The best time to visit Costa Rica is during the dry season, which runs from mid-December to April. This "summer" period offers nearly guaranteed sunshine and dry trails, making it ideal for hiking through the rainforests or relaxing on the Pacific beaches. However, this is also the "high season," meaning hotel prices are at their peak and popular spots like Manuel Antonio can be crowded. For those looking for a balance of lower costs and lush scenery, the "Green Season" (May to June or November) is highly recommended. During these transitional months, you can expect sunny mornings followed by brief afternoon rain showers that keep the landscape vibrant and green. In 2026, savvy travelers often target July and August for a "mini-dry season" (veranillo) on the Pacific coast, though they generally avoid September and October, which are the wettest months with a high risk of tropical depressions on the Caribbean side.
