The transition into September marks the average high-temperature at a still moderately hot 29.5°C (85.1°F), differing minimally from August's 29.2°C (84.6°F). Katugastota anticipates an average minimum temperature of 21.1°C (70°F) in the month of September.

Heat index

Throughout September, the heat index is computed to be a fiery hot 35°C (95°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Know that the heat index computations account for shaded terrains and slight winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. 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 highly important for children. 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 evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Persist in precautions and follow sun safety policies. Keeping sunburn at bay is imperative. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
