Weather in July
Temperature
The Dalles's temperature records reveal July as the warmest month, marked by average highs of 81.7°F (27.6°C) and lows of 54.7°F (12.6°C).Heat index
July's average heat index is calculated to be 82.4°F (28°C). Enduring exposure and continuous activity might cause a feeling of tiredness and induce heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
