The figure below shows you a compact characterization of the entire year of hourly average temperatures. The horizontal axis is the day of the year, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day.

In Āwash, the average percentage of the sky covered by clouds experiences significant seasonal variation over the course of the year.

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

The wetter season lasts 2.6 months, from June 29 to September 16, with a greater than 40% chance of a given day being a wet day. The chance of a wet day peaks at 75% on August 7.

The drier season lasts 9.4 months, from September 16 to June 29. The smallest chance of a wet day is 3% on December 27.

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 75% on August 7.

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 of the year. Āwash experiences extreme seasonal variation in monthly rainfall.

The rainy period of the year lasts for 9.6 months, from January 26 to November 14, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around August 7, with an average total accumulation of 5.3 inches.

The rainless period of the year lasts for 2.4 months, from November 14 to January 26. The least rain falls around December 29, with an average total accumulation of 0.2 inches.

The length of the day in Āwash does not vary substantially over the course of the year, staying within 38 minutes of 12 hours throughout. In 2017, the shortest day is December 21, with 11 hours, 36 minutes of daylight; the longest day is June 21, with 12 hours, 39 minutes of daylight.

The earliest sunrise is at 5:58 AM on May 28, and the latest sunrise is 42 minutes later at 6:40 AM on January 28. The earliest sunset is at 5:55 PM on November 15, and the latest sunset is 48 minutes later at 6:43 PM on July 13.

Daylight saving time (DST) is not observed in Āwash during 2017.

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.

Āwash experiences some seasonal variation in the perceived humidity.

The muggier period of the year lasts for 6.7 months, from March 13 to October 5, during which time the comfort level is muggy, oppressive, or miserable at least 5% of the time. The muggiest day of the year is August 16, with muggy conditions 18% of the time.

The least muggy day of the year is December 27, when muggy conditions are essentially unheard of.

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 predominant average hourly wind direction in Āwash varies throughout the year.

The wind is most often from the east for 2.3 months, from March 11 to May 21 and for 3.3 weeks, from September 22 to October 15, with a peak percentage of 50% on October 2. The wind is most often from the south for 4.0 months, from May 21 to September 22, with a peak percentage of 74% on August 6. The wind is most often from the north for 4.9 months, from October 15 to March 11, with a peak percentage of 82% on January 1.

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 some seasonal variation over the course of the year.

The brighter period of the year lasts for 1.6 months, from February 8 to March 26, with an average daily incident shortwave energy per square meter above 6.9 kWh. The brightest day of the year is March 1, with an average of 7.2 kWh.

The darker period of the year lasts for 1.1 months, from July 6 to August 10, with an average daily incident shortwave energy per square meter below 6.1 kWh. The darkest day of the year is July 23, with an average of 5.8 kWh.

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

Āwash 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 Āwash, 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.
