The weather in May in Groningen, Suriname, is marked by the year's highest rainfall of 156mm (6.14"). With this, a slight increase in humidity sets in, affecting the overall feel of the days.

Temperature

May's arrival presents an average high temperature of a still moderately hot 29°C (84.2°F), indicating consistency with April's weather. May nights cool to an average low-temperature of 24.7°C (76.5°F), a marginal decrease from its daytime equivalent.

Heat index

The average heat index in May is calculated to be a fiery hot 36°C (96.8°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
