This year has been very bad for crossing the Gulfstream between Florida and the Bahamas.
Due to the constant (since November) and strong north winds, the gulfstream has somewhat been slowed down in its northerly course during the higher wind speeds .... and when the N wind does briefly die down a bit the 'flow' seems to be accelerated.
The accelerated northerly stream flow during 'mild winds' is causing the waves to be much higher than 'normal'.
Typical is to NOT cross the Gulfstream in the Straights of Florida during ANY *north component* (NW, NNW, N, NE, NNE) wind of Force THREE or more - dangerous. This year, even the heartiest of trans-ocean sailors are turning back (to FL) from midstream due to the apparent flow/current variations. Ive been 'waiting it out' in the FL Keys since mid-January; Im waiting for the wind flow patterns to get back to 'normal' (easterly).
Most of the harbors in the SE (Georgia through Florida) are supposedly 'choked' with boats waiting to cross to the Bahamas and beyond. Almost no one has left to cross the Gulfstream in 2 months .... because of the frequency and intensity of the gales, the sea states, and because the 'weather windows' are usually only open for 24 hours - plus there are few anchorages in the southern Bahamas in a North wind.
As long as the current El Nino keep sending LOW pressure across the ITCZ and such HIGH pressure continues over the USA, the frequency of gales and low pressure centers continue to march across the Gulf of Mex. ......, methinks you will have a very difficult time crossing the 'stream' anytime soon.
