Weather in May
Temperature
The transition into May notes an average high-temperature of a still moderately hot 29.3°C (84.7°F), revealing a mild distinction from the 28.8°C (83.8°F) in April. An average temperature of 24.4°C (75.9°F) is logged during the nights of May, a small step down from daytime highs.Heat index
May's average heat index is computed to be a torrid 37°C (98.6°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
