Weather in August
Temperature
As August takes hold, the average high-temperature is a still warm 27.7°C (81.9°F), nearly mirroring that of the previous month. During August, New York sees a mean low-temperature of 20.4°C (68.7°F).Heat index
The heat index in August is appraised at a tropical 30°C (86°F). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 primarily vital for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Humidity
With an average relative humidity of 70%, August is the least humid month in New York.Rainfall

June through August, with an average maximum UV index of 6, are months with the highest UV index in New York. A UV Index of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the ordinary person.Note: In August, the maximum UV index of 6 transforms into these recommendations:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
