Fecamp, lying in a valley close S of Point Fagnet, is a small port with facilities for commercial vessels, fishing boats, and pleasure craft. The harbor consists of Avant-port, Arriere port, Bassin de Mi-Maree, and two non-tidal basins.With winds from the W through N to NE, visibility is very good, and even in rainy weather, loss of visibility is only temporary.
With strong winds from the SW through N to NE, especially with an ebb current, a dangerous bar forms between the jetties, which may at times completely block the entrance. The effect of a strong swell is felt in the entrance channel, but gradually weakens in Avant-port and Arriere-port.
Winds from the ENE through S to WSW, may result in reduced visibility, especially in cold weather.
Tides at the port rise about 8.3m at MHWS and 6.8m at MHWN. Off the entrance jetties, the NNE flood current runs from about 4 hours before HW at the harbor until HW. The SSW ebb current starts about 30 minutes after HW at the harbor. The flood current may attain a rate of 2.9 knots at springs.The ebb current is weaker. At about 140m within the jetty heads, the currents flow with the channel. Both currents attain rates of 1 knot at springs and 0.5 knot at neaps.
