the Lune Bore is a tidal bore on the river Lune, much like the tidal bores on all the west coast rivers, I may check out the Ribble Bore this week end and of course the Kent Bore, AKA the Arnside bore by the locals because it makes so much noise getting through the railway viaduct across the Kent at Arnside, I have spoken to people fishing on the ribble who assured me they see the ribble bore from time to time.
I first saw a river bore in the early twenty hundreds (2000) as we were camping on a hill next to the river Severn, it was only when I moved to Lancaster, and then having been a resident of Preston for ten years, that I first saw the lune bore while cycling to Morecambe on the old electric train line to morecambe and heysham on my bike, that I spotted what looked like a wave coming up river as I passed under Carlisle bridge, at some point I became convinced it was a wave and about turned and followed it to green ayre, after which I did a lot of googling to find out about it.
I now use "easytide" from UKHO who do tide tables for shipping etc, they give you today and for the next seven days the tide times, thats high and low times for all ports, I use Heysham as the lancaster times are incomplete being an ex port and way above chart datum, sort of average sea level.
So when I notice on the calendar that a Full or New Moon is due, I refer to the time for high tide at heysham and get down to river two hours before, it usually gets to Snatchems(The Golden Ball Inn) one and three quarter hours before High tide, well, it gets there a bit sooner but it is one of the high spots of the river bed which holds up the progress of the tide untill the level gets to the point where it can continue up river, at that moment is when you see waves or a wave appear at the shallows at Snatchems.

Ifound that the bore arrives at Snatchems (outside the golden ball inn) about two hours before High Water at Heysham. that is another high point and the tide takes ten mins to fill up and over the step, (the bedrock is near the surface there.) it then becomes visible about 50 yds down river from there unless it is a really good one, it then takes about 25 mins to get to green ayre, it disappears on the wide deep places , reappears in the shallower places, quite fascinating.
Tomorrow the 11th Aug is the new Moon, the spring tides run till tues/wed, they also run at night at a higher tide than in the day, the bore is at least in places , visible every day at the moment as the water level in the river is at an all time low due to recent drought conditions, albeit just about visible, normally it is only visible at the full or new Moon for the 4 or 5 days aroud the full/new Moon.
Tomorrow, the bore will gather at snatchems at 10am and reach Green Ayre by 10.30am, its a 9.8 metre tide, today was 9.4,
Tonight at 9.30pm at snatchems will be a 9.7 metre tide get down there, it will be more evident than today.
