The month of July in Mauritius experiences essentially constant cloud cover, with the percentage of time that the sky is overcast or mostly cloudy remaining about 12% throughout the month.

The clearest day of the month is July 1, with clear, mostly clear, or partly cloudy conditions 88% of the time.

For reference, on February 4, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 60%, while on September 9, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 89%.

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Mauritius, the chance of a wet day over the course of July is essentially constant, remaining around 5% throughout.

For reference, the year's highest daily chance of a wet day is 33% on February 10, and its lowest chance is 4% on July 14.

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 Mauritius is essentially constant, remaining about 0.4 inches throughout, and rarely exceeding 0.9 inches.

Over the course of July in Mauritius, the length of the day is gradually increasing. From the start to the end of the month, the length of the day increases by 17 minutes, implying an average daily increase of 33 seconds, and weekly increase of 3 minutes, 52 seconds.

The shortest day of the month is July 1, with 10 hours, 55 minutes of daylight and the longest day is July 31, with 11 hours, 12 minutes of daylight.

The latest sunrise of the month in Mauritius is 6:46 AM on July 5 and the earliest sunrise is 6 minutes earlier at 6:40 AM on July 31.

The earliest sunset is 5:41 PM on July 1 and the latest sunset is 11 minutes later at 5:52 PM on July 31.

Daylight saving time is not observed in Mauritius during 2024.

For reference, on December 21, the longest day of the year, the Sun rises at 5:26 AM and sets 13 hours, 22 minutes later, at 6:48 PM, while on June 20, the shortest day of the year, it rises at 6:44 AM and sets 10 hours, 54 minutes later, at 5:38 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 2024. 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 Mauritius is decreasing during July, falling from 29% to 23% over the course of the month.

For reference, on February 1, the muggiest day of the year, there are muggy conditions 100% of the time, while on August 18, the least muggy day of the year, there are muggy conditions 19% 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 Mauritius is gradually increasing during July, increasing from 16.8 miles per hour to 17.6 miles per hour over the course of the month.

For reference, on July 25, the windiest day of the year, the daily average wind speed is 17.7 miles per hour, while on November 26, the calmest day of the year, the daily average wind speed is 13.0 miles per hour.

The highest daily average wind speed during July is 17.7 miles per hour on July 25.

The hourly average wind direction in Mauritius throughout July is predominantly from the east, with a peak proportion of 89% on July 31.

Mauritius 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 surface water temperature in Mauritius is essentially constant during July, remaining within 1°F of 75°F throughout.

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).

Temperatures in Mauritius are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.

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 Mauritius are rapidly increasing during July, increasing by 620°F, from 1°F to 621°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 Mauritius is essentially constant during July, remaining within 0.2 kWh of 4.4 kWh throughout.

For the purposes of this report, the geographical coordinates of Mauritius are -20.300 deg latitude, 57.583 deg longitude, and 0 ft elevation.

The topography within 2 miles of Mauritius is essentially flat, with a maximum elevation change of 0 feet and an average elevation above sea level of 0 feet. Within 10 miles is also essentially flat (0 feet). Within 50 miles is also essentially flat (0 feet).

The area within 2 miles of Mauritius is covered by cropland (52%), trees (25%), and grassland (13%), within 10 miles by cropland (49%) and trees (27%), and within 50 miles by water (91%).
