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 Great Blasket 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.

Blasket Sound Tides
The tide starts running North at Dover –0120 or Cobh +0430
The tide Starts running South at Dover +0440 or Cobh –0035
Tides in the Blasket Sound twist with the channels, flood North, ebb South, and turn approximately half an hour ahead of the local HW and LW. The speed of the tidal streams in the main channels varies but is generally 1 – 3 kn (on springs) causing overfalls and eddies. Sustained southerlies make the flood run for longer and stronger.
