So here on November 1st, I'm thinking about 80% of the Halloween decorations have been removed from Disneyland (virtually overnight). Space Mountain is closed to remove the Ghost Galaxy overlay. Yes, the Disneyland seasons are changing as Halloween goes out and Christmas comes up. By the end of this week, a sixty foot fully decorated Christmas tree will appear in the plaza on Main Street.
But now not only does the Disneyland holiday season change, this is really the point where you really begin to see the weather change as well. Not that Southern California has pronounced weather changes, but you very definitely can feel a change in the Disney weather. So now we have moved from months of dry weather into at least chances of days of rain or showers. From warm summer nights, we move to make sure you have a sweatshirt or jacket with you as once nightfall comes, the temperature drops in a hurry. The change of seasons also makes the sometimes ridiculously long lines for water rides Splash Mountain and Grizzly River Run that appear in summer actually not so bad (or if the weather is cold enough, no line at all). The 75 to 95 degree days of summer have now given way to temperatures that more are likely in the range of the low 60s to high 70s. Not that you can't have a warm 80 or 90 degree day or two in November and December but that is more the exception rather than the rule.
There is a lot to like about warm summer days (and nights) in Disneyland but the crowds that warm weather attracts from locals to days were warm becomes insufferably hot are not on the "like" list for me and Mrs. DisneylandTraveler. A nice 70 degree day with a night time drop to the high 50s or low 60s suits us just fine. We can wear pants (as opposed to shorts). We can put on light jackets and sweatshirts. We can even endure a little (or even a lot) or rain.
Yes, the weather is cooling down as the days grow shorter but now, entering the Christmas season, Disneyland will just keep getting better and better.
