Weather in May
Temperature
Guy's weather in May shows a minor rise in the average high-temperature, moving slightly up from April's moderately hot 78.3°F (25.7°C) to a still warm 85.1°F (29.5°C). May brings with it a nighttime average temperature of 68.7°F (20.4°C).Heat index
For most parts of May, the heat index is appraised at a very hot 96.8°F (36°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. To cut down UV radiation exposure by about half, sport a wide-brim hat.
