What to Pack for December
Light, breathable fabrics like cotton and linen are essential. Opt for loose-fitting clothing in light colors to stay cool. Temperatures drop significantly at night, so pack layers you can add or remove throughout the day. Don't forget a wide-brimmed hat and high-SPF sunscreen — the sun is strong.
