Weather in September
Temperature
The advent of September sees the average high-temperature at a still warm 29.5°C (85.1°F), subtly shifted from August's 29.3°C (84.7°F). The average low-temperature in Gasmata during September nights is a still warm 23.3°C (73.9°F).Heat index
Throughout September, the heat index is estimated at a sweltering 37°C (98.6°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
