To characterize how pleasant the weather is in Paris throughout the year, we compute two travel scores. Based on this score, the best time of year to visit Paris for general outdoor tourist activities is from mid June to mid September , with a peak score in the last week of July.
Based on this score, the best time of year to visit Paris for hot-weather activities is from mid July to mid August , with a peak score in the last week of July. For each hour between AM and PM of each day in the analysis period to , independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.
Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.
Our precipitation score , which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0. The growing season in Paris typically lasts for 8.
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. Based on growing degree days alone, the first spring blooms in Paris should appear around April 7 , only rarely appearing before March 22 or after April 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. The brightest month of the year in Paris is June , with an average of 6.
The darker period of the year lasts for 3. The darkest month of the year in Paris is December , with an average of 0. For the purposes of this report, the geographical coordinates of Paris are The topography within 2 miles of Paris contains only modest variations in elevation, with a maximum elevation change of feet and an average elevation above sea level of feet.
Within 10 miles contains only modest variations in elevation feet. Within 50 miles contains significant variations in elevation feet. This report illustrates the typical weather in Paris, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, 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. To get a sense of how much these sources agree with each other, you can view a comparison of Paris and the stations that contribute to our estimates of its temperature history and climate.
Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. All data relating to the Sun's position e. 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 kilometer grid.

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.

Spring Summer Fall Winter. East Oceania All the countries. Climate - France Average weather, temperature, rainfall, when to go, what to pack. Although it is located in a temperate zone, France has different climates : oceanic on the western and northern coasts, transitional in Paris and the north-central region, semi-continental in the eastern region, and Mediterranean in the southern coastal region.
In addition, there are mountainous areas, with a colder climate depending on altitude. The amount of sunshine also varies widely: the sun shines for less than 1, hours a year in Brittany and the far north, for 1, hours in Paris, for about 2, hours in the center-south, and for more than 2, hours along the Mediterranean coast.
Without being particularly hard, the winters are cold. Snow sometimes comes on the heels of rain and the temperature can dip into the negatives, especially in the mountains. Along the Atlantic seaboard, in the West of France, there is an oceanic climate.
Temperature differences are moderate and the winters are mild but damp. It rains relatively frequently. In the East, the climate is continental. Summers are warm, with some thunderstorms, and winters are cold. Temperatures can drop below 0 degrees Celsius and, in the mountains, are frequently accompanied by snow. In the South, the climate is Mediterranean. Summers are hot and winters mild and dry.
