The best months to travel to Costa Rica are typically during the dry season, which runs from December to April. During these months, you can expect less rainfall, sunnier days, and more favorable conditions for outdoor activities and exploring the country's natural attractions. The dry season is also considered the high season for tourism, so expect more crowds and higher prices for accommodations and activities. If you prefer to avoid crowds and don't mind occasional rainfall, you can consider traveling during the "green season" or the shoulder months of May, June, September, and October. During this time, the rains are generally manageable, with short afternoon or evening showers, and the lush landscapes are particularly vibrant. Prices for accommodations and activities are often lower during the green season, making it an attractive option for budget-conscious travelers. Keep in mind that Costa Rica's climate can vary depending on the region, so it's essential to research your specific destinations to determine the best time for your visit.
