Weather in September
Temperature
In Rio Rico, entering September brings a subtle temperature decrement, reducing from August's fiery hot 36.6°C (97.9°F) to a hot 33.6°C (92.5°F). Rio Rico experiences a mean low-temperature of 25.2°C (77.4°F) during September.Heat index
The average heat index in September is computed to be a blisteringly hot 44°C (111.2°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Understanding the heat index involves considering values for shaded locales with light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Sunshine
In Rio Rico, the average sunshine in September is 8.3h.UV index
The average daily maximum UV index in September is 7. A UV Index value of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for the ordinary person.Note: The maximum UV index of 7 during September translates into these guidelines:
Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
