Understanding the UV Index in Richfield, United States is crucial for maintaining your skin health and preventing sunburn. This index provides valuable insight into the levels of ultraviolet radiation you may be exposed to throughout the day, especially as the sun reaches its peak intensity during midday hours. With Richfield’s Cfa climate, characterized by warm summers and variable weather, residents must remain vigilant about UV exposure, particularly when the index climbs to levels of 8 to 10 between 11 AM and 2 PM. Staying informed not only helps protect your skin but also promotes overall well-being during outdoor activities.
The UV Index starts off low at 1 during the early hours, peaking at 9 by noon and reaching its maximum of 10 between 1 PM and 2 PM. This signifies a critical period when sun protection is vital, as the intensity of UV rays can cause skin damage. As the afternoon progresses, the index gradually decreases, falling to 6 by 4 PM, then dropping to 2 by 6 PM and settling back to 1 as evening falls. If you’re planning outdoor activities, make sure to stay safe and shield yourself when the sun is at its strongest!

Throughout the year, the UV Index displays significant seasonal fluctuations that warrant attention from both visitors and residents. From January (UV Index 4, moderate exposure) to February (UV Index 6, high exposure), there is a notable increase in ultraviolet radiation, leading to higher sunburn risk. The months of March through June represent high-risk periods, with UV Index values peaking at 11 in June (extreme exposure) and maintaining levels above 8 until September. During this summer surge, burn times can dwindle to as little as 10 minutes in June. September to October shows a slight decrease, though values remain high (UV Index 9-8). Following this, November and December return to more moderate levels (UV Index 5 and 3), allowing for longer exposure times without an immediate burn risk. It is advisable for everyone to stay vigilant during the high-risk months, particularly from March to September, and to employ protective measures such as wearing sunscreen and protective clothing, especially during peak hours.
