Weather in June

June, the first month of the summer in Heidelberg, is still a warm month, with an average temperature fluctuating between 83.7°F (28.7°C) and 61.3°F (16.3°C).

Temperature

A gentle upsurge in temperatures occurs as May gives way to June, with average highs shifting from a warm 75.9°F (24.4°C) to a still moderately hot 83.7°F (28.7°C). Throughout June nights, Heidelberg reports a steady thermal contrast from the day, with an average low-temperature of 61.3°F (16.3°C).

Heat index

During June, the heat index is estimated at a tropical 91.4°F (33°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 relevant to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
