Weather in May
Temperature
May's arrival is noted with a slight increase in the average high-temperature, moving from a warm 77.9°F (25.5°C) in April to a still moderately hot 85.6°F (29.8°C). O'Brien marks a considerable descent from the daytime apex, as the average temperature dips to a comfortable 63.7°F (17.6°C) at night throughout May.Heat index
The average heat index in May is evaluated at a hot 89.6°F (32°C). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical 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.
