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 beginning of May is characterized by an average high temperature of a still moderately hot 29.8°C (85.6°F), consistent with April's weather. Saul experiences an average low-temperature of 21.9°C (71.4°F) in the month of May.

Heat index

The heat index value during May is evaluated at a scorching 40°C (104°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Note: A typical high UV index of 6 in May suggests the following recommendations:
Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. To cut down UV radiation exposure by about half, sport a wide-brim hat.
