Weather in August
Temperature
Transitioning into August, Alfalfa records an average high-temperature of a still warm 80.6°F (27°C), almost identical to July's 81.1°F (27.3°C). In Alfalfa, a significant divergence from daytime highs is recorded, with average lows of 54.3°F (12.4°C) during August nights.Heat index
August's heat index is estimated at 80.6°F (27°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
