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 chance that a given day will be muggy in Inverness is rapidly increasing during April, rising from 4% to 15% over the course of the month.

For reference, on July 24, the muggiest day of the year, there are muggy conditions 96% of the time, while on January 23, the least muggy day of the year, there are muggy conditions 0% of the time.

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 Inverness is essentially constant during April, remaining within 0.2 miles per hour of 4.3 miles per hour throughout.

For reference, on February 26, the windiest day of the year, the daily average wind speed is 4.7 miles per hour, while on August 5, the calmest day of the year, the daily average wind speed is 3.0 miles per hour.

Growing Season

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 Inverness typically lasts for 8.1 months (250 days), from around March 12 to around November 17, rarely starting before February 15 or after April 2, and rarely ending before October 28 or after December 9.

The month of April in Inverness is more likely than not fully within the growing season, with the chance that a given day is in the growing season increasing from 89% to 100% over the course of the month.

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 Inverness are increasing during April, increasing by 425°F, from 556°F to 981°F, over the course of the month.

Data Sources

This report illustrates the typical weather in Inverness 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 Inverness.

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

The stations contributing to this reconstruction are: Troy Municipal Airport (51%, 30 kilometers, southwest); Weedon Field (19%, 59 kilometers, east); Auburn University Automatic Meteorological Observing System (15%, 69 kilometers, north); and Maxwell Air Force Base / Montgomery (15%, 70 kilometers, northwest).

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.

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.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
