We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
The chance that a given day will be muggy in Freguesia do Ribeirao da Ilha is gradually decreasing during July, falling from 6% to 4% over the course of the month.
The lowest chance of a muggy day during July is 3% on July 23.
For reference, on February 12, the muggiest day of the year, there are muggy conditions 92% of the time, while on July 23, the least muggy day of the year, there are muggy conditions 3% of the time.

Temperature and Dew Point
There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Freguesia do Ribeirao da Ilha.
For each station, the records are corrected for the elevation difference between that station and Freguesia do Ribeirao da Ilha according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Freguesia do Ribeirao da Ilha is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Freguesia do Ribeirao da Ilha and a given station.
The stations contributing to this reconstruction are: Florianópolis-Hercílio Luz International Airport (99%, 5.5 kilometers, north) and Diomício Freitas/Forquilhinha Airport (0.8%, 141 kilometers, southwest).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.
Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.
We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
