Precipitation

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

The wetter season lasts 229 days, from April 3 to November 18, with a greater than 25% chance of a given day being a wet day. The chance of a wet day peaks at 36% on May 9.

The drier season lasts 136 days, from November 18 to April 3. The smallest chance of a wet day is 15% on February 8.

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 May 9.

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).

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.

Milano Malpensa Airport experiences significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 90 days, from June 13 to September 11, during which time the comfort level is muggy, oppressive, or miserable at least 8% of the time. The muggiest day of the year is July 28, with muggy conditions 30% of the time.

The least muggy day of the year is December 3, when muggy conditions are essentially unheard of.

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 at Milano Malpensa Airport does not vary significantly over the course of the year, remaining within 0.4 miles per hour of 2.4 miles per hour throughout.

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 98 days, from May 13 to August 19, with an average daily incident shortwave energy per square meter above 5.9 kWh. The brightest day of the year is July 6, with an average of 7.1 kWh.

The darker period of the year lasts for 110 days, from October 25 to February 12, with an average daily incident shortwave energy per square meter below 2.6 kWh. The darkest day of the year is December 16, with an average of 1.4 kWh.

Data Sources

This report illustrates the typical weather at Milano Malpensa Airport, 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

Milano Malpensa Airport has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required.

In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations.

The stations on which we may fall back include but are not limited to Novara / Cameri, Lugano Airport, Locarno Airport, Milano Linate Airport, Il Caravaggio International Airport, Pian Rosa, Turin Caselle Airport, and Torino / Bric Della Croce.

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.
