What's the weather like in Tamarindo by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Tamarindo during Jan–Apr, Dec?
Costa Rica's sunniest and driest period — virtually no rain, daily 32°C, brown landscape, and peak tourist density. Christmas/New Year and Easter Week are absolute peak with hotels at 200% normal rates.
Shoulder season (May, Nov) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jun–Oct) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
