Weather routing for sailing

All the latest forecasts. Your route in seconds.

Every new run of every weather model reaches Saily WR as soon as it is published. Draw your trip: every model covering it, from AROME to ECMWF, gives its route in seconds, in the wind and the current, clear of the coast and the shallows.

How it works

Know which way to go, and when you'll arrive

Three steps, and the fastest route in each weather model is in front of you: how long it takes, when it arrives, and the fuel if the wind drops.

Describe your boat
Its polar, its performance and its engine, once and for all.
Draw the trip
Two clicks on the map, start then destination, and the departure time.
Decide
One route per model, side by side: you see where the forecast is solid, and where it wavers.

Decision support

Leave, wait or go another way: decide with your eyes open

A single route can't tell you whether the forecast will hold. Saily WR sets every model side by side so you can judge for yourself: it informs your decision, and the decision stays yours.

Where to sail?

Every model covering your trip gives its route, on its latest run, in seconds. Where they overlap, the forecast is solid; where they part, you know where to keep an eye on the sky.

Which model to believe?

The Most precise badge marks the model with the finest grid, and a bubble tells how many models arrive together: “5 of 6 models arrive between 14:00 and 16:00”. Signed in, let an AI briefing compare the routes for you.

ExperimentalSet the wind you read on board against every model.

When to leave?

Move the departure time earlier or later: every route is computed again in seconds.

ExperimentalThe best departure among 24 over three days, each one rated ✓, ! or ✕ against your own limits for wind, gusts and waves.

Also experimental: your boat followed on the map. Free for now, for an account, on request: write to contact@saily.io or on Instagram. What the experimental features do →

Your boat, not another one

Its polar among nearly 22,500, including those of 21,778 boats from their ORC certificates (2019 to 2026), and its performance as a percentage: a foul hull, tired sails or a short-handed crew. It stays saved in your browser, or in your account if you sign in, to find it on any device.

Always in open water

On the bathymetry, the route avoids water shallower than the minimum depth you set (your draught plus a safety margin), and sails round the land as OpenStreetMap draws it.

The current on your side

The route seeks out a fair current and keeps away from a foul one, tide included with SMOC and the regional models. Speed over ground and the miles gained from the current are shown for each route.

The engine when the wind dies

Below the speed of your choice, the engine takes over. Engine hours and fuel are estimated, and the motoring legs drawn on the map.

The wind all along the trip

Wind barbs along the route, curves of the wind and of the boat speed: you know what lies ahead before you cast off.

A route that explains itself

The isochrones are shown on the map, so you can see why the route goes where it does; the time step and the grid are fitted to each trip.

Coverage

Anywhere in the world, right down to your home waters

Wind, current, coastline and depths cover the whole planet, from an ocean crossing to a short hop between two harbours; and wherever finer data exist, your route makes use of them.

The bar shows how fine each dataset is, from 25 km down to 10 m.

Wind

Every model covering your departure and your destination computes its route: the global ones anywhere, the finer regional ones over their area.

World≈ 25 km

The global models, from GFS (≈ 25 km) to ECMWF (≈ 10 km): any trip, all the way offshore.
Europe≈ 7 km

ICON-EU (≈ 7 km) and ARPEGE-EU (≈ 10 km), over Europe and the north-east Atlantic, the Mediterranean included.
United States≈ 3 km

RRFS, from NOAA: the coasts of the contiguous United States, Puerto Rico and Hawaii.
French overseas≈ 2.5 km

AROME Outre-mer, in the West Indies, French Guiana, the Indian Ocean, New Caledonia and French Polynesia.
Northern Europe, Italy≈ 2 km

ICON-D2, HARMONIE DINI and ICON-2I, from Iceland to the Baltic and the Adriatic.
France≈ 1 km

AROME France, the finest of the regional models, from the southern North Sea to the western Mediterranean.

Current

The surface current carries or slows each route: it sails in SMOC. In eight US coastal areas, NOAA's regional models take over by themselves, AMM15 on the European shelf and MedFS in the Mediterranean.

World≈ 9 km

SMOC, from Copernicus Marine: hourly, with the tide and the drift of the waves, over 10 days.
Mediterranean≈ 4 km

MedFS, by itself, in the Mediterranean and off Portugal and Galicia, over 10 days: a finer current wherever it has water, tide included, over SMOC.
European shelf≈ 1.5 km

AMM15, by itself, on the European shelf (the Channel, the North Sea, around Brittany…), over 7 days: fine tidal currents wherever it has water, over SMOC.
US waters≈ 250–1000 m

NOAA OFS, by themselves, in eight US coastal areas (Salish Sea, Chesapeake, San Francisco Bay…), over 48 to 72 h: fine tidal currents wherever they have water, over SMOC.

Coastline and depths

The route avoids water shallower than the minimum depth you set, and the land as OpenStreetMap draws it.

Europe, eastern Caribbean≈ 115 m

Elsewhere≈ 460 m
