Temperature fluctuations throughout the year are moderate, without extreme peaks of heat or cold, making it an attractive destination to visit.

The summer months, from December to March, are the warmest, with an average air temperature of about 23-25°C.

Average daytime temperatures during this period stay in the range of 26-28°C, and nighttime temperatures rarely drop below 20°C. January and February are the peak of summer, with maximum average temperatures. Although the data indicates a significant number of days with precipitation, the volume of precipitation itself (in mm) is not very large, which may suggest frequent, but not always heavy rains, contributing to a sense of humidity.

Winter, falling in June, July, and August, in Florianopolis is mild and comfortable. Average daytime temperatures fluctuate around 20-21°C, making this period pleasant for walks and active leisure. Nights become cooler, with average minimum temperatures around 12-14°C.

In Florianopolis, there is a distinct seasonality in the distribution of precipitation throughout the year. In general, the summer months are characterized by a higher frequency of rain, while winter brings drier weather. Snow is not characteristic for this region, so all precipitation falls in the form of rain.

The highest number of rainy days falls on the summer period. January is the month with the highest frequency of precipitation, counting an average of 23 rainy days, while the total amount of precipitation is about 8 mm. February, March, and December are also distinguished by frequent rains – from 20 to 21 rainy days in each of these months, with a monthly rainfall norm of 5 to 6 mm. This indicates that it rains regularly in summer, although the total monthly amount remains comparatively low.

The winter months, on the contrary, are significantly drier. July and August are considered the driest, when only about 2 mm of precipitation falls, and the number of rainy days decreases to 7-9 per month. June is also a relatively dry month: about 3 mm of precipitation and approximately 10 rainy days. During this period, rains become a rarer phenomenon.

The off-season – spring (September, October, November) and autumn (April, May) – demonstrates a gradual transition in the nature of precipitation. For example, in April and May, the number of rainy days is 13 and 12 respectively, and the total amount of precipitation is 3-4 mm. With the arrival of spring and the approach of summer, the frequency and volume of precipitation begin to increase: in September, about 14 rainy days (3 mm) are recorded, and in October and November – already about 18 rainy days with 5 mm of precipitation in each, heralding the onset of a wetter season.

When packing a suitcase for a trip to Florianopolis, it is worth considering its warm subtropical climate with distinct humidity and frequent, though not always heavy, precipitation throughout the year. For the summer months (from December to March), when the average temperature stays around 24-25°C, and the maximum reaches 28°C, the ideal choice would be light breathable clothing made of natural fabrics, swimwear, headwear, sunglasses, and high SPF cream. Despite the fact that the amount of precipitation in millimetres may be small, the number of rainy days is significant, especially in January, February, March, and December (20-23 days per month), so a compact raincoat or umbrella will be very useful.

In the cooler months, from June to August, the average temperature drops to 16-17°C, and the minimum can reach 12-14°C, especially in the evenings. During this period, it is recommended to bring clothing based on the principle of layering: T-shirts, long-sleeved shirts, a light jacket or fleece, as well as trousers. Although this is a drier season (7-10 rainy days per month), light protection from rain will still not be amiss. Regardless of the time of year, comfortable walking shoes for the diverse landscapes of Florianopolis, from beaches to city streets, are an absolute necessity.
