Weather in May
Temperature
The shift into May is accompanied by a modest temperature increase, with the average high-temperature edging up from a warm 77.4°F (25.2°C) in April to a still moderately hot 84.2°F (29°C). Heidelberg's nighttime temperature during May is consistently averaged at a refreshing 63.1°F (17.3°C).Heat index
The average heat index in May is evaluated at a tropical 93.2°F (34°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Heat index details are generally centered around shaded locations and a mild breeze. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
