I fly out of Homer and can say that the airport has had a lot more days with the wind blowing from 40 degree, NNE than normal since the beginning of the El Nino three summers ago.  We know the water is got warmer in the Gulf and Prince William Sound, and the reds were later than normal.  Perhaps now that El Nino has passed things will get back to normal with SW 230 degrees winds dominating the Spit, more usual direction for sand deposits.  The Spit was there before mankind, it will be there long after we've gone.  Love it or hate it, the Spit means prosperity for Homer.
