Hello Nicole!
Thanks so much for stopping by the Disney Parks Moms Panel! I hope you are having a magical week!
Disneyland Resort has a great
When to Visit guide that helps plan when the parks are busiest, average temperatures, special events and estimated park hours. Generally speaking, the time you are planning on visiting has fewer crowds because schools are going back in session. It’s hard to estimate the crowds this early, but I prefer to go mid-week, usually Tuesday and Wednesday are the days I like to visit.
Also, there is a non-Disney affiliated site called TouringPlans that has a great app for Disneyland Resort wait times, crowds, etc. I believe the app itself is free, but you then have to purchase a 1 week, 1 month or 1 year subscriptions.
I hope this helps and let me know if you have any other questions as your plan your visit!
See you real soon!
