I've proably spent a couple months worth of time at DVB during November over the years. Generally early to middle of the month. It's been our experience that day time temps are great! 75-80F..at night it might get down to say the mid 50's....of course you're asking about "the weather" and it can vary ALOT...99% of the time the wind is coming right off the ocean, so if it's feeling cool, the wind can feel dramatic...this really is only a problem if you're in a beach cottage or on the beach. IF you have 'average luck', you'lll have fine weather.
