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 59% on July 28.

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).

Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day in the year. Destin experiences significant seasonal variation in monthly rainfall.

Rain falls throughout the year in Destin. The most rain falls during the 31 days centered around July 22, with an average total accumulation of 5.8 inches.

The least rain falls around May 12, with and average total accumulation of 3.3 inches.

Average Monthly Rainfall

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.

Destin experiences very significant seasonal variation in the perceived humidity.

The muggier period of the year lasts for 198 days, from April 14 to October 29, during which time the comfort level is muggy, oppressive, or miserable at least 28% of the time. The muggiest day of the year is August 6, with muggy conditions 99% of the time.

The least muggy day of the year is January 31, with muggy conditions 4% 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 Destin experiences mildly seasonal variation over the course of the year.

The windier part of the year lasts for 219 days, from September 24 to May 1, with average wind speeds of more than 4.5 miles per hour. The windiest day of the year is January 22, with an average hourly wind speed of 5.5 miles per hour.

The calmer time of year lasts for 146 days, from May 1 to September 24. The calmest day of the year is August 9, with an average hourly wind speed of 3.5 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

Data Sources

This report illustrates the typical weather in Destin, 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 Destin.

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

The stations contributing to this reconstruction are: Destin Executive Airport (86%, 2.4 kilometers, east), Destin–Fort Walton Beach Airport (10%, 10 kilometers, north), and Hurlburt Field (4.3%, 18 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 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.
