Weather in May
Temperature
With the start of May, the average high-temperature marginally shifts from April's moderately hot 73.9°F (23.3°C) to a still warm 81.9°F (27.7°C). In Ray, the expected average low-temperature for May is a mild 60.4°F (15.8°C).Heat index
The heat index in May is appraised at a tropical 86°F (30°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
