September weather forecast
Katsina, Nigeria

By September, Katsina witnesses a noticeable shift from the rainy season to drier weather. The number of rainy days dwindles, and the amount of precipitation experiences a significant drop. Atmospheric pressure begins to rise again. Despite the tapering rainfall, the high humidity levels persist. A drastic decrease in rainfall to 40mm (1.57") marks the retreat of the peak rainy season.

Temperature

In September, the average high-temperature registers at a still tropical 34.6°C (94.3°F), nearly identical to August's 32°C (89.6°F). Throughout September, the temperature falls to an average low of 24.8°C (76.6°F).

Heat index

September's average heat index is calculated to be an extremely hot 41°C (105.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Note: A typical high UV index of 8 in September suggests the following recommendations:
Always remain cautious. Unprotected skin and eyes are prone to swift harm. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
