Spring (April-May) or Fall (September-October). Visit Anaheim's own guidance recommends spring (60s-70s°F, no rain) and fall (high 70s-low 80s°F, back-to-school crowd drop) as the best balance of pleasant weather and lighter theme-park crowds compared to summer. October adds Knott's Scary Farm as a major seasonal draw
