What would be the best month to go to Costa Rica in the second half of the year?
July, November, December. July is the second little summer in guanacaste usually and November, December is start of the high season.
If you dont mind the rainy season (some people love it, since its all green, less crowded and doesnt mean its raining all day everday) good months are august, september.
I’d just avoid october since its usually the month with the most rain..
