Weather in September
Temperature
September's arrival brings an average high-temperature of a warm 84.7°F (29.3°C), demonstrating subtle variation from the preceding month. Jupiter records a slight downturn in temperature to an average of 79.3°F (26.3°C) during September nights.Heat index
The heat index value during September is estimated at a sweltering 95°F (35°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
Humidity
The average relative humidity in September is 76%.Rainfall
In Jupiter, Florida, in September, during 25.4 rainfall days, 5.75" (146mm) of precipitation is typically accumulated. Throughout the year, there are 230.9 rainfall days, and 46.73" (1187mm) of precipitation is accumulated.Ocean temperature
In Jupiter, the average seawater temperature in September is 84.7°F (29.3°C).Note: Water temperature between 77°F (25°C) and 84.2°F (29°C) provides warmth and pleasure, making water activities enjoyable for lengthened periods without feeling uncomfortable.
Daylight
The average length of the day in September is 12h and 19min.On the first day of September, sunrise is at 7:00 am and sunset at 7:40 pm. On the last day of the month, sunrise is at 7:12 am and sunset at 7:07 pm EDT.
Sunshine
The average sunshine in September is 8.9h.UV index
May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for ordinary individuals.Note: A daily high UV index of 7 in September leads to these guidelines:
Resist overexposure. Safeguarding from solar damage is indispensable. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. Alert! UV radiation becomes sharper due to reflections from sand and water.
