Weather in October
Temperature
During October and November, São José de Piranhas experiences its highest average temperatures, peaking at 34.3°C (93.7°F).Heat index
Throughout October, the heat index is evaluated at a sweltering 39°C (102.2°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold great significance to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
