A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Amsterdam varies throughout the year.
The wetter season lasts 204 days, from July 14 to February 3, with a greater than 30% chance of a given day being a wet day. The chance of a wet day peaks at 38% on December 23.
The drier season lasts 161 days, from February 3 to July 14. The smallest chance of a wet day is 22% on April 30.
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 36% on December 23.
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. Amsterdam experiences some seasonal variation in monthly rainfall.
Rain falls throughout the year in Amsterdam. The most rain falls during the 31 days centered around December 25, with an average total accumulation of 2.4 inches.
The least rain falls around April 20, with and average total accumulation of 1.2 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.
The perceived humidity level in Amsterdam, 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 Amsterdam experiences mildly seasonal variation over the course of the year.
The windier part of the year lasts for 168 days, from October 10 to March 27, with average wind speeds of more than 6.9 miles per hour. The windiest day of the year is January 6, with an average hourly wind speed of 8.3 miles per hour.
The calmer time of year lasts for 197 days, from March 27 to October 10. The calmest day of the year is August 4, with an average hourly wind speed of 5.5 miles per hour.
Average Wind Speed
The predominant average hourly wind direction in Amsterdam varies throughout the year.
The wind is most often from the south for 12 days, from January 2 to January 14 and for 73 days, from October 1 to December 13, with a peak percentage of 38% on October 31. The wind is most often from the west for 93 days, from January 14 to April 17; for 143 days, from May 11 to October 1; and for 20 days, from December 13 to January 2, with a peak percentage of 45% on July 3.

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 very significant seasonal variation over the course of the year.
The brighter period of the year lasts for 110 days, from April 29 to August 17, with an average daily incident shortwave energy per square meter above 5.3 kWh. The brightest day of the year is June 27, with an average of 6.5 kWh.

This report illustrates the typical weather in Amsterdam, 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 Amsterdam.
For each station, the records are are corrected for the elevation difference between that station and Amsterdam 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 Amsterdam is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Amsterdam and a given station.
The stations contributing to this reconstruction are: Amsterdam Airport Schiphol (73%, 11 kilometers, southwest), De Bilt (12%, 36 kilometers, southeast), Lelystad Airport (9%, 44 kilometers, east), and De Kooy (6%, 62 kilometers, north).
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.
