Weather in May
Temperature
The beginning of May marks a minor shift in the average high-temperature, moving from April's 73.6°F (23.1°C) to a still warm 81.1°F (27.3°C). Dyson's temperature tends to fall to an average low of 61°F (16.1°C) during the nights of May.Heat index
For May, the heat index is evaluated at a hot 86°F (30°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.

Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
