How to Read the Tide Tables

Each day shows the time and height of each tide, in meters. The symbol ▲ marks a high tide and ▼ a low tide. The lower the height of a low tide, the more reef appears.

Generally, there are two high tides and two low tides per day. On some days there are only three, because the fourth tide occurs the following day. In December 2026, this will happen on the 4th, 13th, 20th, and 27th.

The times advance, on average, about 50 minutes per day, so always check the correct date. During the weeks of the new moon and full moon, the difference between the tides tends to be greater. Watch the explanatory video about the influence of the moon on the tides.

Natural Pool Days in December 2026

Here, we call the day when the low tide reaches 0,5 m or less between 7 am and 17 pm a "natural pool day." On these days, the reefs are exposed and pools form. In December 2026, there are 13 days, in two periods.

From December 6th to 11th (Sunday to Friday), the low tide of the day will be between 0,43 m and 0,50 m, and will occur between 7:45 am and 10:37 am.

From December 21st to 27th (Monday to Sunday), the daytime low tide will be between 0,26 m and 0,44 m, occurring between 7:13 am and 12:04 pm. The lowest tide of the month during daylight hours is on Thursday, December 24th: 0,26 m at 9:42 am, when the reef is most visible.

The weekend of December 26th and 27th falls on pool days, as does Sunday the 6th. The rule only considers low tides between 7 am and 17 pm, so those at night don't count.

How to Enjoy the Natural Pools and the Island Tour

If you're going on the Island Tour, check the low tide in the morning: the tour usually passes by the natural pools early in the day.

If you're going to any beach looking for a natural pool, low tide is worthwhile at any time between 7 am and 17 pm, not just in the morning.

Attention: if low tide is around 17 PM, there will be little daylight left to enjoy the pool. And, most importantly, returning to the sand in low light is dangerous: the risk of falling is high. Prefer earlier low tides. In December, no pool day has low tide around 17 PM: all tides occur between 7:13 AM and 12:04 PM.
