Weather in June

June, the first month of the summer in Winchester, is a hot month, with an average temperature varying between 69.4°F (20.8°C) and 86.9°F (30.5°C).

Temperature

The arrival of June brings a change in Winchester's weather, with average high-temperatures moving from May's warm 76.5°F (24.7°C) to a tropical 86.9°F (30.5°C). Throughout June, an average low-temperature of 69.4°F (20.8°C) is expected.

Heat index

June's average heat index is computed to be a sweltering 100.4°F (38°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital 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.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

As much as possible, limit direct sun exposure during this period. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
