Temperature

August stands out as Royal Palm Beach's warmest month, with an average high-temperature of 88.2°F (31.2°C) and a low-temperature of 79.7°F (26.5°C).

Heat index

Throughout August, the heat index is calculated to be an extremely hot 104°F (40°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
