Weather in August
Temperature
August brings a marginal elevation to a still tropical 87.8°F (31°C) from July's 89.2°F (31.8°C) in Butterfield's average high-temperatures. An average low-temperature of 66.6°F (19.2°C) is recorded in the month of August.Heat index
During August, the heat index is appraised at a very hot 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for average individuals.Note: In August, the average maximum UV index of 6 translates into the following recommendations:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
