Baja got nailed with a hurricane and the southern tip won't be at it's best for a while.
Do what you want but I live in La Paz down near the tip. Yes the hurricane was hard on us but you'll never see a greener lusher Baja than this year. If you want to see Cabo at it's best and you like tourist resorts - then by all means wait until all the hotels and shops are fully rebuilt.
But if you want to see the most spectacular desert blooms and the greenest Baja hills ever this year is like no other I have ever seen. The roads are passable and things look pretty darn good. The whale sharks are in the Bahia de La Paz already and the snorkeling is amazing because the water is warm and crystal clear.
