San Diego climate (Koppen climate classification)?

Question

what is the San Diego's climate?

I hear someone said it is Mediterranean climate(Csb), but someone said it is a low latitude hot steppe climate (BSh).

Please tell me which one is correct!!or both are not correct?

Answer 1

San Diego has a (Csb) climate, although it seems to be right on the borderline; a little further south, (just past Tijuana), the climate transitions to Bsh.

This refers to coastal areas of San Diego, however. Inland, the climate must be (Csa) since it quickly gets hot when you move away from the coast.
