Which one is right?

The NWS Ocean Prediction Center forecasts the gulf stream for the West Palm Beach region at an average of 3knots anytime

Passage Weather forecasts of the gulf stream for the same region is an average of 1.5 to 2knots

NWS Environmental Modeling Center reads an average of 1.5 (m/s)

Anyone knows which one is right? there is a big difference from 1.5 to 3 knots current to calculate your course to steer across to West End

What time of year? It runs faster in the Fall and slower in the Spring.

Re: Which one is right?

It's a forecast. Forecast. That word is basically a synonym for "wild guess." And as currents go, the difference between 1.5 knots and 3 knots is pretty minimal. It can vary that much in a matter of days. I know, it's not so minimal for your boat, but the current really doesn't care about your boat.

So, neither is right and neither is wrong. They are just different forecasts. On the morning of your planned departure you will have to check actual conditions, and make adjustments based on that. In the end, once you get out there, it will be what it will be, and you will just have to deal with it.

Good luck.

Re: Which one is right?

The average also figures in the difference between current speed at depth vs. at the surface.
