Weather in May
Temperature
A subtle rise in the average high-temperature is observed during May, adjusting from a pleasant 72.7°F (22.6°C) in April to a moderately hot 80.8°F (27.1°C). The nights of May anticipate an average low-temperature of 61°F (16.1°C).Heat index
For May, the heat index is computed to be a hot 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
