Weather in May
Temperature
As May arrives, Petrolia's weather shows a minor increase in high-temperatures, edging from April's warm 74.5°F (23.6°C) to a still moderately hot 81.9°F (27.7°C). Petrolia's temperature in May lowers to a consistent average of 62.2°F (16.8°C) during the nights.Heat index
May's heat index is appraised at a tropical 86°F (30°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Note that heat index values are valued for light wind and location in the shade. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
