Small tidal stream inaccuracies can develop when advancing beyond HW Portsmouth +6. Because of this we only enable today's tidal stream chartlets to advance 24 hours. Future tidal planning is best accomplished by using Mercury Yacht 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.

Standard Port Southampton Mean Tidal Ranges Springs 4.0m; Neaps 1.9m.
During Springs High Water Warsash, at the head of the river, is 10 minutes after HW Southampton and Low Water is the same as LW Southampton. During Neaps High Water Warsash is 20 minutes after High Water Southampton and Low Water is 10 minutes afterwards.
Double High Water occurs at or near Springs and there is a stand, which can last as long as two hours, at other times. Estimates presented are for the first High Water during Springs or the middle of the stand outside of this.
Helmsmen should note the double high tide or stand means the ebb tide has to complete its cycle in 3-4 hours instead of the usual 5 + hours. This means that the rate of the ebb will be significantly greater than the preceding flood tide. This rate could also be increased by land water, after heavy rain, flowing in the river. Be very careful moving into complicated berths on the ebb. Where possible it is best to entirely avoid berthing manoeuvres on the first flush of the ebb especially so during Springs.
Feel free to use our calendar, below, to predict 'Future Tidal Streams' as normal. These are displayed in local time and need no adjustment.
