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 Welshpool, 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, remaining a virtually constant 0% throughout.

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 Welshpool experiences significant seasonal variation over the course of the year.

The windier part of the year lasts for 5.1 months, from October 28 to March 30, with average wind speeds of more than 11.2 miles per hour. The windiest day of the year is January 6, with an average hourly wind speed of 13.2 miles per hour.

The calmer time of year lasts for 6.9 months, from March 30 to October 28. The calmest day of the year is August 3, with an average hourly wind speed of 9.2 miles per hour.

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 extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3.4 months, from May 3 to August 15, with an average daily incident shortwave energy per square meter above 5.2 kWh. The brightest day of the year is July 1, with an average of 6.3 kWh.

Data Sources

This report illustrates the typical weather in Welshpool, 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 7 weather stations near enough to contribute to our estimation of the temperature and dew point in Welshpool.

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

The stations contributing to this reconstruction are: RAF Shawbury (45%, 36 kilometers, northeast); Hawarden (21%, 59 kilometers, north); Aberporth (8%, 113 kilometers, southwest); Royal Air Force Valley (8%, 114 kilometers, northwest); St Athan Royal Air Force Base (6%, 141 kilometers, south); Cardiff Airport (6%, 141 kilometers, south); and Bristol Airport (6%, 145 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.

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .

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.
