Deciding whether to sail is mostly a weather question, so the forecast now lives inside Sailing Log, drawn straight onto the same nautical chart you plan and record on.
What you see
Open the Weather tab and the chart fills with wind arrows: each points where the wind is blowing, colored by strength on a Beaufort scale, with a translucent gust wedge behind it so you can see at a glance where it is gusty. Switch layers to see waves, temperature, or rain instead. Thunderstorm risk shows as a small lightning chip wherever the model flags it.
Three days, hour by hour
A time slider along the bottom scrubs the next 72 hours in one-hour steps, labeled by day and date, with the night hours shaded so you can see when darkness falls on a passage. Drag it and the whole map updates to that moment.
Tap for the exact numbers
Arrows give you the shape of the weather; tap any point on the map for the precise forecast there: wind speed and gusts with direction, wave height, period and direction, temperature, and rain, all for the time you have scrubbed to. It pulls a fresh point forecast for that exact spot.
Your trips, in context
Planned trips are drawn on the weather map, so you can line a route up against the wind before you commit to it, and pick the day that works.
Where the data comes from
- Wind, gusts, temperature, and rain come from the ECMWF global model.
- Waves come from a blended marine model with better coverage close to shore.
- Units are yours to choose: knots, m/s, km/h, or Beaufort for wind; °C or °F; meters or feet; mm or inches.
As with the charts, treat it as planning guidance, not a substitute for an official forecast: near-shore wave data in particular is approximate. It is there to answer the everyday question every sailor asks, can I sail, and when should I reef, without leaving the app you already keep your logbook in.
