Weather in May
Temperature
May comes with a subtle rise, with the average high-temperature adjusting from 73.8°F (23.2°C) in April to a still warm 81.5°F (27.5°C). During the nights in May, McNab experiences a consistent average temperature of 61.3°F (16.3°C).Heat index
For May, the heat index is evaluated at a tropical 87.8°F (31°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
