Cascade's August weather, with an average high temperature of 29.7°C (85.5°F) and an average low temperature of 26.8°C (80.2°F), tends to be the warmest of the year.

Heat index

In August, the heat index is estimated at a fiery hot 36°C (96.8°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

The average relative humidity in August is 77%.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
