Temperature

The onset of December manifests an average high-temperature of a still tropical 32.7°C (90.9°F), demonstrating a minor variation from the preceding month. December in Colva generally records an average low-temperature of 22.4°C (72.3°F).

Heat index

December's mean heat index is computed to be a very hot 38°C (100.4°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Watch out! Sand and water enhance the UV exposure you receive.
