Weather in May
Temperature
With the start of May, the average high-temperature marginally shifts from April's moderately hot 74.8°F (23.8°C) to a still warm 82.9°F (28.3°C). McMullen experiences an average low-temperature reading of 62.2°F (16.8°C) throughout May.Heat index
For most parts of May, the heat index is appraised at a hot 89.6°F (32°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.One should consider that heat index numbers are for shaded settings and light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
