Trent Aegir Predictions 2021

TAKE CARE
The River Trent has steep banks – ensure that you take care of your personal safety and donot take risks trying to get a good view.

The Trent Aegir, also known as the Eagre, is a tidal bore on the River Trent. At certain times of the year, it is possible to see a bore of up to five feet high.

The Aegir occurs when a high spring tide meets the downstream flow of the river forcing it back and causing a wave to flow upstream. Typically it is possible to see the bore from Derrythorpe to as far up the river as Gainsborough. Beyond Gainsborough the bore is reduced to a ripple.

The best places to see the Aegir are at Gainsborough, Morton, East Stockwith, West Stockwith, and Owston Ferry.

The appearance of a bore can be affected by various other factors that may enhance or detract from the size of the bore;

  • excessive flood water flowing down the river will reduce the size of the bore
  • too little water flowing down the river will also reduce the size of the Aegir
  • depending on the wind direction winds may enhance or detract from the size of the Aegir
  • lighting may also affect how the Aegir is perceived – in my experience, it looks best when the sun is behind the river
  • depending on the weather conditions the Aegir can be up to 30 minutes earlier than predicted.

To help me improve my predictions I should be grateful if you could email me (angus@townley.com) with details of actual times and appearances of the Aegir. Don’t forget to say where you were. Many thanks.

Also please feel free to share photos and reports of the aegir below.

BEAR in mind that these are predictions and natural phenomena do not work to an exact timetable and for the reasons listed above the Aegir can arrive up to 30 minutes earlier than predicted. Be early to increase your chances of seeing it.

Please do not take any risks when trying to view the Aegir and don’t forget to abide by any Covid-19 precautions.
