Weather in August
Temperature
Heyburn's entry into August measures an average high-temperature of a still hot 90.9°F (32.7°C), closely parallel to the preceding month. Heyburn, during the month of August, experiences an average low-temperature of 70.3°F (21.3°C).Heat index
For most parts of August, the heat index is computed to be a scorching 105.8°F (41°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

A UV Index reading of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for ordinary individuals.Note: The maximum UV index of 7 during August translates into these guidelines:
Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
