Weather in May
Temperature
May introduces a minor temperature shift, with average high-temperatures adjusting from April's moderately hot 74.1°F (23.4°C) to a still warm 81.5°F (27.5°C). In May, the temperature drops to an average of 60.8°F (16°C) at night.Heat index
The heat index for May is evaluated at a tropical 86°F (30°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
