What is the weather like in December in Anaheim?
When packing, keep in mind that the weather in Anaheim in early December is typically cool during the day and cold at night. The average high is 66 degrees and the average low is 48 degrees. December is typically the rainy season so keep in mind a rain jacket with a hood or umbrellas when packing. Hotel and Convention Centers are also cool, and thus, ASHP highly recommends that you bring a sweater and layers with you when attending sessions.
