The commencement of September introduces an average high-temperature of a still hot 30.6°C (87.1°F), closely mirroring the preceding month. Jantho throughout September, records an average low-temperature of 24.5°C (76.1°F).Heat index
During September, the heat index is calculated to be a very hot 38°C (100.4°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Be advised! The UV radiation from the Sun can be almost doubled due to the reflective properties of snow.
