Weather in May
Temperature
As May sets, the average high-temperature shows a slight increase, moving up from 77.7°F (25.4°C) in April to a still warm 83.7°F (28.7°C). During the month of May, Grandbois's nighttime temperature lowers to an average of 68.9°F (20.5°C).Heat index
The heat index value for May is evaluated at a tropical 91.4°F (33°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
