The video was taken on the North bank of the river Dee besides the blue bridge in Queensferry. The river level was low and there was no wind.
Considering the tide height, the bore was disappointing. In fact, the bore is a shadow of its former self, especially over the past year or so. It may be that the river has been dredged, resulting in a much diminished bore.
The Cop park in Chester offers an uninterrupted view of a long straight section of the river as it enters the city. The bore consisted of small, hardly noticeable undular waves for most of its journey down this stretch. I attempted to film the bore arriving under the Grosvenor Bridge (carrying the A483) in Chester city centre, but arrived just in time to see the wave front pass before I could set up my camcorder.
