Weather in September
Temperature
The arrival of September sees a recorded average high-temperature of a still tropical 88°F (31.1°C), showing little divergence from the previous month's conditions. During September, Boyce experiences an average low-temperature of 68°F (20°C) at night.Heat index
The heat index value for September is estimated at a blistering 104°F (40°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Opt for tightly woven and loose clothing to enhance protection from the Sun. Remember this! The UV radiation of the Sun can be nearly doubled by the reflective properties of snow.
