The Southern Zone of Costa Rica—home to stunning towns like Uvita, Ojochal, and Chontales—is a year-round tropical paradise. But depending on your travel style, tolerance for rain, and interest in wildlife sightings or local festivals, some months may suit you better than others.
Let’s walk through the year, month by month, so you can plan your visit with confidence and maybe even a little local flair.
January
January kicks off the year with beautiful blue skies and sunny days. It’s peak dry season, making it ideal for beach outings, hiking, and waterfall swims. Whale watching is in full swing, and the scenery is vibrant from recent rains. But with all that beauty comes popularity—expect more tourists and higher prices. New Year’s Day (Jan 1) is celebrated with fireworks and beach gatherings across the country. Average temperatures: 27°C (81°F) daytime / 21°C (70°F) nighttime.
February
If you love consistent sunshine and low humidity, February might be your month. It’s perfect for exploring the jungle, taking long walks on the beach, or heading out on a wildlife tour. Just remember, this is still high season, so book ahead. While there are no major holidays, Valentine’s Day (Feb 14) is often celebrated with romantic dinners at local resorts. Average temperatures: 29°C (84°F) daytime / 22°C (72°F) nighttime.
March
March offers continued dry weather with slightly thinner crowds than February. It’s a great time for peace and relaxation. Waterfalls may begin to run a bit lower, but the ocean is warm and inviting. Día de San José (Mar 19) is more of a capital-city celebration, so the Southern Zone stays relatively calm. Average temperatures: 30°C (86°F) daytime / 22°C (72°F) nighttime.
April
This month straddles the end of the dry season. The days get hotter, but the landscapes remain lush. April also brings Semana Santa (Holy Week), one of Costa Rica’s most important holidays. Expect busy beaches and closed shops from Thursday to Sunday, especially if your visit overlaps with Easter. Average temperatures: 31°C (88°F) daytime / 23°C (73°F) nighttime.
May
Welcome to the green season! May brings refreshing afternoon rains that breathe life back into the forest. Mornings are generally sunny, making it a great time for early hikes or coffee on the balcony. With fewer crowds and lower prices, it’s a peaceful time to visit. Just be prepared for occasional mud and Labor Day (May 1), when banks and government offices are closed. Average temperatures: 30°C (86°F) daytime / 23°C (73°F) nighttime.
June
Rain showers become more regular, typically in the afternoons or evenings. Mornings are usually clear, perfect for birdwatching and nature tours. June is a quiet month, offering solitude and savings. Father’s Day (third Sunday in June) is widely celebrated with family barbecues, though it won’t affect your travel plans much. Average temperatures: 29°C (85°F) daytime / 22°C (72°F) nighttime.
July
Here’s a surprise: July often experiences a short dry spell known as the “Veranillo de San Juan.” Mid-month can feel like a mini summer, with plenty of sun between the rains. Whale season begins, and the jungle stays green and alive. Costa Rica also celebrates Annexation of Guanacaste Day (July 25) with parades and festivities, even in smaller towns. Average temperatures: 29°C (84°F) daytime / 22°C (72°F) nighttime.
August
August is lush, quiet, and deeply peaceful. It’s the beginning of humpback whale season and a great month for nature lovers who don’t mind a little rain. Afternoon showers are common, so plan your outdoor time in the mornings. Mother’s Day (Aug 15) is a big holiday here—expect locals traveling and restaurants to be busy. Average temperatures: 28°C (82°F) daytime / 22°C (72°F) nighttime.
September
This is the wettest month of the year, but also one of the most beautiful. The landscape is at its greenest, and whale watching is at its peak. If you don’t mind working around the rain, you’ll enjoy a very authentic and tranquil experience. Independence Day (Sept 15) is widely celebrated with parades, music, and dancing—even the smallest villages join in. Average temperatures: 27°C (81°F) daytime / 22°C (71°F) nighttime.
October
October continues the rainy trend, but for those who enjoy quiet retreats, it’s a hidden gem. Waterfalls are roaring, the forest is buzzing with life, and the tourist crowds are gone. Some restaurants and tours may pause for a break, so check ahead. No major national holidays this month, but you may find local celebrations and cultural festivals. Average temperatures: 27°C (81°F) daytime / 21°C (70°F) nighttime.
November
By November, the rain starts to ease up, and the Southern Zone prepares for the return of the dry season. It’s a sweet spot for travel—green scenery, better roads, and excellent prices. Holidays like All Souls Day (Nov 2) and Teacher’s Day (Nov 22) are observed, but you likely won’t notice any disruptions. Average temperatures: 27°C (81°F) daytime / 21°C (70°F) nighttime.
December
December ushers in the dry season with clear skies and festive energy. The first half of the month is quieter, with better deals, but after mid-December, the holiday rush begins. The beaches buzz with activity, and towns glow with lights and celebrations. Christmas (Dec 25) and New Year’s Eve (Dec 31) bring fireworks, music, and family feasts—Costa Rica knows how to throw a party. Average temperatures: 27°C (81°F) daytime / 21°C (70°F) nighttime.
