Weather in Boa Vista

To ensure your journey is as comfortable as possible, familiarise yourself with the current weather situation in the city of Boa Vista. Below, you will find up-to-date reports, temperature charts, and a detailed forecast.

The climate in Boa Vista can be described as hot and tropical, with high temperatures throughout the year. Located in the Northern Hemisphere, the city always welcomes guests with warmth: average thermometer readings steadily hold in the range of +26°C to +29°C. It never gets truly cold here, making this destination ideal for lovers of eternal summer.

Two distinct seasons stand out during the year, differing not so much in temperature as in the amount of rainfall. The dry and hottest period falls on the months from October to March, when the air warms up to +33°C...+34°C, and rain is extremely rare. This is the best time for those who prefer clear and sunny weather for walks and active leisure.

The wet season arrives approximately in April and lasts until September. During this time, especially in May, June, and July, the number of rainy days increases sharply, reaching a maximum. Despite frequent precipitation, the air temperature decreases only slightly, remaining comfortable and warm. Travellers should be prepared for high humidity during this period, but tropical downpours often bring a pleasant freshness.

The climate in Boa Vista is characterised by consistently high temperatures throughout the year, which is typical for the equatorial latitudes of Brazil. There are practically no cold spells here, and the concept of seasonality is quite nominal. The hottest period occurs at the beginning and end of the year: in March and October, average daily highs reach 34°C. During these months, the sun is particularly active, and the air heats up very quickly, creating an atmosphere of true tropical heat.

A cooler period, which locals nominally call winter, occurs from May to July. However, do not expect frost or a sharp drop in temperature: at this time, the daytime temperature becomes more comfortable and mild, dropping to 29°C. Average readings during these months stay at the level of 26°C, making this season favourable for those who do not tolerate the intense heat characteristic of the beginning of the year.

Daily temperature fluctuations in Boa Vista are quite perceptible and bring relief after a hot day. The difference between the daily maximum and the nightly minimum is usually about 8–9 degrees. Nights here are warm and pleasant: even in the "coldest" months, such as July, the air temperature after dark rarely drops below 23°C, and in the hot season, it holds at 25°C.

Precipitation patterns in Boa Vista have a distinct seasonality, which is typical for this part of Brazil. The year can be roughly divided into a period of frequent rains and a drier season. Since the city is located in a hot tropical climate zone, precipitation here falls exclusively as rain; there is no snow or frost.

The wettest period, judging by the frequency of precipitation, falls in the middle of the year — from May to July. During these months, it rains almost daily: the peak is observed in July, when about 29 rainy days are recorded. Despite the high frequency, the total volume of precipitation in millimetres according to the data remains moderate, which may indicate frequent but not overly heavy rains or drizzle.

The dry season is most clearly manifested at the beginning of the year. The "driest" month is February, when the number of days with precipitation drops to a minimum (about 4 days). January and March are also favourable for tourism, offering travellers more sunny days and a low probability of getting caught in the rain. In autumn and at the end of the year, the weather becomes more changeable, with a moderate number of rainy days.

Boa Vista welcomes travellers with warmth all year round, so the foundation of your wardrobe should be light items made from natural fabrics. Cotton and linen are perfect for walking around the city, where the average temperature hovers around +26°C...+29°C. Be sure to bring a wide-brimmed hat or cap, high-quality sunglasses, and cream with a high SPF factor, as the sun in this region of Brazil is very active even on cloudy days.

When packing, it is important to consider the seasonality of rainfall. The period from May to July is characterised by a large number of rainy days (up to 29 days a month), so a light raincoat, a waterproof windbreaker, or a compact umbrella will become indispensable companions. At this time, humidity rises, and it is better to prefer synthetic fabrics that dry quickly, or thin breathable materials. In the drier months, from October to March, rain happens rarely, and the daytime temperature can reach +33°C, so maximally open clothing will be most appropriate.

As for footwear, comfortable breathable trainers or canvas shoes are best suited for exploring city streets and parks, while sandals or sliders are ideal for relaxed leisure. Although there are no severe colds here, a light long-sleeved top may be useful for protection against air conditioning indoors or insects in the evenings. Do not forget to also pack insect repellent in your suitcase, which will ensure comfort during evening walks in the fresh air.
