The sea, hour by hour.
Down to 500m precision.
Wind, gusts, swell, sea temperature, and ocean currents for any point at sea. Pairing Apple Weather with Copernicus marine models that respect coastal geography.
Models That Respect Geography
Marine data routed dynamically from Copernicus to the sharpest model for where you float — from 500m in straits to global ocean grids.
Sea of Marmara Ultra-Fine Grid
Calculates intricate strait dynamics, Bosporus/Dardanelles surface and counter-currents, and micro-climate thermal wind shifts across enclosed bays.
Black Sea Hydrodynamic Model
Specialized for steep, short-period chop characteristic of the Black Sea basin. Tracks cyclonic rim currents and sudden cold-front squall developments.
Mediterranean & Aegean Model
Routes around rugged island topography. Models Meltemi funneling through the Cyclades and Dodecanese, afternoon thermal breezes, and katabatic headland gusts.
Copernicus Global Marine Model
Seamless coverage across the Atlantic, Pacific, Indian Ocean, and Caribbean. Tracks deep ocean swell trains, trade winds, and major oceanic boundary currents.
How MARLOG Forecast Works
Precision oceanic modeling combined with intuitive timeline indicators designed for active passage planning.
Reading the water on one screen
Combines air and sea temperature, wind speed and max gusts, swell height and period, a wind rose, 3-hour interval tables, sun times, humidity, visibility, precipitation probability, and UV index.
Colour-coded sailing windows
Scores each of the next twelve hours of wind against coastal sailing thresholds. Green highlights optimal sailing hours; amber flags moderate conditions; red warns of adverse sea states.
Autonomous 3-hour sea alerts
MARLOG checks your vessel’s home harbour every three hours against Copernicus and MET Norway feeds, notifying you when swell or gale-force gusts turn rough.
Know When to Cast Off
Test live coastal locations and scrub through the hour-by-hour timeline to see wave heights, gust ratios, and departure suitability ratings.
Marine Physics, Not Generic Land Weather
How MARLOG Forecast provides the hydrodynamics skippers need before leaving port.
