During the summer months, be sure to pack light clothing. Bring shorts, T-shirts and a thin jacket. During the winter months, be ready to dress in layers. Pack jeans, T-shirts or long-sleeved shirts for daytime and a sweatshirt and heavy jacket for mornings and evenings.

When packing for Disneyland (California), the most critical item is comfortable, broken-in walking shoes. Most visitors walk 10–15 miles a day, so skip brand-new sneakers or flip-flops. Southern California weather is famously variable; mornings and evenings are often cool (60s°F), while midday can be hot and sunny (80s°F or higher). The "Disney uniform" should include layers: a moisture-wicking T-shirt, comfortable shorts or leggings, and a lightweight hoodie or denim jacket for the evening. If you're visiting during the winter months (December–February), a water-resistant rain jacket or poncho is essential, as rain showers are more frequent. Additionally, sun protection is a must—a wide-brimmed hat, polarized sunglasses, and a small tube of sunscreen will prevent the "Disney burn" from standing in outdoor queues. If you plan to ride Grizzly River Run in Disney California Adventure, consider bringing a small, quick-dry towel or a change of socks, as you will likely get soaked. Lastly, while costumes for guests over age 14 are generally prohibited, "Disneybound" (outfits inspired by character colors) is a popular and fun way to dress up.
