Wednesday 16 June 2027. Tides. The range here is 0.1 to 0.3 m: tides make no practical difference. Wind and air pressure move the sea level more than the tide does.
Giglio uses the Marina di Campo station.
Tide times are predictions made for this plan from the TICON-4 harmonic constants (DGFI-TUM) with the Neaps tide predictor, because the official 2027 tables were not yet published when it was written. Tested against the official APDL table for Leixões on 23 July 2026, the predicted times were within 8 minutes and the heights 0.1 to 0.2 m lower. Heights are above lowest astronomical tide. Check every time against the official 2027 table before sailing.
Daylight. Sunrise at Elba 05:41 CEST. Sunset at Giglio 20:55 CEST.

Settled in summer. Light winds and sea breezes.
