Thank you - this is an interesting site with great resolution in time and space for mean wind speeds.  However - and perhaps I missed it - I don't see wind extremes on here, which is the core of my question. Is there a way to get that data (i.e. maximum gust speed in a given time period) from this site?

When you click a certain location on the map, it brings up some key information. Which includes a distribution of wind speeds. (percentile buckets). You can export that information out as well.

I'm looking for a world map of wind gust climatology data, with the specific purpose of being used for coarse comparison of building design loads, with a consistent metric regardless of location.

Ideally it would be very similar to what's used in building codes, such as "basic wind speed" in ASCE 7 for the US & International Building Code, and comparable codes for other regions: a contour map or heat map of the max value with a 50-year return period (or similar statistic, with various levels for different risk profiles). See the US map [here](https://codes.iccsafe.org/content/IBC2018/chapter-16-structural-design#IBC2018_Ch16_Sec1609.3) and one for India (below, [source](https://skyciv.com/docs/tech-notes/loading/is-875-3-wind-load-calculation-example/)).

I have found world maps of other climatology and extreme value data, but none for high-percentile gusts. Most of the global wind data maps are oriented towards power generation. I'm not sure what resolution I need, probably 1- or 2- degree would be fine, but it would have to come from a higher-resolution source to capture local maxima.

Have you checked out [Global Wind Atlas](https://globalwindatlas.info/). It uses ERA5 reanalysis data then plugs it into meso and microscale models to get it down to a 250x250m grid.
