Nosara's Two Seasons: What the Weather Is Like Year-Round

Nosara has two seasons, not four: a dry season that runs mid-December to mid-May, and a rainy season from mid-May to mid-December. Both are warm. What changes is the light, the color of the land, and how much water moves through it. The Sanctuary Estate sits on 16.3 acres in Guanacaste, on the Pacific side of the Nicoya Peninsula, so it sees both seasons up close.

What is the dry season like in Nosara?

From mid-December through mid-May, the skies stay clear and the rain mostly stops. As the trees drop their leaves, they flower instead. You’ll see whites, oranges, purples, and pinks come out across the hillsides, set against the mountains that ring the property.

Nights are the other reason people like this stretch. There’s little light pollution here, so the stars are easy to read from the veranda or the pool. If you want long, dry, bright days, this is the window.

What is the rainy season like in Nosara?

From mid-May to mid-December, the rain returns and the whole landscape turns green. The trees fill back in, the air smells of wet earth, and wildlife is more active. Rain here often comes in the afternoon and clears, rather than lasting all day.

Two things stand out in these months. Rainbows are common after a shower, sometimes doubled across the valley. And seasonal waterfalls open up on the mountains to the north after heavy rain. You can hear and see them from the pool area, the parking area, and even the upstairs bathroom.

The dry season is for clear skies and stars. The rainy season is for green hills and waterfalls.

When is the best time to visit Nosara?

It depends on what you’re after. Come in the dry season (roughly December through April) for reliable sun, flowering trees, and the best stargazing. Come in the green season (May through November) for lower crowds, a greener landscape, and the seasonal waterfalls. Neither season gets cold.

What is the estate like across the seasons?

The property sits high enough to keep the views open year-round, whether you’re eating outside, in the pool, or looking out over the gardens. It was built with sustainable materials and practices, in step with how Nosara tends to build.

For families, two well-regarded bilingual schools are nearby: Del Mar Academy and Casa de las Estrellas. Both lean into creativity, environmental learning, and hands-on education.

The short version: Nosara has a dry season (mid-December to mid-May) with clear skies, blooming trees, and strong stargazing, and a rainy season (mid-May to mid-December) with green hills, frequent rainbows, and seasonal waterfalls. The estate’s 16.3 acres put you in front of both.
