Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Cairo varies significantly throughout the year.

The wetter season lasts 3.3 months, from May 29 to September 8, with a greater than 38% chance of a given day being a wet day. The chance of a wet day peaks at 59% on July 30.

The drier season lasts 8.7 months, from September 8 to May 29. The smallest chance of a wet day is 16% on October 30.

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 30.

The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The transitions to and from daylight saving time are indicated by the 'DST' labels.

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.

Cairo experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 5.6 months, from May 4 to October 23, during which time the comfort level is muggy, oppressive, or miserable at least 26% of the time. The muggiest day of the year is July 25, with muggy conditions 98% of the time.

The least muggy day of the year is January 24, with muggy conditions 2% 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 Cairo experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 7.6 months, from September 23 to May 12, with average wind speeds of more than 5.6 miles per hour. The windiest day of the year is February 26, with an average hourly wind speed of 6.8 miles per hour.

The calmer time of year lasts for 4.4 months, from May 12 to September 23. The calmest day of the year is August 8, with an average hourly wind speed of 4.4 miles per hour.

Best Time of Year to Visit

To characterize how pleasant the weather is in Cairo throughout the year, we compute two travel scores.

The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Based on this score, the best times of year to visit Cairo for general outdoor tourist activities are from early April to late May and from late September to late October, with a peak score in the last week of April.

The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. Based on this score, the best times of year to visit Cairo for hot-weather activities are from mid May to early July and from mid August to early October, with a peak score in the second week of September.

Methodology

For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.

Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.

Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more.

Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter.

Our beach/pool temperature score is 0 for perceived temperatures below 65°F, rising linearly to 9 for 75°F, to 10 for 82°F, falling linearly to 9 for 90°F, and to 1 for 100°F or hotter.

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 Cairo typically lasts for 9.5 months (288 days), from around February 20 to around December 5, rarely starting before January 29 or after March 16, and rarely ending before November 7 or after December 29.

Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.

Based on growing degree days alone, the first spring blooms in Cairo should appear around January 18, only rarely appearing before January 10 or after January 30.

Data Sources

This report illustrates the typical weather in Cairo, 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 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Cairo.

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

The stations contributing to this reconstruction are: Thomasville Regional Airport (44%, 31 kilometers, east); Decatur County Industrial Air Park (27%, 43 kilometers, west); Tallahassee Regional Airport (18%, 56 kilometers, south); and Southwest Georgia Regional Airport (12%, 73 kilometers, north).

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.

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .

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.
