What to Wear in Anaheim in September
September in Anaheim is warm, sunny, and almost entirely dry — summer at its most settled, with highs near 85°F and lows around 66°F. With only about 1 rainy day for the entire month, it's peak Southern California outdoor weather. Light summer clothes and a layer for air-conditioned theme parks are all you need.
September in Anaheim is the continuation of summer by another name — the Pacific High that suppresses coastal moisture holds firm through mid-month, inland temperatures stay comfortably warm, and the tourist machinery of the Disneyland Resort runs at a pace that's marginally more manageable than July or August without the crushing school-holiday crowds. The Anaheim Packing District's outdoor spaces, Katella Avenue's restaurant corridor, and the Angel Stadium crowds for the baseball season's final weeks all operate in reliably warm, dry conditions that make outdoor time genuinely pleasant. Santa Ana wind events can begin to develop in late September, occasionally pushing temperatures into the upper 80s or low 90s and dropping humidity to single digits. The wardrobe reality of September Anaheim is almost laughably simple: it barely rains, it's consistently warm, and the only variable worth planning around is the gap between outdoor heat and indoor chill. Disneyland, the convention center, and most restaurants maintain aggressive air conditioning that can make a thin sundress feel genuinely cold within twenty minutes of entering. The solution is a light packable layer — a denim jacket, light cardigan, or zip-up hoodie — carried in a bag or around your waist for the indoor transitions. Evening temperatures settle around 66°F, which feels pleasant and slightly cool after a warm afternoon, and is perfectly comfortable in a light layer over a summer outfit.
