From their site, to calculate tide times for:

  • Clevedon add 10 minutes
  • Portishead add 18 minutes
  • Burnham-on-Sea add 4 minutes

Easy Tide for W.S.M

Weston Bay is a large flat area which, on spring tides, dries almost to a line between Brean Down and Birnbeck from where the bottom falls away rapidly.

This line also marks the edge of the tidal flow which is ALWAYS clockwise in the bay, which means a constant flow westward along Brean Down. This can throw up quite rough seas in this area when the wind is in the West.

This tide stream can reach 4 knots.

The Eastern end of the Bristol Channel has the second highest tidal range anywhere in the world. It's actually the highest naturaly occuring tidal range in open waters, the other being due to a convenient restriction in a channel.

There are links here to several sources of information here, including a local table published by Somerset Council.

Water users will need to consider these factors before attempting to navigate the river, or when venturing out into the channel.

This is probably only of interest to those of us that insist on rowing.

The river can have a very strong 'up-river' flood flow on spring tides. Other times, at least with normal rain-fall, the incoming tide flow is weakened by the river. If the river gets depleted, then obviously the flood tide will have a greater effect.

There's very little in the way of 'slack' water.

When the ebb tide adds to a strong river flow, there can be 3 to 4 knots or more of current.

However, the wind can funnel up the river, so don't rely on a fair ebb flow to get you back to the pontoon from your mooring - in breazy conditions, it can be impossible to row against the wind. Be prepared to leave the boat on the river bank and walk back!
