Temperature

With the start of May, the average high-temperature marginally shifts from April's warm 78.4°F (25.8°C) to a still moderately hot 85.3°F (29.6°C). Merlin experiences an average low-temperature reading of 66.4°F (19.1°C) throughout May.

Heat index

May's average heat index is evaluated at a torrid 96.8°F (36°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Heat index details are generally centered around shaded locations and a mild breeze. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
