The heat index value during May is appraised at a hot 86°F (30°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.In the scope of the heat index, its values resonate with shade and light wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics.
