The coldest months at Disneyland in Anaheim, California, are typically December and January. During this period, daytime high temperatures usually hover around 68°F to 70°F (20°C to 21°C), while nighttime lows can drop to a chilly 46°F to 48°F (8°C to 9°C). January is statistically the coolest month on average. These months also coincide with Southern California's "rainy season," so visitors should be prepared for occasional damp days. While these temperatures might seem mild to those from colder climates, the "desert chill" that sets in after sunset can feel quite sharp, especially when waiting for evening shows like World of Color or Fantasmic!. Experienced park-goers in 2026 recommend a layering strategy: light t-shirts for the sunny afternoons, followed by a medium-weight jacket or hoodie for the evenings. February is also relatively cool and often records the highest average rainfall of the year, so carrying a compact poncho or umbrella is a wise "pro-tip" for winter visits to the Happiest Place on Earth.
