Rainfall

To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.

The average sliding 31-day rainfall during July in Botswana is essentially constant, remaining about 0.1 inches throughout, and rarely exceeding 0.3 inches or falling below -0.0 inches.

The lowest average 31-day accumulation is 0.0 inches on July 29.

Over the course of July in Botswana, the length of the day is gradually increasing. From the start to the end of the month, the length of the day increases by 18 minutes, implying an average daily increase of 36 seconds, and weekly increase of 4 minutes, 10 seconds.

The shortest day of the month is July 1, with 10 hours, 49 minutes of daylight and the longest day is July 31, with 11 hours, 7 minutes of daylight.

The latest sunrise of the month in Botswana is 7:03 AM on July 5 and the earliest sunrise is 6 minutes earlier at 6:57 AM on July 31.

The earliest sunset is 5:52 PM on July 1 and the latest sunset is 12 minutes later at 6:03 PM on July 31.

Daylight saving time is not observed in Botswana during 2026.

For reference, on December 21, the longest day of the year, the Sun rises at 5:37 AM and sets 13 hours, 29 minutes later, at 7:06 PM, while on June 21, the shortest day of the year, it rises at 7:02 AM and sets 10 hours, 47 minutes later, at 5:49 PM.

The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation.

The figure below presents a compact representation of key lunar data for July 2026. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.

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 chance that a given day will be muggy in Botswana is essentially constant during July, remaining around 0% throughout.

For reference, on January 29, the muggiest day of the year, there are muggy conditions 26% of the time, while on May 25, the least muggy day of the year, there are muggy conditions 0% of the time.

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 Botswana is gradually increasing during July, increasing from 6.8 miles per hour to 7.5 miles per hour over the course of the month.

For reference, on October 2, the windiest day of the year, the daily average wind speed is 9.7 miles per hour, while on May 11, the calmest day of the year, the daily average wind speed is 6.3 miles per hour.

The wind direction in Botswana during July is predominantly out of the east from July 1 to July 3 and the north from July 3 to July 31.

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).

While it does not do so every year, freezing temperatures are seen in Botswana over some winters. The day least likely to be in the growing season is July 2, with a 65% chance.

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.

The average accumulated growing degree days in Botswana are increasing during July, increasing by 252°F, from 0°F to 252°F, over the course of the month.

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 in Botswana is gradually increasing during July, rising by 0.6 kWh, from 4.5 kWh to 5.1 kWh, over the course of the month.

For the purposes of this report, the geographical coordinates of Botswana are -22.000 deg latitude, 24.000 deg longitude, and 3,304 ft elevation.

The topography within 2 miles of Botswana is essentially flat, with a maximum elevation change of 46 feet and an average elevation above sea level of 3,165 feet. Within 10 miles is essentially flat (118 feet). Within 50 miles also contains only modest variations in elevation (335 feet).

The area within 2 miles of Botswana is covered by grassland (100%), within 10 miles by grassland (99%), and within 50 miles by grassland (98%).
