Ubatuba sees a fairly distinct distribution of precipitation throughout the year, with clear wet and dry seasons. Although rain is possible year-round, its intensity and frequency change noticeably from month to month. Given the tropical climate, all precipitation falls as rain.

The wettest period occurs during the Southern Hemisphere summer months and adjacent periods. January is the rainiest month, with an average of about 9 mm of precipitation and up to 26 rainy days. December and February are also quite humid, with around 8 mm of rainfall and approximately 24 rainy days each. October and November also bring significant precipitation (5-6 mm) and rainy days (20-22), signaling the start of the peak rainy season. During these months, rain occurs frequently, though based on the total volume, it may not be overly heavy.

A drier season sets in Ubatuba from May to July. July stands out as the driest month of the year: total precipitation is only about 2 mm, and the number of rainy days drops to 7. May and June also feature low rainfall (2 mm each) and fewer rainy days (around 11). April (4 mm, 14 rainy days) and August-September (3 mm, 10-12 rainy days) can be considered transitional months, when the frequency and intensity of rain gradually decrease or begin to pick up.

Overall, Ubatuba is characterized by frequent precipitation, especially from October to March. Even in the wettest months, the high number of rainy days is paired with a relatively low total volume of rainfall. This suggests that the rain here is more often persistent and drizzly or short-lived, rather than always being heavy downpours. Nevertheless, when planning your trip, you should account for the high probability of rain, especially during the summer season.

When planning a trip to Ubatuba, it's important to consider its warm and humid tropical climate. Year-round, you'll need light, breathable clothing made from natural fabrics like cotton or linen. Don't forget swimwear, comfortable sandals or flip-flops for the beach, and closed-toe but lightweight shoes for city walks or nature trails. High-SPF sunscreen, a hat or cap, and sunglasses are essential for protection from the strong Brazilian sun. It's also worth bringing insect repellent, especially if you plan on evening walks or visiting areas with lush vegetation.

While the temperature in Ubatuba remains comfortable throughout the year, there are seasonal characteristics that affect your wardrobe choices. The period from October to March, including January and February, is characterized by the highest number of rainy days. During this time, a high-quality umbrella or a light raincoat (poncho) will definitely come in handy, as well as quick-drying clothes. From April to September, especially from June to August, rainfall decreases significantly, and evenings and early mornings can be a bit cooler (average temperatures around 17-19°C). For these occasions, pack a light sweater, fleece, or a long-sleeved shirt. Layering will allow you to easily adapt to any weather changes throughout the day and stay comfortable.
