Weather in September
Temperature
Dossman registers an average high-temperature of a still tropical 87.3°F (30.7°C) with the arrival of September, showing minor deviation from the preceding month. Dossman experiences a consistent average temperature of 68.9°F (20.5°C) throughout the nights in September.Heat index
September's mean heat index is estimated at a sweltering 102.2°F (39°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 hold great significance to 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.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
