Weather in January

January records an average high-temperature of a still moderately hot 28.3°C (82.9°F), indicating a minor variation from the preceding month. Nightly temperatures drop to an average low of 18.2°C (64.8°F) in January.Heat index
The heat index for January is computed to be a hot 33°C (91.4°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
