Weather in June
Temperature
With the transition into June, Lancaster experiences a subtle uplift in average high-temperatures, adjusting from a moderately hot 74.3°F (23.5°C) in May to a still warm 82.9°F (28.3°C). An average nighttime temperature of 65.8°F (18.8°C) is noted during the month of June.Heat index
The heat index value during June is appraised at a tropical 91.4°F (33°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
