Weather in September
Temperature
The transition from August to September sees an average high-temperature of a warm 85.1°F (29.5°C), indicating a minor variance from the prior month. Nighttime temperatures during September report a consistent average of 80.1°F (26.7°C).Heat index
The heat index for September is evaluated at a torrid 95°F (35°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear. Be careful! The Sun's UV radiation is accentuated by reflecting off sand and water.
