Temperature

September's advent notes a subtle adjustment in average high-temperature to a still warm 29.5°C (85.1°F) from August. The temperature in Jonha lowers to an average of 22.5°C (72.5°F) during September nights.

Heat index

The average heat index in September is computed to be a very hot 37°C (98.6°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Humidity

The average relative humidity in September is 83%.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Always opt for UVA and UVB-resistant sunglasses on radiant days.
