October stands out as Piratininga's warmest month, with temperatures ranging between an average high of 29.7°C (85.5°F) and a low of 18°C (64.4°F).

Heat index

The heat index value during October is evaluated at a very hot 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
