes to the pressure.
During the dry season (December to April), the air is drier and pressure is higher. The rainy season (May to November), the air is more humid and precipitation increases. La Fortuna's tropical savanna climate means high air pressure throughout the year, with slight changes between seasons.
