Sri Lanka's beach weather is warm and humid, so it's crucial to pack the right clothing. Opt for lightweight and breathable options like cotton t-shirts, shorts, sundresses, and swimsuits. These will keep you cool and comfortable as you bask in the sun. Remember to bring a wide-brimmed hat and sunglasses to shield yourself from the scorching sun. To complete your beach attire, don't forget to pack flip-flops or comfortable sandals, as the sandy terrain is perfect for casual footwear. Additionally, a light shawl or cover-up can come in handy when you want to take a break from the sun or visit beachfront restaurants without changing out of your beachwear.
