January signals the onset of the rainy season in Saul, French Guiana. Despite this downpour, temperatures remain steadily high hovering near 30°C (86°F). The weather pattern this month is generally characterized by significant rainfall and high humidity, with rainfall reaching up to 86mm (3.39") and a relative humidity of 87%. The daylight lasts for a little less than half of the day, casting the city under the soft shadows of clouds for a sizeable portion of the day. These climatic conditions set the tone for the next few months, each carrying their unique variables.

Temperature

With January's arrival, Saul's weather records an average high-temperature of a warm 29.7°C (85.5°F), marking little difference from December's 30.8°C (87.4°F). Nightly temperatures in Saul drop to an average low of 20.8°C (69.4°F) in January.

Heat index

The heat index value during January is evaluated at a torrid 39°C (102.2°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
