Temperature

The average high-temperature in January, at a still hot 31.8°C (89.2°F), reveals a modest deviation from December's 32.1°C (89.8°F). Parelhas's average low-temperature in the month of January is recorded at an agreeable 22.1°C (71.8°F).

Heat index

The heat index value for January is computed to be a fiery hot 38°C (100.4°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
