In Mumford, the wet season is mostly cloudy, the dry season is partly cloudy, and it is hot and oppressive year round. Over the course of the year, the temperature typically varies from 75°F to 90°F and is rarely below 73°F or above 92°F.

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

The clearer part of the year in Mumford begins around June 25 and lasts for 7.5 months, ending around February 11. On December 22, the clearest day of the year, the sky is clear, mostly clear, or partly cloudy 59% of the time, and overcast or mostly cloudy 41% of the time.

The cloudier part of the year begins around February 11 and lasts for 4.5 months, ending around June 25. On April 25, the cloudiest day of the year, the sky is overcast or mostly cloudy 85% of the time, and clear, mostly clear, or partly cloudy 15% of the time.

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

The wetter season lasts 7.3 months, from March 21 to October 31, with a greater than 40% chance of a given day being a wet day. The chance of a wet day peaks at 76% on June 5.

The drier season lasts 4.7 months, from October 31 to March 21. The smallest chance of a wet day is 3% on December 31.

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 76% on June 5.

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. Mumford experiences extreme seasonal variation in monthly rainfall.

The rainy period of the year lasts for 10 months, from February 9 to December 15, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around June 5, with an average total accumulation of 8.3 inches.

The rainless period of the year lasts for 1.8 months, from December 15 to February 9. The least rain falls around January 13, with an average total accumulation of 0.2 inches.

The length of the day in Mumford does not vary substantially over the course of the year, staying within 25 minutes of 12 hours throughout. In 2017, the shortest day is December 21, with 11 hours, 49 minutes of daylight; the longest day is June 21, with 12 hours, 26 minutes of daylight.

The earliest sunrise is at 5:48 AM on October 24, and the latest sunrise is 31 minutes later at 6:19 AM on February 3. The earliest sunset is at 5:43 PM on November 10, and the latest sunset is 37 minutes later at 6:20 PM on July 17.

Daylight saving time (DST) is not observed in Mumford 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.

The perceived humidity level in Mumford, 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, staying within 4% of 96% 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 average hourly wind speed in Mumford experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 4.5 months, from May 30 to October 16, with average wind speeds of more than 3.9 miles per hour. The windiest day of the year is July 22, with an average hourly wind speed of 4.6 miles per hour.

The calmer time of year lasts for 7.5 months, from October 16 to May 30. The calmest day of the year is December 13, with an average hourly wind speed of 3.2 miles per hour.

The predominant average hourly wind direction in Mumford is from the south throughout the year.

Mumford 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.

The average water temperature experiences some seasonal variation over the course of the year.

The time of year with warmer water lasts for 3.7 months, from February 16 to June 7, with an average temperature above 81°F. The day of the year with the warmest water is May 3, with an average temperature of 83°F.

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 2.7 months, from July 20 to October 12, with an average daily incident shortwave energy per square meter above 5.3 kWh. The brightest day of the year is August 21, with an average of 5.6 kWh.

Temperature and Dew Point

There is only a single weather station, Kotoka International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Mumford.

At a distance of 76 kilometers from Mumford, 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 Mumford 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.

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.
