Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In South Padre Island, the chance of a wet day over the course of February is essentially constant, remaining around 10% throughout.

For reference, the year's highest daily chance of a wet day is 39% on September 15, and its lowest chance is 9% on February 21.

Probability of Precipitation in February

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 month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.

The average sliding 31-day rainfall during February in South Padre Island is essentially constant, remaining about 0.9 inches throughout, and rarely exceeding 2.3 inches.

The lowest average 31-day accumulation is 0.9 inches on February 13.

Average Monthly Rainfall in February

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

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 South Padre Island is rapidly increasing during February, rising from 23% to 36% over the course of the month.

For reference, on July 16, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 24, the leasy muggy day of the year, there are muggy conditions 20% 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 South Padre Island is essentially constant during February, remaining within 0.1 miles per hour of 7.2 miles per hour throughout.

For reference, on April 26, the windiest day of the year, the daily average wind speed is 7.4 miles per hour, while on September 1, the calmest day of the year, the daily average wind speed is 5.7 miles per hour.

Average Wind Speed in February

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.
The hourly average wind direction in South Padre Island throughout February is predominantly from the south, with a peak proportion of 44% on February 28.

Wind Direction in February

The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions (north, east, south, and west), excluding hours in which the mean wind speed is less than 1 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

Water Temperature

South Padre Island is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

Data Sources

This report illustrates the typical weather in South Padre Island, 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 2 weather stations near enough to contribute to our estimation of the temperature and dew point in South Padre Island.

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

The stations contributing to this reconstruction are: Port Isabel, Port Isabel-Cameron County Airport (69%, 19 kilometers, west) and Brownsville-South Padre Island International Airport (31%, 33 kilometers, southwest).

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.
