Weather in July
Temperature
In Jamestown, the average temperatures in July are the highest, with a peak at 81.1°F (27.3°C) and a low of 64.8°F (18.2°C).Heat index
The heat index value for July is computed to be a hot 87.8°F (31°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.

Ward off overexposure. Defence against solar harm is crucial. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
