Weather in May
Temperature
Grandfield observes a slight uplift in the average high-temperature with the onset of May, adjusting from April's moderately hot 74.8°F (23.8°C) to a still warm 82.8°F (28.2°C). Throughout May, Grandfield records an average temperature of 62.6°F (17°C) at night.Heat index
May's heat index is estimated at a hot 87.8°F (31°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
