Welcome to the West Coast
Wind at that time of the year is either hit or miss. More important bring a wetsuit, water temp will be in the mid 60ies. Average kite size is 12 - 14. Swell and surf is normally good (espclly with a storm off of MX or S-Pacific). Surf swell is from the south, wind swell from the west ...
I don't know if it's worth dragging your gear from coast to coast. If it all fits into a golf bag, it might be worth it. If you have to pay extra for your SB then probably not. If your buddies have a SB, then you are lucky or make new friends on CL to find a cheap one. Couple of 'schools' are renting boards, me thinks they are around 40bucks a day.
Note: Kiting the surf is in Cali officially not permitted, but often tolerated at this time of the year.
Malibu, HB and Ventura has an aggressive local tribe protecting their turf, so use some common sense and find a local for some briefing.
The rest is pretty laid back.
