I agree on the sunshine thing...i normaly fish shade if possible with the exception of this time of year,i fish shallow mud flats that really warm up in the afternoon and always catch fish in less than 8' even with the water temps in the low 40's,i always start at daylight and i have to fish closer to the channel and deeper till the sun warms for a couple of hours then i move to the shallow flats where the sun has warmed the water and usually clean up on em.
