Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Maastricht varies throughout the year.

The wetter season lasts 243 days, from May 20 to January 18, with a greater than 31% chance of a given day being a wet day. The chance of a wet day peaks at 36% on December 23.

The drier season lasts 122 days, from January 18 to May 20. The smallest chance of a wet day is 25% on April 10.

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 34% on June 12.

Daily Chance of Precipitation

The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day).

Rainfall

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. Maastricht experiences some seasonal variation in monthly rainfall.

Rain falls throughout the year in Maastricht. The most rain falls during the 31 days centered around December 23, with an average total accumulation of 2.2 inches.

The least rain falls around April 19, with and average total accumulation of 1.5 inches.

Average Monthly Rainfall

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

Humidity

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 Maastricht, 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 1% of 1% throughout.

Wind

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 Maastricht experiences mildly seasonal variation over the course of the year.

The windier part of the year lasts for 170 days, from October 15 to April 3, with average wind speeds of more than 5.7 miles per hour. The windiest day of the year is January 7, with an average hourly wind speed of 7.0 miles per hour.

The calmer time of year lasts for 195 days, from April 3 to October 15. The calmest day of the year is August 5, with an average hourly wind speed of 4.5 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Maastricht varies throughout the year.

The wind is most often from the west for 241 days, from January 31 to September 29, with a peak percentage of 47% on July 7. The wind is most often from the south for 124 days, from September 29 to January 31, with a peak percentage of 47% on October 31.

The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

Solar Energy

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 112 days, from April 29 to August 19, with an average daily incident shortwave energy per square meter above 5.2 kWh. The brightest day of the year is June 26, with an average of 6.4 kWh.

The darker period of the year lasts for 114 days, from October 27 to February 18, with an average daily incident shortwave energy per square meter below 1.8 kWh. The darkest day of the year is December 23, with an average of 0.6 kWh.

Data Sources

This report illustrates the typical weather in Maastricht, 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 Maastricht.

For each station, the records are corrected for the elevation difference between that station and Maastricht 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 Maastricht is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Maastricht and a given station.

The stations contributing to this reconstruction are: Maastricht Aachen Airport (56%, 9 kilometers, northeast), Genk (30%, 16 kilometers, northwest), Liège Airport (10%, 29 kilometers, southwest), and Spa-La Sauvenière Airport (4.1%, 44 kilometers, south).

Other Data

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.
