The Wind Score for Canada, powered by AISIX uses a downscaled, bias corrected, multi-model ensemble for 1-in-100 year wind gust speeds by mid-century for a middle-of-the-road climate change scenario (SSP2). The dataset simulates future wind patterns at a 25 km scale.

We determine the extreme wind gust speed distribution across Canada from historical data and projections of 21st century extreme wind magnitudes and assign risk scores based on a modified version of the Beaufort wind scale.

The data simulates the extremes in regional wind patterns, but further extremes should be expected at finer scales. This is because the operating resolution of climate model products simplifies terrain and atmospheric aspects of winds into larger grid cells, and our statistical models of extreme wind events include data spanning just over a century that might not have captured extraordinarily unlikely ‘black swan’ events. The SSP2 climate change scenario assumes that socio-economic trends do not shift significantly from current global patterns. This climate change scenario represents a middle ground between a low-warming future characterized by proactive societal mitigation of a changing climate, and a high-warming future that does not mitigate climate change in pursuit of socio-economic development.



To enhance the accuracy and transparency of the probabilities, Aisix has implemented a classification system consisting of five distinct levels: 1 to 5, based on the daily wind gust speed in km/h: 

Please Note:
AISIX scores are driven by probabilities, which means they are not certain. The data simulates the extremes in regional wind patterns, but further extremes should be expected at finer scales. It’s important to be careful when understanding these scores. Remember that even if something is likely, it is not guaranteed. The opposite is also true.

  1. What is a wind risk score?
    Aisix’s wind score represents how the daily wind gust speed will be for a given location compared the average for Canada. The higher the wind score, the higher the maximum wind by mid-century.
  2. How often is the wind risk score updated?
    Wind risk scores are typically updated annually to reflect new data and environmental changes. 
  3. Is my property’s wind risk score based on current weather conditions?
    While the base score incorporates historical and geographical data, it may not reflect real time conditions.
  4. Can the wind risk score change over time?
    Yes, the score can change due to factors like climatic changes and improvements in risk assessment technologies. Regular updates incorporate these changes to keep the score as accurate as possible.
  5. Who can I contact for more detailed information about my property’s wind risk?
    For more detailed information, contact
  6. What should I do if I disagree with my wind risk score?
    If you disagree with your score, you can request a review or reassessment.
