Enhanced protection from UV radiation from the Sun is required. A UV index reading of 11 or more means extreme risk of harm from unprotected sun exposure. Take all precautions because unprotected skin and eyes can burn in minutes. Try to avoid sun exposure between 10 a.m. and 4 p.m. If outdoors, seek shade and wear sun protective clothing, a wide-brimmed hat, and UV-blocking sunglasses. Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating. Bright surfaces, such as sand, water, and snow, will increase UV exposure.
On land:
The wind picks up dust and small pieces of paper; small branches are moved.
At Sea:
The sea is moderately rough. Waves appear in the form of elongated ridges, some of which are overturned; fairly frequent white horses.
On land:
The thin branches and leaves on the trees fluctuate continuously; wind extends light flag.
At Sea:
Light and short waves are clearly visible at sea. Foam of glassy appearance. Perhaps scattered white horses.
On land:
There is a light continuous stream of wind that is felt by the face; leaves rustle; ordinary vanes moved by wind.
At Sea:
Weak and short waves in the sea, still short, but more pronounced. Crests have a glassy appearance and do not break.
On land:
Thin branches and tree trunks sway, and the wind is felt by the hand.
At Sea:
The sea is rough, not very large waves are well developed in length; many white horses are formed.
Protection from UV radiation from the Sun is not necessary. A UV index reading of 0 to 2 means low danger from the sun's UV rays for the average person. Wear sunglasses on bright days. If you burn easily, cover up and use broad spectrum SPF 30+ sunscreen. Bright surfaces, such as sand, water, and snow, will increase UV exposure.
On land:
Large branches of trees sway, and thin ones bend; whistling heard in telegraph wires; umbrellas used with difficulty.
At Sea:
Large waves form on the sea; the white foam crests are more extensive everywhere.
