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 Amsterdam is essentially constant during April, remaining around 0% throughout.
For reference, on July 18, the muggiest day of the year, there are muggy conditions 4% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time.

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 is gradually decreasing during April, decreasing from 6.8 miles per hour to 6.1 miles per hour over the course of the month.
For reference, on January 6, the windiest day of the year, the daily average wind speed is 8.3 miles per hour, while on August 4, the calmest day of the year, the daily average wind speed is 5.5 miles per hour.

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 in Amsterdam is rapidly increasing during April, rising by 1.6 kWh, from 3.7 kWh to 5.3 kWh, over the course of the month.

This report illustrates the typical weather in Amsterdam year round, 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 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.
