What’s the Weather in Costa Rica in August Like?
Even though in general Costa Rica is in the rain or green season, the start of the month usually has a drier start because of the mini dry seas. This is the period where the rainfall is decreased significantly from July through mid-August. Gradually, the rains start to pick back up towards the later part of the month. Generally it is a good idea to have light rain gear wherever you go, especially on the Caribbean side.
Through August, the Norwest Pacific is mostly still dry. Daytime temps are generally in the upper 80s to the low 90s. The rains are beginning to become more frequent, however they usually occur in the late afternoon and early evening.
As the month goes on, the Central Pacific will begin to be more impacted by the rains. At the start of the month, the rain will be almost daily in the later afternoon. Going towards the end of the month, rain will start to be more prevalent in the early afternoon. The temperatures will begin to drop a bit with day time highs in the mid-80s.
As the green season continues, the South Pacific is getting more wet. The rains each day start to happen earlier in the afternoon, become heavier and last longer. Temps will remain in the upper 80s and lower 90s.
The Caribbean starts to dry out while this is happening to the Pacific. As August goes on, it becomes drier and drier. Temps will still be high with highs during the day around the low 90s.
Arenal and the Central Valley will still be comfortable in August, around the upper 70s. Much like the Pacific coastal areas, the start of the month generally is nice with daily showers in the afternoon. As the month goes on, rains are more frequent, with harder rains in September.
