Weather in January
Temperature
January brings an average high-temperature of a moderately hot 29.9°C (85.8°F), showing a slight difference from December's 30.9°C (87.6°F). The average temperature during January nights is registered at 23.2°C (73.8°F).Heat index
Throughout January, the heat index is estimated at a very hot 38°C (100.4°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. 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 sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Sunshine

January and March, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for the average person.Note: The maximum UV index, 6 during January, leads to the following recommendations:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
