when does high tide occur

High tide occurs when the sea level at a coast reaches its maximum height in a tidal cycle, which usually happens about twice each lunar day (about every 12 hours and 25 minutes), but the exact clock time depends on your location and the date.

Quick Scoop: Core Idea

• High tide is the point in the cycle when the water stops rising and is at its highest level before it starts to fall again.

• Most coasts get two high tides and two low tides in about 24 hours and 50 minutes (a lunar day), so high tides are roughly 12 hours 25 minutes apart.

• There is no single universal “high tide time” – it changes with location, coastline shape, and local conditions.

What Makes High Tide Happen

• The Moon’s gravity pulls on Earth’s oceans, creating tidal “bulges” of water; as Earth rotates, coasts move in and out of these bulges, giving high and low tides.

• The Sun also contributes to tides, and when Sun and Moon line up (new and full moon), you get higher “spring” high tides; when they are at right angles (quarter moons), you get weaker “neap” tides.

• Local factors like bay shape, sea-floor depth, and currents can shift both the exact time and height of high tide from place to place.

Typical Timing Pattern

• Because Earth takes about 24 hours 50 minutes to rotate relative to the Moon, your high tides do not repeat at the same clock time each day; they are roughly 50 minutes later each day.

• A common pattern on many coasts is:
  • High tide
  • About 6 hours 12.5 minutes later: low tide
  • About another 6 hours 12.5 minutes later: next high tide

• Some places have different patterns (one main high tide per day or mixed patterns), so the schedule depends on your region.

How To Know Today’s High Tide Time

• For an exact time, you need a tide table, tide app, or local tide-forecast website for your specific location and date.

• These services use long-term observations and models to list the precise clock times and heights of each day’s high and low tides for thousands of stations worldwide.

• As an example, a coastal location like De Haan has published tables that show multiple specific high-tide times and heights for each calendar day.

TL;DR: High tide happens when the sea reaches its highest level in the tidal cycle, usually about every 12 hours 25 minutes, but the actual time depends on your exact coastal location and the date, so you check a local tide table or app to know “when” for today.
