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 Simmy Island'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.

This tool can be used to estimate future costal tidal streams for this area. All that is required are two simple steps:
Step 1: What is the Dover High Water for the target date?
Use a current Dover Tide Table to find Dover High Water for the target date. The National Oceanography Centre offers online tidal predictions for up to 28 days from today. Click here to open their tide table for Dover
Step 2: Input the target date's Dover High Water
Taking a mean tidal offset from Dover's tide, we expect your targetted date's associated local tide at to be:
High waters: Low waters:
Data based on an average tide is only accurate to within one hour, if you more precise times are required use the ISA tidal predictions, with Strangford offset -01:00.

Headline: Thursday showery. Winds significantly lighter than Wednesday.
This Evening and Tonight: Showers and any longer periods of rain clear through the evening leaving a brief dry period before a band of further showers tracks east in decreasing wind later. Minimum Temperature 5C.
Thursday: Feeling milder with lighter winds than Wednesday. Showers mixed with brighter spells. Outbreaks frequent during morning, heavier for the afternoon, bringing the chance of thunderstorms. Maximum Temperature 12C.
Outlook for Friday to Sunday: Sunny spells and scattered showers in mild conditions through much of Friday and Saturday becoming dry with increasing sunny spells from Sunday afternoon.
