Weather in May
Temperature
With the onset of May, Grand Coteau observes a minor temperature ascent, with the average high-temperature adjusting from April's 77.5°F (25.3°C) to a still warm 84.6°F (29.2°C). Grand Coteau reports an average nighttime low-temperature of 66.4°F (19.1°C) in May.Heat index
The heat index in May is computed to be a very hot 95°F (35°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.The standards for the heat index are set for locations in shade and under light breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. 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 largely significant for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
