Weather in January
Temperature
The transition into January reveals an average high-temperature of a warm 29.4°C (84.9°F), mirroring a close resemblance to December. An average low-temperature of 22.4°C (72.3°F) is recorded in the month of January in Maman Valentin, French Guiana.Heat index
During January, the heat index is computed to be a torrid 36°C (96.8°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
