The average heat index in January is appraised at a hot 31°C (87.8°F). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes.

Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
