Planning your day or getting ready for a trip? Here you will find the most up-to-date weather information for Óbidos, including current conditions and detailed forecasts.

The climate in Óbidos can be described as hot and tropical, typical of the Amazon region. Eternal summer reigns here: air temperatures remain remarkably stable throughout the year, averaging from 26°C to 30°C. Travelers should be prepared for warmth and high humidity, regardless of the month chosen for their trip.

Instead of the usual four seasons, the weather here is divided into wetter and relatively dry seasons. From January to May, there is a period of frequent precipitation when rain can fall almost daily, refreshing the air and nourishing the local nature. During this time, the temperature stays at a comfortable level around 26-27°C, and nature appears in all its glory.

Starting from July and through November, the number of rainy days significantly decreases, reaching a minimum in August and September. It is during this "dry" period that the air heats up the most, and daytime temperatures often exceed 30°C. This time is great for those who prefer sunny weather and plan active walks around the city and its surroundings.

The climate in Óbidos is remarkably stable: eternal summer reigns here, typical of the Amazon region of Brazil. The annual temperature cycle is smooth, without sharp jumps or pronounced cold snaps. The hottest period of the year is from September to October, when the average air temperature reaches its peak at around 29.7°C. During this time, the daytime heat can be quite intense, with maximum readings reaching 33.2°C.

Even during the months that could formally be called "cooler" (mainly the first half of the year, from January to May), the weather remains very warm. Average values during this period stay at 26.7°C — 26.9°C. Daytime highs during this time rarely drop below 29°C, but due to more frequent precipitation and cloud cover, the heat is slightly easier to tolerate than in the dry season of the second half of the year.

Diurnal temperature fluctuations in Óbidos are moderate, providing comfortable conditions for evening relaxation. The difference between daytime heat and nighttime coolness is usually about 4–7 degrees. The nights here are very warm and mild: minimum air temperatures stay stable in the 24–26°C range all year round, so you are unlikely to need warm clothes.

The climate of Óbidos is characterized by pronounced seasonality in the distribution of precipitation. Since the city is located in Brazil's tropical belt, it only rains here, and there is no snow. The wettest period occurs in the first half of the year: from January to May, precipitation falls almost every day. Statistics show that between 26 and 28 rainy days are recorded during these months, so an umbrella or raincoat is a must-have in your luggage.

The situation changes noticeably in the second half of the year when the drier season arrives. The driest months are August and September: the number of days with precipitation decreases to a minimum (about 7 days per month), and the volume of rainfall becomes insignificant. This time is considered the most favorable for tourists who prefer stable and clear weather.

The transition period begins in October and November, when the frequency of rain starts to gradually increase again, reaching 17–24 rainy days by the end of the year. Despite the high humidity in certain seasons, the rain often refreshes the air, which helps in better tolerating the high temperatures typical of this region.

When preparing for a trip to Óbidos, you should plan for the hot and humid climate typical of this region of Brazil. Since the average air temperature stays stable in the 26–30°C range throughout the year, the core of your luggage should consist of light, loose clothing made from natural breathable fabrics such as cotton and linen. Be sure to bring comfortable shoes: sandals are suitable for leisurely strolls around town, while closed light sneakers will be useful for longer excursions.

Pay special attention to sun and rain protection. From December to May, the number of rainy days is high (up to 28 days per month), so a compact raincoat, waterproof windbreaker, or umbrella will be your best friends. In the drier and hotter months, such as September and October, when temperatures can reach 33°C, it is critical to have a head covering, high-quality sunglasses, and sunscreen with a high SPF to avoid sunburn.

Don't forget the specifics of the tropical climate: high humidity and proximity to water can mean insects, so repellents should be in your first-aid kit. It is also recommended to pack a couple of lightweight long-sleeved items—they will come in handy for protection against mosquitoes in the evening and for preventing sunburn during daytime trips. A reusable water bottle will help you stay hydrated while exploring picturesque Óbidos.
