Weather in May
Temperature
With the start of May, the average high-temperature marginally shifts from April's 74.8°F (23.8°C) to a still warm 82.4°F (28°C). During May, Isabella witnesses a consistent average low-temperature of 61.5°F (16.4°C).Heat index
The heat index value for May is estimated at a hot 87.8°F (31°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
