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.

Marsa Alam experiences some seasonal variation in the perceived humidity.

The muggier period of the year lasts for 4.3 months, from July 24 to December 1, during which time the comfort level is muggy, oppressive, or miserable at least 7% of the time. The muggiest day of the year is October 16, with muggy conditions 26% of the time.

The least muggy day of the year is February 19, with muggy conditions 1% 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 Marsa Alam experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 1.4 months, from May 19 to June 30, with average wind speeds of more than 6.0 miles per hour. The windiest day of the year is June 9, with an average hourly wind speed of 6.8 miles per hour.

The calmer time of year lasts for 11 months, from June 30 to May 19. The calmest day of the year is October 25, with an average hourly wind speed of 5.3 miles per hour.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences significant seasonal variation over the course of the year.

The brighter period of the year lasts for 3.8 months, from April 30 to August 24, with an average daily incident shortwave energy per square meter above 7.5 kWh. The brightest day of the year is June 19, with an average of 8.4 kWh.

Data Sources

This report illustrates the typical weather in Marsa Alam, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Marsa Alam is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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.

The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Marsa Alam, according to the International Standard Atmosphere .

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.

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.
