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 Gravesano is decreasing during August, falling from 15% to 6% over the course of the month.
For reference, on July 27, the muggiest day of the year, there are muggy conditions 15% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.
The percentage of time spent at various humidity comfort levels, categorized by dew point.
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.
The average hourly wind speed in Gravesano is essentially constant during August, remaining within 0.1 miles per hour of 3.9 miles per hour throughout.
For reference, on March 31, the windiest day of the year, the daily average wind speed is 4.7 miles per hour, while on October 20, the calmest day of the year, the daily average wind speed is 3.8 miles per hour.
The lowest daily average wind speed during August is 3.8 miles per hour on August 11.

Temperature and Dew Point
There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Gravesano.
The estimated value at Gravesano is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Gravesano and a given station.
The stations contributing to this reconstruction are: Lugano Airport (63%, 4.3 kilometers, south) and Locarno Airport (37%, 15 kilometers, north).
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.
The information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site.
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.
