May weather forecast
Chire, French Guiana

The last month of the spring, May, is another warm month in Chire, French Guiana, with an average temperature ranging between min 23.3°C (73.9°F) and max 29.5°C (85.1°F).

Temperature

May brings an average high-temperature of a still moderately hot 29.5°C (85.1°F), showing a slight difference from April's 29.7°C (85.5°F). Chire's average low-temperature in the month of May is recorded at a still warm 23.3°C (73.9°F).

Heat index

The heat index value during May is estimated at a torrid 38°C (100.4°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. 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 primarily vital for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

In May, the average relative humidity is 86%.

Rainfall

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
