What to Pack for September
Summer clothing like shorts, t-shirts, and sundresses will be comfortable. Bring a light cardigan for air-conditioned spaces. Temperatures drop significantly at night, so pack layers you can add or remove throughout the day. Pack a compact umbrella or light rain jacket for occasional showers. Don't forget a wide-brimmed hat and high-SPF sunscreen — the sun is strong.
