A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Paris varies throughout the year.
The wetter season lasts 10 months, from March 30 to February 3, with a greater than 25% chance of a given day being a wet day. The chance of a wet day peaks at 30% on May 23.
The drier season lasts 1.9 months, from February 3 to March 30. The smallest chance of a wet day is 20% on March 3.
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 30% on May 23.

Sunrise & Sunset with Twilight and Daylight Saving Time
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 perceived humidity level in Paris, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, staying within 2% of 2% throughout.
Humidity Comfort Levels
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 Paris experiences mild seasonal variation over the course of the year.
The windier part of the year lasts for 6.2 months, from October 13 to April 19, with average wind speeds of more than 5.3 miles per hour. The windiest day of the year is January 16, with an average hourly wind speed of 6.3 miles per hour.
The calmer time of year lasts for 5.8 months, from April 19 to October 13. The calmest day of the year is August 8, with an average hourly wind speed of 4.2 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Paris varies throughout the year.
The wind is most often from the west for 2.1 months, from February 1 to April 5 and for 3.7 months, from June 8 to September 28, with a peak percentage of 42% on July 6.

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.
The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.
The brighter period of the year lasts for 3.5 months, from May 4 to August 21, with an average daily incident shortwave energy per square meter above 5.4 kWh. The brightest day of the year is June 26, with an average of 6.6 kWh.

This report illustrates the typical weather in Paris, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Paris.
For each station, the records are corrected for the elevation difference between that station and Paris 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 Paris is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Paris and a given station.
The stations contributing to this reconstruction are: Vélizy – Villacoublay Air Base (23%, 14 kilometers, southwest); Paris Orly Airport (34%, 14 kilometers, south); Paris–Le Bourget Airport (34%, 15 kilometers, northeast); and Pontoise – Cormeilles Aerodrom (9%, 35 kilometers, northwest).
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.
