Planning a visit to Anaheim in September means preparing for classic Southern California sunshine and warmth. This month sees average daytime temperatures comfortably ranging from the mid-80s to low 90s Fahrenheit (29-34°C), ensuring plenty of bright, sunny hours for exploring. While the days are often hot, evenings bring a welcome drop in temperature, typically settling into the mid-60s Fahrenheit (18-20°C) after sunset. Humidity levels are generally moderate, making the air feel pleasant, not overly oppressive. Precipitation is highly unlikely; September is firmly within the region's dry season, so you can expect clear skies almost daily. For practical outfit advice, think breathable fabrics and strategic layering. During the day, prioritize lightweight materials like cotton, linen, or moisture-wicking blends. Shorts, skirts, light dresses, and t-shirts are ideal for navigating theme parks or enjoying outdoor attractions. As the sun sets and the air cools, a light jacket, cardigan, or a denim jacket becomes essential to stay comfortable, especially if you're dining outdoors or waiting for nighttime spectaculars. Comfortable walking shoes are non-negotiable, given the extensive walking involved in most Anaheim itineraries. Don't forget a hat, sunglasses, and ample sunscreen to protect against the strong Southern California sun.
