A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Faro varies throughout the year.
The wetter season lasts 7.1 months, from October 3 to May 7, with a greater than 13% chance of a given day being a wet day. The chance of a wet day peaks at 25% on December 14.
The drier season lasts 4.9 months, from May 7 to October 3. The smallest chance of a wet day is 0% on July 25.
Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 25% on December 14.
Daily Chance of Precipitation
To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Faro experiences significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 8.5 months, from September 10 to May 27, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around November 8, with an average total accumulation of 3.2 inches.
The rainless period of the year lasts for 3.4 months, from May 27 to September 10. The least rain falls around July 25, with and average total accumulation of 0.0 inches.
Average Monthly Rainfall
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.
Faro experiences some seasonal variation in the perceived humidity.
The muggier period of the year lasts for 4.6 months, from June 14 to November 3, during which time the comfort level is muggy, oppressive, or miserable at least 7% of the time. The muggiest day of the year is September 6, with muggy conditions 28% of the time.
The least muggy day of the year is February 20, when muggy conditions are essentially unheard of.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Faro.
For each station, the records are corrected for the elevation difference between that station and Faro 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 Faro is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Faro and a given station.
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.
