Weather in May
Temperature
As Harrisburg transitions into May, the average high-temperature is observed to slightly rise from a pleasant 73°F (22.8°C) in April to a warm 81°F (27.2°C). An average low-temperature of 60.1°F (15.6°C) is common during the nights of May.Heat index
In May, the average heat index is appraised at a hot 86°F (30°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for 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.
