Weather in May
Temperature
A slight uplift of average high-temperatures is noted in May, with temperatures adjusting from a moderately hot 77.9°F (25.5°C) in April to a still warm 84.7°F (29.3°C). During the nights in May, Roseland experiences a consistent average temperature of 64.9°F (18.3°C).Heat index
During May, the heat index is appraised at a torrid 95°F (35°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
