Sigh....we’re supposed to go on a 9 day trip to California the first week of June including DL for 2 days. Even if the park is open by then, my husband isn’t sure he wants to go then, he says we should probably push it further out. He is talking spring break in early April next year.

I would love to keep it in this year and maybe go on fall break, early October. I haven’t cancelled June yet, I don’t want to til I absolutely have to, I’m in denial, lol. Anyone on this thread been to California in October or April? What’s our best bet weather wise? We’re also spending 2 days driving up the coastal highway from LA to San Francisco.
Lifetime CA resident here - I've lived in both norcal (where I am now) and socal. The weather would likely be very nice in both October and April, but I think warmer, on average, in October, especially early October. We just went to
Disneyland in early October this past fall. I'm a teacher, so we went over my long 4 day (fall break" weekend. The weather was very nice, but it definitely is warm. Of course, we've had 85 degree weather at Disneyland in November, March, and July...so who knows? Another thing to keep in mind is that Gay Days is in early October. We were there the 4-6, which was the Gay Days weekend. It was definitely more crowded because of that event, though not unmanageable. Just something to keep in mind. My gut feeling is that April is more crowded, though, especially if you're there during the week before or after Easter, which is when most CA schools have their spring breaks. If October break coincides with Columbus weekend, you are going to see a lot more crowds over that weekend. Weeklong fall school breaks aren't super common in CA, but having that Monday off is, so a lot of people spend 3 day weekends at Disneyland. We loved our October trip, and would go at that time again in the future, given the opportunity.
October is also the Halloween party (Oogie Boogie bash at DCA again this coming fall), which is very fun. Even without the party, you get the fun treats, decor, etc of fall/Halloween time. If your family likes that, it could be really fun. Also, if you've never done Disney in the fall (not sure if you have), it's something that should definitely be enjoyed at some point!
P.S. I'm the same way with not canceling our June trip yet, though with a lot of schools in CA making tentative plans to not reopen this year, I'm not super optimistic that I'll want to go even if the parks are open by then. Mostly I'm just trying not to think about it. My current gut feeling is that our June trip may move to Thanksgiving week.
