Weather in September
Temperature
Entering September, Al Qatif's average high-temperature reads a sweltering 38.9°C (102°F), indicating a close resemblance to the previous month's climate. September nights in Al Qatif observe an average temperature dip to a hot 31.5°C (88.7°F).Heat index
September's heat index is appraised at a life-threatening hot 47°C (116.6°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.Evaluating the heat index requires understanding its values in the shade and with gentle winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive 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. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
