Port Hercule de Monaco

Monaco-Ville / La Condamine, Monaco · 43.735°N 7.426°E

MEGACOORDINATEDOPERATIONAL

The principality's deep, breakwater-protected yacht harbour and the operational heart of the Monaco Yacht Show. Night entry is controlled, megayacht quays are scarce, and September occupancy is a planning problem rather than a berth search.

Busy-time intelligence

August: historical occupancy estimate 90% (ESTIMATED). VERY_HIGH in September (Yacht Show) and Grand Prix week Drivers: high summer Côte d'Azur traffic. A congestion band here is derived from event calendars + historical occupancy, not a live sensor count. Labelled ESTIMATE. This is an estimate derived from declared inventory and seasonal demand, not a live sensor count or a passenger-style headcount.

Explainable reliability

No harbour score. Each metric says why.

  • Berth pressureVERY_HIGHEstimate
    • Declared megayacht quay count is in the low teens
    • Show week reallocates the entire north basin

    Declared capacity vs event demand

  • Weather disruptionMODERATEEstimate
    • Easterly swell closes comfortable outer-berth use
    • Mistral is more a passage issue than a harbour issue
