August weather forecast
Merizo, GU

As one steps into August, it becomes clear that it is one of the highest rainfall months of the year. The month mirrors July's robust climate pattern with a consistently high temperature and relative humidity level. August witnesses a slight decline in sea temperature, from 85.4°F (29.7°C) to 85°F (29.4°C), consistent with the fluctuating tropical weather. Coupled with a decreased wind speed, it further showcases the unpredictable weather nature inherent to Merizo. Regardless of such fluctuations, the overall sea and weather conditions remain favorable for water activities.

Temperature

July and August bring Merizo's highest average temperatures, reaching a high of 84.7°F (29.3°C).

Heat index

The heat index for August is evaluated at a fiery hot 95°F (35°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
