Weather in August
Temperature
During August, Gwynedd Valley observes a subtle ascent to a still warm 82.8°F (28.2°C) from July's 85.3°F (29.6°C) in the average high-temperature. In the month of August, the temperature generally rests at an average low of 65.3°F (18.5°C).Heat index
The heat index value during August is computed to be a hot 87.8°F (31°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Heat index determinations are made taking into account the shade and light air movements. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
