Weather in January
Temperature
January, known for its average high temperature of 28.8°C (83.8°F) and an average low temperature of 16.3°C (61.3°F), is the warmest month.Heat index
The heat index value during January is estimated at 29°C (84.2°F). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.

A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for average individuals.Note: In January, the maximum UV index of 6 transforms into these recommendations:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
