You Long Islanders must be in some sort of rain shadow! We have that on the Olympic Peninsula, the town of Sequim (pronounce Skwim, rhymes with swim) is along the Straits of Juan de Fuca and hovers in the shadow of a mountain or something, gets lots of sun...
Actually, that is quite nice! So close to the ocean as you are, and getting so little rain. I didn't even keep my LI weather reference, just ASSUMING that EVERYTHING I get through Google is UTTERLY reliable...
