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 Christchurch Bay'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.

The tidal range of Christchurch Bay is the lowest along the south-central Channel coast. At the entrance to Christchurch Harbour, the mean spring range is 1.4 m, reducing to 0.8m during neap cycles. The duration of the flood tide is 6.4 hours, whilst the ebb phase occupies 6.01 hours. Mean tidal range within the harbour is lower than on the adjacent open coast because of attenuation effects set up by The Run. In both Christchurch Bay and Harbour, a "double high water" effect is discernible. This contributes to the ebb-dominant asymmetry of the tidal regime of Christchurch Harbour.
Streams are weak inside the line Handfast Point to Hengistbury Head and in Christchurch Bay running generally in the direction of the land. Rapid tidal currents are restricted to the eastern extremity of the bay, except for Christchurch Harbour entrance, where ebb flow coupled with fluvial discharge can create maximum velocity currents approaching 7 kn. The east stream sets towards Christchurch Ledge and the Shingles. It is very strong and overfalls can be expected during Springs. Christchurch Harbour has a double high water. At Springs, the first high water tends to be higher than the second, whereas at neap tides the second high water is higher than the first.
There is approximately a ½ hour difference between high water at the entrance or outside and at the town quay. During periods of high pressure the depth of water could be reduced by more than 30 cm. With a normal range of only 1.2 metres, this can dramatically reduce the available depth.

Headline: Patchy fog clearing to bright or sunny spells.
Today: Any early fog patches will lift by mid-morning and whilst there will often be large amounts of cloud, there will be some bright or sunny spells. Just a small chance of an isolated light shower. Maximum Temperature 17C.
Tonight: Dry with clear spells this evening, then clouding over with rain spreading in from the west, giving most places a wet end to the night. Becoming breezy near the coast. Minimum Temperature 11C.
Sunday: Cloudy with outbreaks of rain and drizzle though Monday morning and foggy over higher ground. Remaining cloudy and damp during the afternoon, but with the breeze easing. Maximum Temperature 17C.
Outlook for Monday to Wednesday: Changeable conditions will prevail over the next few days with spells of wet and windy weather interspersed by some drier interludes. Generally mild by day and night.

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 they have helicopters based at rescue bases in 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 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.
