Weather in May
Temperature

The heat index in May is calculated to be a hot 89.6°F (32°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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 particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
