Weather in December
Temperature
December tends to be the warmest month, with temperatures averaging a daily high of 32.3°C (90.1°F) and a low of 25.4°C (77.7°F).Heat index
Throughout December, the heat index is calculated to be a scorching 40°C (104°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. 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. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
