IslaBuHow do the tides work in the Canary Islands?
In the Canary Islands there are two high tides and two low tides a day, roughly six hours apart. The difference in water level ranges from about one metre to more than two metres, and it is clearly noticeable on beaches and in natural pools.
Two high tides and two low tides a day
About 6 hours and 12 minutes pass between high tide and low tide, so the times shift by roughly 50 minutes each day. The biggest differences in water level come around the new moon and full moon (spring tides), the smallest around the Moon's first and last quarter.
Why it matters on the beach
At high tide beaches get narrower and some small coves almost disappear. At low tide, on the other hand, rocks and sand are uncovered, the water's edge is further out and it tends to be shallower near the shore.
Natural pools
Natural pools (charcos, piscinas naturales) are usually calmest around low tide. At high tide and in a bigger swell, waves wash over the edge and swimming can be dangerous, even when the water inside looks calm. During a coastal warning, do not go into them at all.
Tide times in IslaBu
For every beach we show the next high tide and low tide. We calculate the times from a sea-level model and they are approximate, accurate to about half an hour. For sailing and fishing, use the official tables.
