Weather in January

January, like December, in Cortês, Brazil, is another warm summer month, with an average temperature fluctuating between 29.9°C (85.8°F) and 21.3°C (70.3°F).

Temperature

As Cortês transitions into January, the average high-temperature stands at a still moderately hot 29.9°C (85.8°F), offering no variation from the preceding month. Cortês's temperature lowers to a mean of 21.3°C (70.3°F) during the nights in January.

Heat index

In January, the heat index is computed to be a fiery hot 37°C (98.6°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 particularly meaningful for babies and toddlers. 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Humidity

In Cortês, the average relative humidity in January is 78%.

Rainfall

In Cortês, during January, the rain falls for 13.2 days and regularly aggregates up to 22mm (0.87") of precipitation. Throughout the year, there are 200.6 rainfall days, and 433mm (17.05") of precipitation is accumulated.

Sunshine

In January, the average sunshine in Cortês is 7h.

UV index

January through May, September through December, with an average maximum UV index of 6, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for average individuals.
Note: In January, the maximum UV index of 6 translates into these guidelines:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
