I'm planing on taking a vacation with my family in the beginning of April, to San Diego and LA Cal. Planing on going to Sea World, Disney Land, Universal Studios maybe go in the ocean for a swim and some other places. I was wondering how the weather might be in that month, too hot too cold perfect for walking around with shorts, tee, and sandals or what? I have gone before on 2008 on July weather was perfect, sunny no wind and not too hot. So any people that actually live there or have been there in that month (April) that have gone and done some of this things, if you could give me some info. Thank you.
