Weather in September
Temperature
Raymond experiences a minor change to a still tropical 87.4°F (30.8°C) in average high-temperature during September, closely reflecting August. During the September nights, an average temperature of 68°F (20°C) is observed.Heat index
September's average heat index is computed to be a sweltering 100.4°F (38°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 are highly critical to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

In Raymond, during September, the rain falls for 13.5 days and regularly aggregates up to 2.2" (56mm) of precipitation. Throughout the year, there are 161.5 rainfall days, and 31.65" (804mm) of precipitation is accumulated.Snowfall

Sunshine
In September, the average sunshine is 9.6h.UV index
In Raymond, the average daily maximum UV index in September is 6. A UV Index estimate of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for the ordinary person.Note: In September, an average UV index of 6 transforms into the following instructions:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
