What's New in Big Buoy

1.6

September 25, 2026

New • Spot alerts can now trigger on tide height. Monitor flood tides • The 7-day outlook shows each day's high tide and marks the biggest in the window. Fixed • The tide height slider is now easy to grab and drag. • Fish Activity now counts from the new and full moon correctly. • Saved spots: the forecast strip no longer overlaps the row above it. • Forecasts now follow the spot's own day, not your phone's time zone. Improved • Buoy readings say when they were actually observed. • Tide predictions name the gauge they came from and how far away it is. • Wind and wave charts name the model on the bars and when the data arrived. • Ocean overlays say which day's imagery you're looking at.

Awesome for figuring out where to go fish. Even better to pull up when they are biting to see what they are biting.
