Sun safety for Seoul
Seoul runs in the very high UV band through June – August. Fair skin can burn in 15–25 minutes at noon. Daily SPF 50, hat, and shade between 11am and 3pm are basic protection. SPF 30 is enough only outside peak hours.
Reapply every 2 hours — every 90 minutes if outdoors continuously. Cloud cover reduces UV less than people assume; up to 80% gets through. Cumulative exposure across a summer adds up regardless of any single day's reading.
Whatever Seoul's climatology says, the live reading above is what counts on the day you check. UV varies hour by hour; the widget shows current and forecast values so you can plan around peak hours.
Why daily UV awareness matters in Seoul
UV exposure is the leading preventable cause of skin cancer. Each blistering sunburn before age 20 doubles melanoma risk in adulthood. Cumulative UV from daily, unprotected exposure causes basal cell carcinoma, squamous cell carcinoma, premature aging, and pigmentation disorders.
For residents of Seoul, the practical impact of knowing today's UV is choosing the right SPF strength, the right outdoor schedule, and the right protective clothing for the next few hours — not abstract long-term advice. The widget above turns this into a 5-second daily check.
