NB: The Severn Bore has been known to
arrive up to 20 minutes early or 30 minutes late depending on
prevailing weather conditions. Make sure you get there early to avoid
disappointment,
The Severn Bore has been known to reach two metres in height.
Its average speed is 16km per hour.The Severn Estuary experiences the
second highest tide anywhere in the world, and the difference between
the lowest and highest tide in any one day can be more than 14.5
metres. High or spring tides occur on several days in each lunar cycle
throughout the year.
The size of a bore can also be affected by
opposing winds or high freshwater levels which reduce its height and
delay its time of arrival, whereas a following wind can increase its
height and advance the time it arrives. There is no true Severn Bore
upstream of Gloucester because of weirs on the twin-armed channel near
the city.
Where to see it...
A convenient vantage point for the bore
is Telford’s bridge at Over but the bore is at its most spectacular on
the section of river between Minsterworth and Lower Parting. Some of
the best viewing points are:
Newnham-on-Severn
Standing
in the churchyard on the high cliff gives a view of a three or four
mile stretch as the bore negotiates the Horseshoe Bend.
Minsterworth
The road is right beside the river and river access can be gained at the Bird-in-Hand, by the old ferry or at the church.
Lower Parting
Where you can see the bore split into the two river channels.
Manor Ditch
¾
mile downstream from Lower Parting you can see the bore, perhaps as
much as ten feet high, racing around the outside of the sharp river
bend.
Maisemore Bridge
Here there is the added
interest of the reflex wave, maybe as high as a foot, flowing back down
river 10 minutes after the bore has encountered the weir.
Whichever
vantage point you choose, you are likely to be astonished by the sheer
power of the water, the increasing roar as it approaches and the
dramatic change in river level once the bore has passed.
