Weather in December
Temperature
December's climate shows a minor adjustment in average high-temperatures to a still warm 29.3°C (84.7°F) from November's 29.5°C (85.1°F). During December, an average low-temperature of 24.2°C (75.6°F) is observed.Heat index
The heat index value during December is computed to be a fiery hot 36°C (96.8°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm 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. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
