Hiya Michael!
Thanks for coming to us at planDisney with your question. Oh boy, I'm so happy to hear that you'll be visiting the Happiest Place on Earth later this year! It'll be a great time to visit because the Southern California weather will still be warm and you'll be treated to some beautiful, late sunsets.
I'm afraid that Disney has not yet published the
Entertainment schedule this far in advance, so I'm unable to confirm whether or not
Fireworks will be occurring on those particular nights. Historically, Disneyland will have Fireworks nightly only during the summer peak season and then on Friday through Sunday nights during the off-season. Wondrous Journeys, the current nighttime spectacular at Disneyland Park, was designed so the projections are the main star and fireworks run only on select nights.
Over in Disney California Adventure,
World of Color - ONE is their nighttime spectacular and it is truly a sight to behold! It's the first show that combines music and scenes from classic Disney animation, Pixar animation, Star Wars, and the Avengers!
I wish I could offer more concrete answers, Michael. Only you can decide if fireworks are important enough to change your trip by a few days. I know you'll still have a fantastic trip to the Happiest Place on Earth. Be on the lookout for the beginning of the Halloween Season at the
Disneyland Resort around that time as well!
Good luck on your planning and feel free to come by and visit us again here at planDisney. We're here to help!
Have a Magical Day!
