Weather in January
Temperature
Guarantã experiences an average high-temperature of a still warm 29.2°C (84.6°F) in January, subtly different from December's 29.8°C (85.6°F). During January, the nighttime temperature averages of 20.8°C (69.4°F).Heat index
January's mean heat index is estimated at a very hot 36°C (96.8°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. 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. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
