Weather in September
Temperature
September registers an average high-temperature of a still tropical 31.7°C (89.1°F), slightly varied from August's 30.3°C (86.5°F). During September, Rijau experiences a consistent low-temperature average of 23.6°C (74.5°F).Heat index
In September, the heat index is calculated to be a scorching 41°C (105.8°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Heat index details are generally centered around shaded locations and a mild breeze. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Enhance your sun protection with tightly woven, yet airy clothing.
