You should check these events as they're in force for the safety of all harbour users and will help you make the most of your visit to Bristol Harbour.

Events in Bristol Harbour

30/22 Model powerboat race at Baltic Wharf - Sunday 9 October 2022

A model powerboat race will be taking place at Baltic Wharf on Sunday 9 October 2022. Racing will take place between 9am and 5pm.

A buoyed course will be laid out on the South side of Baltic Wharf, with general navigation being restricted to the North side. Mariners are requested to proceed slowly through the area

28/22 Restrictions to departures and arrivals due to low rainfall

From Monday 5 September, due to an exceptionally dry year and the current drought status, there is no longer sufficient fluvial flow to maintain harbour levels if normal locking services were to continue.

Until further notice, the harbour authority will be considering maintenance of the harbour level a priority and therefore will be asking Mariners not to book first lock departures or arrivals.

Any bookings through the Sail Bristol App for first locks will be contacted and asked to rearrange.

Locking throughout tidal periods will be subject to alteration at the duty Deputy Harbour Masters discretion. If this occurs, Mariners will be contacted accordingly.

A first lock may still be granted if there is significant demand or need but only at the discretion of the Harbour Master.

26/22 Large tree blocking section of River Avon - proceed with caution

From Wednesday 17 August, a large tree is obstructing the River Avon approximately half a mile downstream from Hanham Weir.

Navigation is possible, but proceed with caution. An update will be issued when the tree has been removed.

23/22 Redcliffe Bridge navigation restriction update

From Monday 19 September to Sunday 13 of November, the navigation channel under Redcliffe Bridge will be narrowed.

This is because of the positioning of a works pontoon on the West abutment to facilitate the ongoing renovation.

Mariners must navigate with caution.

18/22 Entering Bristol Harbour via Junction Lock

All Mariners entering Bristol Floating Harbour via Junction Lock should exercise caution when passing the first set of stop gates. Both gates are not fully recessed due to a build up of silt.

Cumberland Basin Locking procedures will be changing from 1 July 2019 until further notice.

This is so harbour staff can be more effectively deployed. You must give a minimum of 48 hours' notice if locking operations are needed between these hours, so we can ensure docking staff and bridge operators are available.

  • Call the Docking Deputy Harbour Master: 0117 9273633

  • Call the Bristol Harbour office: 0117 9031484
  • Call emergency control: 0117 9222050

27/17 Plimsoll Bridge Swing

With immediate effect from 31 March 2017 a 48 hours' notice is required for a Plimsoll Bridge swing.

The Deputy Harbour Master can be contacted on 0117 927 3633 and between tidal watches a message can be left on the answering machine.

This restriction will remain in force until further notice.
