Thalassa turns professional ocean and weather models into a simple map and a friendly advisor for anyone who spends time on the water. REAL-TIME MARINE MAP See the Mediterranean come alive with animated sea-surface currents, wave height, wind, rain, cloud cover, pressure, temperature and water quality. Scrub the timeline — hourly near now, out to +10 days — to watch conditions evolve, tap any point for a detailed meteogram, and switch between layers with a single tap. • Sea-surface currents (animated streamlines) • Wave height, period and direction • Wind, air temperature and mean sea-level pressure • Rain and cloud cover, with sky symbols • Sea temperature and water transparency • Satellite and in-situ observations • Adaptive timeline: hourly near now, out to +10 days SEA ADVISOR — YOUR AI GUIDE Not sure where to go? Just ask. Tell Sea Advisor what you want to do — swim, kayak, surf, snorkel or sail — and it checks the live marine forecast to recommend the best spots and times along the coast, with clear safety notes (waves, wind, UV). TRUSTED DATA Forecasts come from Copernicus Marine (CMEMS), ECMWF and EMODnet — the same operational models used by scientists — delivered by CMCC, the Euro-Mediterranean Center on Climate Change. Thalassa is free, has no ads, and does not track you.

Verdict
The clearest difference is ads: Thalassa at none against Meteal's shown. Meteal's advantage is update cadence (every 3 days vs every 3 weeks) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
