August, the last month of the summer in Shannon, is another tropical month, with temperature in the range of an average high of 90.7°F (32.6°C) and an average low of 70.9°F (21.6°C).

Temperature

Shannon's weather in August indicates an average high-temperature of a still tropical 90.7°F (32.6°C), nearly consistent with the 90.9°F (32.7°C) of July. During August, Shannon's temperature averages to a pleasant 70.9°F (21.6°C) at night.

Heat index

In August, the average heat index is computed to be a blisteringly hot 109.4°F (43°C). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Realize that the values for the heat index are set for shaded places and light winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

The average relative humidity in August is 73%.

Rainfall

In Shannon, during August, the rain falls for 16.3 days and regularly aggregates up to 2.36" (60mm) of precipitation. In Shannon, during the entire year, the rain falls for 155.2 days and collects up to 33.27" (845mm) of precipitation.

UV index

The average daily maximum UV index in August is 6. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for average individuals.
Note: In August, an average UV index of 6 transforms into the following instructions:
Inhibit overexposure. Warding off sun damage is of utmost importance. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
