No these are the same times ..if you switch from GFS to Nems the time remains the same in the bottom bar ...as I mentioned , often there is a BIG difference....
Is the NEMS likely to be more accurate, even though their update interval is much longer , so the GFS could actually be more recent ..I'm looking at one right now where the GFS was updated 5 hours ago, but the NEMS is 19 hours ago .....
How do we know which one to trust to be more accurate...the later one (GFS) or the one with a smaller forecast area?

I keep my boat at Estepona, Spain..love your product , but am confused why there is such a HUGE difference in wind direction and speed between the 2 types of forecast available in my area... the 2 pictures show the situation right now..
which one should I be trusting?

thanks in advance !
