What is the best time to visit Yasuní National Park?
The Yasuní National Park is defined by its vibrant equatorial climate, creating a warm and humid sanctuary for life year-round. With a consistent average temperature of approximately 25 °C (77 °F), the region remains lush and spectacular regardless of when you choose to visit.
Yasuní climate and rainfall by month
The heartbeat of the Amazon is its rain. While the park is evergreen, the precipitation follows a seasonal rhythm that affects river levels and wildlife spotting:
- The Wet Season (March – June): Rainfall peaks in April with an average of 315 mm (12.4 in), and May and June follow close behind at 307 mm (12.1 in). Rivers and lagoons are high, which makes these months ideal for exploring by canoe and the best time to spot anacondas and caimans. The trails stay open all year; they are just a little muddier.
- The Drier Season (July – February): The driest month is August, with approximately 192 mm (7.6 in) of rainfall. Trails are firmer in this period, which suits those who prefer exploring the jungle floor on foot.
There is a difference of roughly 123 mm (4.8 in) of precipitation between the driest and wettest months, with an annual temperature variation of only 1.8 °C (3.2 °F). Even the driest month brings close to 200 mm (8 in), so rain is part of every season, and every tour runs all year round.
Yasuní season by season
March – June: high water
The wettest months, with April peaking at 315 mm (12.4 in). Rivers and lagoons rise, so the canoe takes you further along creeks and into the lagoons: the best time for caimans, anacondas and river wildlife. Showers come almost daily, but mostly short, and the trails are simply a little muddier.
July – August: the driest weeks
August is the driest month at 192 mm (7.6 in), and July and August are also the coolest, around 23.7 °C (75 °F). Trails are firm, so long walks and the canopy tower are at their best. These are our busiest weeks: book early.
September – February: warm and drier
Around 200 to 230 mm (8 to 9 in) a month and the warmest days of the year, about 25.4 °C (78 °F). Rivers sit lower, trails stay walkable and showers come and go. December to February is holiday season at the lodge, so book early for those dates.
Which tour for which month
High water: March to June
The 4- and 5-day Wildlife & Kichwa tours spend most of their time on the water, so high water works in your favour: more canoe, more river wildlife.
4-day Wildlife & Kichwa tour →Drier trails: July to February
The 9-day Waorani expedition and the birding tours walk the most. Firmer trails and dawn starts make the drier months the natural choice for them.
9-day Waorani expedition →Any month: short on time
The 3-day express fits a long weekend and still gets you to the lodge, the forest and the river. Every tour runs all year, rain or shine.

To make the most of your adventure at Sinchi Wayra, keep these essentials in mind:
- Relax and Disconnect: You are in one of the most biodiverse places on Earth. Take a deep breath and let the sounds of the jungle replace the noise of the world.
- Stay Hydrated: The humidity is high (averaging 80%+). Keep water with you at all times.
- Cooler Nights: While days are warm, nights in the forest can feel surprisingly fresh. A light sweater or long-sleeved shirt is recommended for evening boat rides.
- Rain Protection: Sudden showers are part of the experience. We recommend a lightweight poncho or raincoat so you can continue your adventure without a hitch.
- Enjoy Nature: Our guides from the Sani community speak Spanish, English and Kichwa and know this forest well. Use their knowledge to spot the rare birds and monkeys that call this park home.
What to pack for Yasuní
Bring whatever you like: the canoe has plenty of space for all your luggage. If you prefer to travel light, you can leave what you don't need in the jungle at our office in Coca, where your guide meets you. Bring:
- Light long-sleeved shirts and long trousers, against sun and mosquitoes
- A rain jacket or poncho
- Insect repellent and sunscreen
- Shoes that may get wet and muddy
- A light sweater for the evenings
- A headlamp or torch
- Binoculars, if you have them
- A refillable water bottle: fresh drinking water is available at the lodge all day
