What to Pack for September
Dress in layers — a mix of long sleeves, light sweaters, and a versatile jacket works best for changeable conditions. Temperatures drop significantly at night, so pack layers you can add or remove throughout the day. A waterproof jacket and shoes are non-negotiable — showers are frequent. Don't forget a wide-brimmed hat and high-SPF sunscreen — the sun is strong.
