Do I need sunscreen in Mexico City today?
Use the live reading above: the protection threshold is UV 3. If any part of your time outdoors falls in the hours marked moderate or higher, wear SPF 30+ broad-spectrum sunscreen and reapply every two hours. Water, sand, and snow reflect UV and can push your effective exposure well above the forecast number — as does altitude, at roughly +10% per 1,000 m.
