Spring Tides at Réserve Sous-marine de Monaco

Spring tide schedule and tidal coefficients

Spring Tides at Réserve Sous-marine de Monaco

Spring tides at Réserve Sous-marine de Monaco in Monaco are among the most impressive natural phenomena on the coast. When the tidal coefficient exceeds 90, the sea retreats much further than usual at low tide, then surges back with considerable force at high tide, amplifying the 0.1m average tidal range.

These exceptional tides follow a predictable cycle tied to the alignment of the Sun, Earth, and Moon. Our spring tide calendar for Réserve Sous-marine de Monaco lets you plan ahead — whether for shore fishing, coastal walks, or simply watching the spectacle. Always prioritise safety during these powerful tidal events.

All About Spring Tides

What is a Spring Tide?

A spring tide occurs when the Sun, Earth, and Moon are aligned (at new moon and full moon), combining their gravitational forces. This alignment amplifies the tidal range: high tides are higher and low tides are lower than normal. A spring tide is defined by a tidal coefficient of 90 or above (on a scale of 20 to 120). The strongest spring tides, with coefficients above 100, occur during the equinoxes in March and September.

Activities During Spring Tides

  • Coastal observation — Even with small tidal variations, spring tides reveal subtle changes in water level and current patterns around Réserve Sous-marine de Monaco.
  • Photography — Capture the waterfront at its lowest and highest points for striking before-and-after comparisons.
  • Rock fishing — Slightly lower water levels may improve access to rocky outcrops for anglers.
  • Nature watching — Look for marine life in temporarily exposed shallow areas.

Understanding Tidal Coefficients

The tidal coefficient indicates the strength of a tide on a scale from 20 to 120. It is calculated by the French Hydrographic Service (SHOM) and determines the expected tidal range for each day:

  • 20-40 (Neap tides) — Minimal tidal range, gentle currents. Calm conditions for most water activities.
  • 41-69 (Average tides) — Moderate tidal movements. Standard conditions for coastal activities.
  • 70-89 (Strong tides) — Significant tidal range. Increased currents — check tide times carefully.
  • 90-100 (Spring tides) — Large tidal amplitude. Extensive foreshore exposed at low tide. Strong currents — caution required.
  • 101-120 (Exceptional spring tides) — Maximum tidal range. Very strong currents and rapid water movement. Heightened safety awareness essential.

Safety During Spring Tides

Spring tides at Réserve Sous-marine de Monaco demand heightened vigilance. The larger tidal range means faster-moving water and stronger currents. Follow these safety rules:

  • Check tide times before any excursion — Know exactly when the tide turns. Never venture onto the foreshore without consulting the schedule first.
  • Never turn your back on the sea — The incoming tide can surge in faster than you can walk, especially around rocks and in gullies.
  • Keep your phone charged and accessible — In case of emergency, call 196 (sea rescue) or 112 (European emergency number).
  • Inform someone of your plans — Tell someone where you are going and when you expect to return.
  • Watch for waves near sea walls — During spring tides, waves can overtop harbour walls and coastal defences without warning.
  • Supervise children closely — The foreshore can seem like a vast playground at low tide, but it becomes a dangerous trap when the water returns.
