Weather in September
Temperature
The dawn of September sees an average high-temperature of a still tropical 31.5°C (88.7°F), subtly contrasting with August's 32.8°C (91°F). In September, the recorded average low-temperature in Guayacanes is a moderately hot 23.7°C (74.7°F).Heat index
In September, the heat index is computed to be an extremely hot 43°C (109.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
