Caledonia, Guyana

The last month of the spring, May, is another hot month in Caledonia, Guyana, with an average temperature varying between 23.1°C (73.6°F) and 30.5°C (86.9°F).

Temperature

Caledonia observes a minor difference in average high-temperatures between April's 30.8°C (87.4°F) and May's 30.5°C (86.9°F). Throughout the month of May, Caledonia observes an average nighttime temperature of 23.1°C (73.6°F).

Heat index

During May, the heat index is computed to be an extremely hot 40°C (104°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In May, the average relative humidity in Caledonia is 82%.

Note: In May, the UV index of 6 transforms into the following advice:
Deflect overexposure. Sun protection is a necessity. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
