Weather in September
Temperature
Ruku's September is marked by a high-temperature average of a still tropical 32.3°C (90.1°F), unchanged from the previous month. During the September nights, Ruku's temperature maintains an average close to the daytime highs, settling at a warm 27.7°C (81.9°F).Heat index
For most parts of September, the heat index is appraised at a blistering 40°C (104°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index data is primarily for areas with shade and subjected to light winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
