Weather in May

With the onset of May, Rockdale's average high-temperature experiences a slight rise, moving from April's 76.5°F (24.7°C) to a still moderately hot 83.1°F (28.4°C). Rockdale experiences an average nighttime temperature of 65.5°F (18.6°C) in the month of May.Heat index
The heat index value during May is calculated to be a hot 91.4°F (33°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Consider that heat index readings are for situations in the shade and light wind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
