Weather in May
Temperature
As April transitions into May, a subtle temperature shift is observed, with average highs adjusting from a moderately hot 77.9°F (25.5°C) to a still warm 83.8°F (28.8°C). In Gray, May nights witness a steady temperature drop to a pleasant 68°F (20°C).Heat index
In May, the heat index is evaluated at a hot 93.2°F (34°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.The metrics for the heat index are tailored for both shady environments and light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
