Weather in September
Temperature
The arrival of September records an average high-temperature of a warm 29.5°C (85.1°F), closely related to the 30.2°C (86.4°F) observed in August. During the month of September, Jamapa's average nighttime temperature closely mirrors its daytime counterpart, at 24.7°C (76.5°F).Heat index
In September, the average heat index is evaluated at a torrid 36°C (96.8°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

The months with the highest UV index are March through September, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.Note: The daily maximum UV index of 7 in September interprets into the following advice:
Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
