Predictions for 2020 are here<\/a>
https:\/\/crowle.org\/?p=4922<\/a> <\/h2>\n\n\n\n

NOTE! I have updated my predictions based on Today’s Aegir and a review of my approach – Please ignore previous versions of this table. Thursday 24th January <\/strong><\/p>\n\n\n\n

The Trent Aegir, also known as the Eagre<\/g>, 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. <\/p>\n\n\n\n

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<\/g> the bore is reduced to a ripple.<\/g><\/p>\n\n\n\n

The best places to see the Aegir are at Gainsborough, Morton, East Stockwith, West Stockwith and Owston Ferry. <\/p>\n\n\n\n

The Environment Agency used to publish predictions for the bore but no longer do. I have therefore tried to make predictions for the bore myself using tidal tables fro<\/g> the UK Hydrographic Office.<\/p>\n\n\n\n

I have used the tidal range at the Humber Bridge to determine the likelihood of a good bore – the larger the tidal range the more likely there will be a good bore on the River Trent. I have then determined timings using a time difference from the predicted high tide. The highest tides are around the spring and autumn equinoxes.<\/p>\n\n\n\n

The appearance of a bore can be affected by various other factors that may enhance or detract from the size of the bore;<\/p>\n\n\n\n
