Weather in July
Temperature
Lewes registers the highest average temperatures during the month of July, with peaks of 80.6°F (27°C) and lows of 73°F (22.8°C).Heat index
July's average heat index is calculated to be a tropical 86°F (30°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.

Stay clear of intense sun exposure. Solar protection is of utmost significance. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. To cut down UV radiation exposure by about half, sport a wide-brim hat. Caution! The mirror effect of sand and water ups the UV radiation strength.
