Batch runs
Conditions at many ports at once?
Pro runs this tool for every row of a CSV or a watchlist, up to 500 rows at a time, in the Voydar Terminal, and downloads the answers as CSV. Single runs here stay free. Try Pro free for 14 days, once, no card needed.
How this works
- Stations: NOAA National Data Buoy Center buoys and CO-OPS tide stations within 100 km of the port's position, nearest first.
- Readings: the buoys' own reports, refreshed twice an hour, in the units NOAA publishes (wind converted from m/s to knots).
- Tides: NOAA's high/low predictions for the nearest tide station, refreshed daily, 8 days ahead. Local effects and weather can move the real tide by a lot.
