Packing for a trip to the South Carolina coast in May requires a strategic approach to layering. Because daytime temperatures easily invite shorts and t-shirts, while evening coastal breezes can drop temperatures significantly, versatility is essential.

- Evening Outerwear: Pack at least two or three light jackets, cardigans, or windbreakers for dinners al fresco or evening strolls along the shore when the wind picks up.
- Sun Protection Gear: High-SPF sunscreen, polarized sunglasses, and a wide-brimmed hat are non-negotiable items given the strong ultraviolet rays present along the coastal corridor during late spring.
- Rain Contingency: A compact, wind-resistant travel umbrella or a lightweight rain jacket to handle brief, pop-up spring showers.
