Weather in September
Temperature
September's arrival shows an average high-temperature of a still hot 32.1°C (89.8°F), hardly different from the previous month. During September, Salap sees a mean low-temperature of 25.8°C (78.4°F).Heat index
The heat index in September is estimated at a life-threatening hot 45°C (113°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Heat index determinations are made taking into account the shade and light air movements. 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 'apparent temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Stay clear of intense sun exposure. Solar protection is of utmost significance. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
