Small tidal stream inaccuracies can develop when advancing beyond HW Dover +6. Because of this we only enable today's tidal stream chartlets to advance 24 hours. Future tidal planning is best accomplished by using Weymouth Harbour's future tides predictor below.
The above image represents the current tidal streams offshore of this haven. Streams attaining three knots and above are highlighted by red arrows . All times are in local time with red text indicating springs, blue indicating neaps and gray between tidal events. Click [+] to advance the estimate by an hour and click [-] to step back.

Arrows represent the direction of tidal streams with lighter or shorter arrows indicating weaker streams. Stronger streams are indicated by heavier or longer arrows, and as mentioned above, red arrows flagging rates of 3 knots and above. Numerals represent [mean neap, mean spring] rates in tenths of a knot. For example the numbers 12,23 would indicate a mean neap of 1.2 knots and a mean spring of 2.3 knots.

Mean Level 1.0 Double Low Waters occur between Portland and Lulworth Cove. Predictions are for the 1st Low Water with the 2nd Low Water occurring 3 - 4 hours later.
Tides in Weymouth are very small, by Channel standards, and tidal streams are so weak that they are barely perceptible. Owing to an eddy, there is a west-going stream in Weymouth Roads that is never more than a ½ knot save for between Dover -0515 to -0315. Tides flood for 4 hours, ebb for 4 hours and then there are 4 hours of slack around LW, except for a small rise of around 0.2 metres, known as the Guider, that commences about ¾ of an hour after Low Water. The rise and fall of the tides within the harbour may be considerably affected by winds.
Tides in the vicinity of the Bill of Portland are strong, and a dangerous Race exists south of the Bill. The peninsula disrupts the flow of water in the Channel and the streams are further disrupted by a ledge of Portland stone that extends further out to sea. Added to this are strong south-going streams either side of the Bill, running for 9 or 10 hrs of the tidal cycle, that meet the main Channel streams. All combine to cause the seas to well up and break with the effects of this conflagration being felt up to 5 miles south of Portland Bill.
The Race can be avoided by staying 3 to 5 miles offshore and allowing for a strong set into the race or onto the Shambles. Those planning on visiting Weymouth from the west can make use of an inshore passage which is much faster and shorter. Timing is vital to catch slack water and the right weather conditions in the inshore passage, but it should not be attempted during Springs or at night.
Feel free to use our calendar, below, to predict 'Future Tidal Streams' as normal. These are displayed in local time and need no adjustment.

Headline: Sunny spells and heavy showers. Turning drier later today.
Today: Some sunny spells, but plenty of heavy showers from early in the day. Hail and thunder is possible in some of the downpours for a time, especially further east, before showers ease from the west later. Breezy. Maximum Temperature 17C.
Tonight: A drier evening with some late sunshine and then clear spells to start the night. Turning windier and cloudier with patchy rain reaching western areas after midnight. Minimum Temperature 6C.
Wednesday: Cloud and outbreaks of rain continuing east across all parts, followed by a few afternoon showers, then sunny spells to end the day. Notably blustery for the time of year. Maximum Temperature 18C.
Outlook for Thursday to Saturday: Remaining breezy on Thursday with some patchy rain. Largely dry on Friday, with some sunshine, though cloud may linger in the far southwest. Fine, sunny and warmer on Saturday.

Contacting Coastguard and Emergency Services
Coastguard should only be used for distress and urgency calls as follows:
The National Maritime Operations Centre (NMOC) based at Fareham handles all operations in the area from Sussex, Hampshire, Isle of Wight, Dorset and Devon. They also assist other authorities such as the Police, Fire and Ambulance with their specialist expertise. The centre is manned 24x7 and has helicopters, based at rescue bases at Portland or Lee-On-Solent, at their disposal. Ch.67 can be used for routine communications and the National Maritime Operations Centre can be contacted directly on +44 23 8032 9486 for administrative enquiries only.
Phone 999 when it is a Police emergency, such as when a crime is in progress, someone suspected of a crime is nearby, when there is a danger to life or when violence is being used or threatened. Phone 101, the police non-emergency number, when it's less urgent than a 999 call.
