Aracatuba is characterized by a typical tropical climate with a clear division of the year into wet and dry seasons. Overall, the weather here remains warm or hot throughout all twelve months, making the city an attractive destination for sun lovers. The climate is quite predictable, allowing you to easily plan your trip based on the seasonal features of the region.

The most pronounced seasons are the wet summer and the dry winter. From December to March, heat reigns in the city: daytime temperatures often exceed +30°C, and frequent tropical downpours (up to 20 rainy days per month) bring high humidity. Winter, which lasts from June to August in the Southern Hemisphere, is conversely distinguished by very dry weather with minimal rainfall. During this period, days remain warm and clear, but nights become noticeably cooler, when the thermometer can drop to +16°C.

A notable feature of the local climate is the sharp jump in temperatures during the spring period. September and October often become the hottest months of the year, when the maximum temperature can reach +33°C, while the rainy season is only just beginning to gain strength. Tourists heading to this region of Brazil should consider these fluctuations: a light jacket will be useful for winter evenings, and a reliable umbrella for a summer visit.

Aracatuba is distinguished by a hot climate with quite pronounced seasonal changes in the temperature regime. The hottest period here begins in spring and continues throughout the summer: from September to March, daytime highs consistently exceed the +30°C mark.

The summer months (December, January, and February) are characterized by stable heat: during the day the air warms up to +31°C, and nights remain sultry and warm, with temperatures not lower than +22...+23°C.

July usually becomes the coldest month: night temperatures can fall to +15.9°C, creating a noticeable contrast with the daytime warmth, which even in winter holds at the level of +27...+28°C.

When planning a journey to Aracatuba, it is important to consider the pronounced seasonality of precipitation. This region is characterized by a clear division of the year into wet and dry periods. The highest probability of encountering rain exists in the summer months (which in the Southern Hemisphere fall on the period from December to March). At this time, an umbrella will become your mandatory companion.

The peak of the wet season falls on January, when precipitation can occur during 20 days of the month. December and February are also distinguished by a high frequency of rain — about 17–18 days with precipitation. However, judging by average indicators, although the rains here are frequent, they are not too heavy in terms of water volume, which is often typical for tropical showers.

If you prefer dry and clear weather, the best time for a visit is the Brazilian winter. The period from June to August is characterized by a minimal amount of rainfall. The driest month is July, when statistically only one rainy day is recorded, and the precipitation level tends towards zero. May and September serve as transitional months, when rains happen extremely rarely (only 3 days per month).

When preparing for a trip to Aracatuba, primarily give preference to light and breathable clothing. Since the climate here is predominantly warm, items made from natural cotton or linen are ideal. From October to March, the temperature during the day often exceeds 30°C, and it rains quite often, especially in January and February. During this period, a compact umbrella or a light raincoat, as well as comfortable, quick-drying footwear, will definitely be useful to you.

If your journey falls on the "winter" months from May to August, be prepared for the fact that evenings can be cool: the temperature sometimes drops to 16–17°C. For this time of year, the principle of layering works best: take a light sweater, hoodie, or denim jacket with you, which can be thrown over a t-shirt after sunset. This season is distinguished by dryness, so serious protection from moisture is unlikely to be required.

Regardless of the season, the sun in this part of Brazil can be very active, especially in September, when temperature maximums are recorded. A wide-brimmed hat or cap, high-quality sunglasses, and cream with a high SPF level should be in your suitcase at any time of the year. It will also be useful to bring repellents to ensure comfort during evening walks.
