WIND STRENGTH can be indicated in several different ways - here we have made a comparison between the most common.
Beaufort | m/s | knots | km/h | Name | Wave | At open sea | On land |
---|---|---|---|---|---|---|---|
0 | 0 - 0,2 | 0-1 | 0 - 0,72 | Calm | 0 m | Water surface like a mirror. The strokes will often become weaker. |
No effect - Possible spots for tents are numerous. |
1 | 0,3 - 1,5 | 2-3 | 1,08 - 5,4 | Light Air | 0,1 m | Ripple - A long tour migth become tiresome as one cannot see the movement. | Noticeable at the skin -A tent will stand up where it was put. |
2 | 1,6 - 3,3 | 4-6 | 5,76 - 11,88 | Light Breeze | 0,2 m | Minor waves that don’t break - Nice to paddle invites to good speed even in head wind. | Small leaves and branches moves and a pennant will lift - The canvas moves |
3 | 3,4 - 5,4 | 7-10 | 12,24 - 19,44 | Gentle Breeze | 0,6 m | Wave crests starts breaking - Still posible to paddle without thinking about wind direction. | Leaves and branches in constant move and pennant will stretch out -No problems for a tent. |
4 | 5,5 - 7,9 | 11-16 | 19,8 - 28,44 | Moderate Breeze | 1,0 m | Longer waves with more white crests and breaks with a short noise -It's tiresome to paddle in head wind. | A flag will stretch out and thinner branch will move - Nice if the tent is in a sheltered area. |
5 | 8 - 10,7 | 17-20 | 28,8 - 38,52 | Fresh Breeze | 2,0 m | More distinct waves with white spray breaking with constant noise - Tiresome paddling even on sheltered water. | Larger branches swing and electric lines blow - Time to check the lines holding the tent. |
6 | 10,8 - 13,8 | 21-27 | 38,88 - 49,68 | Strong Breeze | 3,0 m | Larger waves with large fields of spray and a roaring sound - Each paddle stroke doesnt bring you far and smaller boats search for land. | Larger branches swing and electric lines blow - Time to find some extra support lines for the tent if it is not sheltered |
7 | 13,9 - 17,1 | 28-33 | 50,04 - 61,56 | Near Gale | 4,0 m | The surfs will be heard far away and the spray foam forms long strings - The boating people have searched for sheltered marinas. | Entire trees are moving and it’s hard to walk in the wind - Hope the tent lines will hold. |
8 | 17,2-20,7 | 34-40 | 61,92 - 74,52 | Gale | 5,5 m | The sea is roaring and the foam is seen in long and close strings - A faschination view if ashore | Branches are broken off from the trees - Hope no branch will drop on the tent. |
9 | 20,8 - 24,4 | 41-47 | 74,88 - 87,84 | Strong Gale |
7,0 m | High waves with foam string whipped up in the air and decrease the sight - The waterlevel will rise drastically at wind towards land. | Minor damages at house and roof tiles blow down - it's a never ending duty to retigthen the tent lines. |
10 | 24,5 - 28,4 | 48-55 | 88,2 - 102,24 | Storm | 9,0 m | The sea looks almost white and the thunder from breaking waves comes irregularly - This is seriously even to large ships. | Rare in the inland and trees are falling with its roots - After a storm comes calm wind so rest if possible. To gain strength to move on. |
