Weather in May

In the intermediate narrative of Vicksburg's annual climatic journey, May introduces significant warmth, serving as a precursor to the summer months. The daily temperatures routinely cross into the 80s°F, signalling the city's transition into the hot season. Longer sunshine hours permit extensive outdoor activities, while the humidity remains fairly steady. The overall character of May weather stands out as the spring elements retreat, ultimately paving the path for summer's arrival. Rainfall provides a cooling relief to the escalating temperatures of this period.

Temperature

May's arrival signals a modest temperature shift, moving from 75.2°F (24°C) in April to a still warm 83.1°F (28.4°C). During the month of May, the temperature generally drops to a low average of 63.5°F (17.5°C).

Heat index

The heat index for May is estimated at a hot 89.6°F (32°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.
Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
