Weather in August

August, the last month of the summer in Welcome, is also a hot month, with an average temperature fluctuating between 88.3°F (31.3°C) and 67.6°F (19.8°C).

Temperature

August commences with an average high-temperature of a still hot 88.3°F (31.3°C), showing little deviation from July's 90.3°F (32.4°C). During August, Welcome records an average temperature of 67.6°F (19.8°C) at night.

Heat index

For August, the heat index is calculated to be a very hot 102.2°F (39°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Prevent overexposure. Protection from the sun's harmful effects is needed. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
