Weather in September

Temperature

In September, Lagoa experiences a minor shift in meteorological conditions with average high-temperatures marked at a still tropical 31.3°C (88.3°F), closely mirroring the climate in August. During the month of September, the nighttime temperature falls to an average of 25.4°C (77.7°F).

Heat index

During September, the heat index is evaluated at a torrid 37°C (98.6°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
