July weather forecast
Niamey, Niger

July showcases Niamey in a full-blown wet season mode. The temperature readouts plateau, providing relief from the constant escalation of the preceding months. The impressive rainfall and frequency of rainy days make it evident that the city is at the peak of its wet season. A cloudy cover hangs over the city, as shown by the 23% cloud coverage, promising relief from the scorching sun. This time of the year the winds continue to blow at a mean speed of 14.7km/h (9.1mph), corresponding with the winds experienced in January.

Temperature

The transition to July results in a modest reduction in average high-temperature, moving from a fiery hot 39.8°C (103.6°F) in June to a still torrid 36.8°C (98.2°F). Niamey records an average low of 28.2°C (82.8°F) throughout the nights in July.

Heat index

The heat index for July is calculated to be a blistering 43°C (109.4°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Note: A daily high UV index of 8 in July leads to these guidelines:
Being unprotected puts skin and eyes at risk of rapid damage. Always be safe. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Experience reduced UV exposure by about half when donning a wide-brim hat.
