My go-to app for sailing forecast

I find SailFlow provides the most accurate wind prediction for the Chesapeake Bay.

Pretty good

It’s works pretty well the future wind forecast is nice but it’s annoying you have to pay money to get all the wind stations.

Cannot access

The weather app does not populate. All that I see are settings to upgrade. I upgraded and still no app function. I have since discontinued my subscription out of frustration with Sail Flow!

Fantastic

I’ve used it for a couple or three weeks and it is pretty accurate also it updates hourly so between times it is often constantly changing and updating.
One of their stations is close by and it’s a marine one. So it has been pretty accurate for us!

Great Wx app

My favorite!
