A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Santa Marta varies significantly throughout the year.
The wetter season lasts 6.3 months, from May 9 to November 17, with a greater than 26% chance of a given day being a wet day. The chance of a wet day peaks at 50% on October 18.
The drier season lasts 5.7 months, from November 17 to May 9. The smallest chance of a wet day is 0% on January 18.
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 50% on October 18.
Daily Chance of Precipitation
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. Santa Marta experiences very significant seasonal variation in monthly rainfall.
The rainy period of the year lasts for 8.5 months, from April 9 to December 24, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around October 14, with an average total accumulation of 5.3 inches.
The rainless period of the year lasts for 3.5 months, from December 24 to April 9. The least rain falls around January 27, with and average total accumulation of 0.0 inches.
Average Monthly Rainfall
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 perceived humidity level in Santa Marta, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 100% throughout.

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 windier part of the year lasts for 5.3 months, from November 25 to May 3, with average wind speeds of more than 6.9 miles per hour. The windiest day of the year is February 26, with an average hourly wind speed of 9.1 miles per hour.
The calmer time of year lasts for 6.7 months, from May 3 to November 25. The calmest day of the year is October 5, with an average hourly wind speed of 4.6 miles per hour.

Temperature and Dew Point
There is only a single weather station, Ernesto Cortissoz International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Santa Marta.
At a distance of 75 kilometers from Santa Marta, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.
The station records are corrected for the elevation difference between the station and Santa Marta according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.
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.
