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 Lugo is increasing during May, rising from 0% to 7% over the course of the month.
For reference, on August 7, the muggiest day of the year, there are muggy conditions 43% 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 Lugo is essentially constant during May, remaining within 0.2 miles per hour of 7.0 miles per hour throughout.
For reference, on March 16, the windiest day of the year, the daily average wind speed is 8.1 miles per hour, while on August 11, the calmest day of the year, the daily average wind speed is 6.2 miles per hour.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
The growing season in Lugo typically lasts for 8.1 months (249 days), from around March 16 to around November 20, rarely starting before February 23 or after April 7, and rarely ending before November 2 or after December 10.
The month of May in Lugo is reliably fully within the growing season.
Time Spent in Various Temperature Bands and the Growing Season in May
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Lugo are increasing during May, increasing by 425°F, from 310°F to 735°F, over the course of the month.

Temperature and Dew Point
There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Lugo.
For each station, the records are corrected for the elevation difference between that station and Lugo 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 Lugo is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Lugo and a given station.
The stations contributing to this reconstruction are: Forlì Airport (44%, 28 kilometers, southeast); Punta Marina (38%, 31 kilometers, east); and Bologna Guglielmo Marconi Airport (18%, 51 kilometers, west).
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.
