The Aegir is a tidal wave that occasionally sweeps up the River Trent.
The Aegir is also called the Aegre and even Eagre. All are pronounced ager (a as in hay). On the Trent the leading edge of the tide coming in (the flood) can occasionally be a tidal bore of a few inches to five feet high, flowing up to Torksey or beyond.
There was one in late January. It was filmed by Reeds Coffee Shop in Gainsborough. You can see it by clicking here.
There is another video of it at Gunthorpe here.
The Environment Agency used to publish Aegir timetables, but have not done so for several years, however the Crowle Community Forum publishes predictions, click here.
Generally an Aegir only forms when there is a tide with a height of over 8.5 metres at Hull, no fresh flood water coming down the Trent and no wind. It is therefore not possible to predict an Aegir with any certainty.
