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 Hilton Head is gradually increasing during February, rising from 2% to 4% over the course of the month.

For reference, on July 21, the muggiest day of the year, there are muggy conditions 99% of the time, while on January 30, the least muggy day of the year, there are muggy conditions 2% of the time.

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 Hilton Head typically lasts for 9.9 months (300 days), from around February 18 to around December 15, rarely starting before January 26 or after March 15, and rarely ending before November 22 or after January 5.

The month of February in Hilton Head is very likely fully outside of the growing season, with the chance that a given day is in the growing season very rapidly increasing from 18% to 70% over the course of the month.

Data Sources

This report illustrates the typical weather in Hilton Head, 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 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Hilton Head.

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

The stations contributing to this reconstruction are: Hilton Head Airport (93%, 5.0 kilometers, east); Hunter U. S. Army Airfield (3.8%, 42 kilometers, southwest); and Savannah International Airport (3.6%, 43 kilometers, west).

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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.
