Weather in May

May, the last month of the spring in Brignac, is also a moderately hot month, with an average temperature varying between 66°F (18.9°C) and 84.7°F (29.3°C).

Temperature

With the beginning of May, Brignac's average high-temperature sees a minor increase, transitioning from a moderately hot 78.4°F (25.8°C) in April to a still warm 84.7°F (29.3°C). Nighttime temperature lowers to an average of 66°F (18.9°C) in May.

Heat index

May's average heat index is computed to be a torrid 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
