Weather in August
Temperature
August, recognised by an average high temperature of 29.1°C (84.4°F) and a low of 13.1°C (55.6°F), is Montalegre's warmest month.Heat index
August's heat index is estimated at a hot 31°C (87.8°F). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
