Its been pretty chilly lately. And windy. For me, Id say not exactly shorts weather. You might get by on a tshirt, but definately have a sweatshirt or jacket on hand. Nightime is definately cold.

The past few days has been cold in the mornings, warming up, and then cooling off again at night.
Yesterday was 34 degrees when I went to work at 7 am in Irvine, warmed up to about 73. At about 9 pm it cooled down to 53. Anaheim is basically the same, maybe no more than 5 degrees warmer during the day, but the morning and evening temps would be about the same.
This morning it was 36 degrees when I came into work.
I heard it's supposed to rain this Sunday and then again on Wednesday.
One could probably wear shorts all day, as there is a lot of walking to do. Bring a sweatshirt with a hood for night. Tie it around your waist or rent a locker or keep it in the car and flip coins to see who has to go back to the car to get the extra clothes.
Depends on your tollerances. We were there last week when it was windy and in the mid 60's. I was wore shorts for our entire stay. During the day a t-shirt. In the evenings I would put on, over my t-shirt, the Nightmare Before Christmas jersey I bought on our first day and I was perfectly comfortable. There were many more people around dressed as if it were about to snow which seemed kind of extreme to me.
You can think I'm wrong, but that's no reason to quit thinking.
