Weather in September
Temperature
September's average high-temperature stands at a warm 84.7°F (29.3°C), showing little deviation from August's 86.7°F (30.4°C). Melbourne Beach encounters a small divergence from daytime high temperatures, averaging a low-temperature of 77.7°F (25.4°C) during September nights.Heat index
In September, the heat index is calculated to be a very hot 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. 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 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. 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 largely significant for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
