May weather forecast
Saul, French Guiana

Conditions continue to remain similar in May, the highest rainfall month of the year with a whopping 192mm (7.56") precipitation. Travelers looking forward to sunny landscapes must anticipate an overall reduction in visibility due to the high cloud cover. The significantly raised rain levels, combined with enduring high humidity, result in a moister environment. Yet, these moist circumstances do not seem to significantly affect daily temperatures. Transitioning into June, the weather begins to hint at some noteworthy changes.

Temperature

The advent of May in Saul, French Guiana, brings an average high-temperature of a still moderately hot 29.8°C (85.6°F), almost the same as the preceding month. In the month of May, the average temperature in Saul, French Guiana, dips to a pleasant 21.9°C (71.4°F) during the night.

Heat index

For most parts of May, the heat index is computed to be a scorching 40°C (104°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. 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 especially crucial for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
