What wind region is Gold Coast?
90% of the country is classified in Region A. Region B is coastal New South Wales and as far north as the Gold Coast. Region D is the severe tropical cyclone areas including parts of the Western coastline of Australia.
What does wind rating n2 mean?
Wind Rating n2 The Wind class n2 is the most common wind class used in Australia. It is expected that a wind of more than 90% of the n2 speed may not occur more often than every 20 years and it may be designed for gusts to at least 120% of this speed.
How are cyclones measured in Australia?
When a system becomes a Category 3 tropical cyclone it is reclassified as a Severe tropical cyclone and has wind speeds of 64–85 kn (74–98 mph; 119–157 km/h)….Australian tropical cyclone. intensity scale.
| Category | Sustained winds | Gusts |
|---|---|---|
| Three | 64–85 kt 118–157 km/h | 90–121 kt 167–225 km/h |
What wind region is Kununurra?
Wind Region B
Wind Region B – generally borders Wind Region C. Properties in Wind Region B must therefore be designed to resist weakened tropical cyclones. Towns in Wind Region B include Geraldton, Mullewa, Marble Bar, and Kununurra.
Is 13 km/h wind strong?
10 to 19 km/h Weather wanes will move, leaves will rustle, and you’ll feel a breeze on your face. Situation normal. 20 to 29 km/h Strong enough to straighten flying flags and shake small tree branches. Expect dust and loose paper garbage to fly around in the air.

What is the wind rating in Australia?
Wind Rating Map The above map shows you the approximate wind rating areas in Australia. Starting with Region A, the yellow section, winds are fairly mild and pick up a bit when you move into Region B which is more coastal and you can expect a max of around 147KM/hr at worse. Most of our Australian made sheds are suitable for Regions A and B.
What is an Australian wind map?
Widely employed in Europe and the U.S, wind energy is one of the fastest growing renewable energy resources and is steadily gaining traction in China, India and Australia. An Australian wind map is an atlas of wind strength that is vital when assesing local wind resources.
What is a wind rating and why is it important?
The wind rating is dependent on where your home is located, the topography of the area, the built environment surrounding it and the speed and likelihood of wind gusts expected in bad weather. This rating is the cornerstone of your home’s engineering and ensures it meets the Building Code of Australia.
What are the categories of wind grade?
The categories are important in identifying wind grade as wind is altered by the local terrain. Wind can be influenced and deflected by terrain and neighbourhood structures. Category 2 is open terrain with scattered obstructions, ranging in height between 0.5m – 5m.
