a bit rainy even at times, no direct sun at all

With a 60 F air temp and a nice breeze I couldn't resist taking the windsurfer out on the lake.  I still only have the neoprene booties (and a swimsuit and a lifevest) and the water temp has to be below 50F at this point.  I managed to sail across to port in a light medium breeze to the shore there where I hopped off in shallow water and sat to take a break for a bit and catch my breath (it's been a long time (months) since these muscles have been worked at all).    The last little bit sailing up that shore had the feeling of being possible to creep right up along the shore upwind the way the wind was coming across from the right.  After a short break I got back out and made a bad enough mistake to send me into the drink.   At that moment (and for about 5-7 seconds until I got out from under the sail and back up on the board), I had a strong feeling of "this isn't fun at all anymore".  And with the bone-chilling sensation of that water (such that the wind blowing my body dry was a "warm" sensation on a cloudy late November afternoon) I suddenly got a pretty good charge of adrenelin which really seems to clear my mind and make me find sailing skills that I didn't realize I had.  Shortly after coming up, I made another mistake and had mentally prepared myself to hit the water when the wind somehow bailed me out (and instead of falling over, I was able to somehow maintain my balance).  The clarity of my good fortune suddenly combined with the adrenelin to make me switch to a much more stable way of sailing.    When the wind blew too strongly, I was able to hold on tight to the mast (or the uphaul) and just wait it out.  But as I recovered, I got sailing into a very very strong wind and had the interesting dillema of "needing" to sail down-wind more, but due to the high windspeed, finding that quite hard to do.   The higher windspeed seems to make a slightly upwind tack the "natural" (or easiest) way to sail.   By leaning slightly more sharply into the wind (and being able to read the minute fluctuations of the gust (or alternatively find a place with more constant wind than this lake) is something I have more learning ahead of me on).  But even steering to a "dead" reach and then beyond (towards a jibe) becomes quite tricky in a high wind.  I find I'm able to sustain a couple seconds, but invariably that position becomes unstable and I naturally switch back to a more "reach-like" position which steers the board back upwind immediately as a result and I have to then again attempt to turn downwind.  I guess I'll know I've truly reached another level when I can "intentionally" slalom back and forth link that in a really high wind.   Anyhow, after hitting the shore much farther upwind than I put in (on the 5 minute sail after I'd fallen in out in deep water) I just came out of the water and stripped off my lifevest and tried desperately to gulp some oxygen.  After that immediate crisis was over, I had another 10+ minutes of excruciating (but good) pain in my forearms to wait out.  After recuperating, I went back out a couple more times (resting on the beach at intervals) and really had an incredible time (and didn't fall in again).   Only an hour or so total, and the intense amount of energy it takes to sail in a high wind (it's almost an anerobic sport for me (at least until I get a harness that works)) meant that the water temperature wasn't really much of a problem.   Still it'd be nice to get a wetsuit and gloves so that I don't have to limit myself to days when the air temperature is at least 60F.
