Tide table

Monthly tide table

This tide table shows the times with the fastest speed of the current
in the Naruto Strait during the northward current (high tide) and southward current (low tide).

Information

  • The tide table shows the time when you can see the whirlpools best with a grace period of one and a half hours before and after the stated time. Depending on the weather, there are days where you cannot see the whirlpools even one hour before and after the stated time. On some days, you can see the whirlpools two hours before and after the stated time.

North （High tide）, South （Low tide）

It is when the difference between the high and low tides is greatest during the few days just before and after the new moon or full moon.

Check out the times with the whirlpools!
