January weather forecast
Edwin, French Guiana

January, the same as December, is another warm winter month in Edwin, French Guiana, with an average temperature ranging between max 29.8°C (85.6°F) and min 20.7°C (69.3°F).

Temperature

Edwin signifies an average high-temperature of a warm 29.8°C (85.6°F) in January, closely mirroring the 30.9°C (87.6°F) of December. An average low-temperature of 20.7°C (69.3°F) is noted during the month of January.

Heat index

The heat index value during January is computed to be a sweltering 39°C (102.2°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Guard against overexposure. Protection from sun-induced harm 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. Stay sun-safe with clothing that is both closely woven and worn loosely.
