Weather in August
Temperature
In August, the average high-temperature registers at a still warm 81.1°F (27.3°C), nearly identical to July's 82.6°F (28.1°C). Despite the drastic temperature difference, Humboldt records an average nighttime low of 59.5°F (15.3°C) throughout August.Heat index
During August, the heat index is estimated at a hot 86°F (30°C). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
