According to the Google search result for this query:
"The highest wind speeds recorded in Antarctica were at Dumont d'Urville station in July 1972: 327km/h (199 mph),"
The average wind speed in Antarctica is 67 kilometres per hour; the maximum wind speed is 320 kilometres per hour (198.8 miles per hour).
Based on this, Antarctica would average around 40km/h.
Winds can speed up to 200 km/h which will obviously blow you over. But Antarctica doesn't really have much weather. So winds, blizzards and storms don't really happen often.
Wind speed in Antarctica vary as they do anywhere else on Earth. You get windy days and still days.
