What is high winds for football?
Studies show that winds of over 18 mph alter the course of direction of the football, whether it's thrown or kicked. And in college football, teams are slightly less successful when throwing in strong winds making interception rates are higher. On average, shorter passes are thrown and fewer field goals are attempted.
Microbursts of between 10 and 15 mph could send a football flying a dozen yards or more to the right or left of its intended target.

8-12 Mph 12-19 kph 7-10 knots Gentle Breeze Leaves and small twigs move, light weight flags extend. Large wavelets, crests start to break, some whitecaps. 13-18 Mph 20-28 kph 11-16 knots Moderate Breeze Small branches move, raises dust, leaves and paper.

- at 25 to 31 mph, large branches will be in motion, whistling will be heard in overhead wires, and umbrella use becomes difficult if not impossible. - at 32 to 38 mph, whole trees will be in motion. You'll experience some difficulty when walking into the wind.
Strong winds can cause the quarterback (QB) to not be able to throw the ball where they want to or make a field goal attempt to miss badly. Studies have shown that as winds become stronger than 18 mph, the flight of a thrown or kicked ball is altered.
Football, at both the club and international levels, has often been forced to succumb to the elements—to heat, wind, rain and, at least on one occasion, to volcanoes. Following are 20 instances of weather wreaking havoc on football matches.
Is defined as sustained winds averaged over a 10 minute period and measured 20 feet above the average height of nearby vegetation. This is the standard reported by the Remote Automated Weather Stations(RAWS) owned by land management agencies and used in the National Fire Danger Rating System (NFDRS).
Hurricane winds - 130 to 160 mph gusts 170+ mph: Devastating damage is expected. Most of the area will be uninhabitable for weeks, perhaps longer.
People living in mobile homes are especially at risk for injury and death. Even anchored mobile homes can be seriously damaged when winds gust over 80 mph.
