The Beaufort Scale or Beaufort Wind Force Scale is a system for estimating wind strengths without the use of instruments. This is a useful tool in estimating the wind characteristics over a large area, and it may be used to measure and describe the effects of different wind velocities on objects on land.
| BFT NO | CATEGORY | WIND KM/K | LAND CONDITIONS |
| 0 | Calm | <1 km/h | Smoke rises vertically |
| 1 | Light Air | 1-5 km/h | Wind visable in smoke |
| 2 | Light Breeze | 6-11 km/h | Leaves rustle. Wind felt on face |
| 3 | Gentle Breeze | 12-19 km/h | Leaves & twigs in constant motion |
| 4 | Moderate Breeze | 20-28 km/h | Dust & loose paper raise. Small branches begin to move |
| 5 | Fresh Breeze | 29-38 km/h | Branches of moderate size move. Small trees begin to sway |
| 6 | Strong Breeze | 39-49 km/h | Large branches in motion. Whistling heard in overhead wires. Umbrella use becomes difficult. |
| 7 | Near Gale | 50-61 km/h | Whole trees in motion. Inconvenience felt walking against the wind. |
| 8 | Gale | 62-74 km/h | Twigs break on trees |
| 9 | Strong Gale | 75-88 km/h | Some branches break. Some small trees blow over |
| 10 | Storm | 89-102 km/h | Tree uprooted. Considerable structural damage occurs |
| 11 | Violent Storm | 103-117 km/h | Widespread vegetation damage. Roofing surfaces damaged |
| 12 | Hurricane | >118 km/h | Windows may break. Sheds damaged. Debris maybe hurled about. |

For all cantilever umbrellas we advise to position the arm in the direction of the wind (1), tilt knob to be engaged in hole if applicable (2) umbrella canopy to be horizontal. When closing the umbrella, the strap and protection cover need to be correctly used. Failure in doing so can cause damage even in a closed position
For the Paraflex wall mount we advise to position the arm in the direction of the wind (1), completly strech out the arm (2) umbrella canopy to be horizontal (3). When closing the umbrella, the strap and protection cover need to be correctly used. Failure in doing so can cause damage even in a closed position
For Versa UX, we advise to position the umbrella in the direction of the wind (1), put the arm in a 10° angle (2) and put the umbrella on a flat surface. When closing the umbrella, the strap and protection cover need to be correctly used. Failure in doing so can cause damage even in a closed position.
For Monterey, avoid wind from below (1), Put full tension on the canopy (2) Umbrella canopy is to be horizontal (3). Put the umbrella on a flat surface. When closing the umbrella, the strap and protection cover need to be correctly used. Failure in doing so can cause damage even in a closed position.
For our Patio/ market range, we advise to avoid wind from below (1), to put full tension on the canopy (2) and put the umbrella on a flat surface. When closing the umbrella, the strap is to be correctly used. Failure in doing so can cause damage even in a closed position.
The Nova HD, we advise to avoid wind from below (1), and to put full tension on the canopy (2). When closing the umbrella, the strap or halo ring is to be correctly used. Failure in doing so can cause damage even in a closed position.
