Strong UV — unprotected skin can burn relatively quickly.
UV is high. Unprotected skin can burn in a short time. Plan protection before you head outside.
Recommended precautions
- Use broad-spectrum SPF 30–50; apply generously and reapply after sweating or swimming.
- Limit midday outdoor time (roughly 10 a.m.–4 p.m.) when possible.
- Wear a wide-brim hat, sunglasses, and UPF clothing for outdoor activity.
- Choose shade for breaks — UV still reaches you in light shade, so SPF still matters.
