Weather in September
Temperature
Hanson observes an average high-temperature of a still tropical 88°F (31.1°C) in September, barely different from 91°F (32.8°C) in August. Hanson experiences a nighttime temperature average of 70°F (21.1°C) during September.Heat index
Throughout September, the heat index is calculated to be a scorching 104°F (40°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. 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. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
Humidity
The average relative humidity in September is 77%.Rainfall
In September, the rain falls for 19.2 days. Throughout September, 3.35" (85mm) of precipitation is accumulated. In Hanson, during the entire year, the rain falls for 181.5 days and collects up to 34.76" (883mm) of precipitation.Snowfall

Sunshine
The average sunshine in September is 8.4h.UV index
In Hanson, the average daily maximum UV index in September is 6. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for the average person.Note: The maximum UV index of 6 during September translates into these guidelines:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
