December weather forecast
Pomona, Guyana

December, the first month of the winter in Pomona, is still a warm month, with an average temperature varying between 22.4°C (72.3°F) and 29.9°C (85.8°F).

Temperature

The average high-temperature in December, at a moderately hot 29.9°C (85.8°F), reveals a modest deviation from November's 31.5°C (88.7°F). December generally records an average low-temperature of 22.4°C (72.3°F).

Heat index

During December, the heat index is estimated at a sweltering 39°C (102.2°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
In reference to the heat index, it's for places in shade and with a slight wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

The average relative humidity in December is 84%.

Note: The UV index of 6 during December leads to these advisories:
Resist overexposure. Safeguarding from solar damage is indispensable. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
