The drier and slightly cooler season lasts approximately from February to April, when the average monthly temperature is about 25-26°C, and rainfall is minimal (about 1 mm per month).

When planning a trip to Saint Croix, remember that a warm tropical climate awaits you all year round. Average temperatures range from 25°C to 28°C, so the basis of your wardrobe should be light, breathable clothing made from natural fabrics such as cotton or linen. T-shirts, shorts, sundresses, light trousers, and skirts will be the ideal choice. Do not forget several swimsuits, as beach relaxation is an integral part of the visit. It is extremely important to take care of sun protection: be sure to take sunscreen with a high SPF, sunglasses, and a headpiece (a wide-brimmed hat or a cap). Light clothing will also be comfortable in the pleasant sea breeze.

Despite the fact that the total amount of precipitation in Saint Croix is small, statistics show that short-term tropical showers are possible in any month, especially from May to November, when the number of days with precipitation increases (for example, in September there can be up to 22). Therefore, it would be wise to pack a compact folding umbrella or a light raincoat that will not take up much space. Although the temperature remains high, a light cover-up or a long-sleeved shirt may come in handy for protection from the sun during the day or from the slight evening coolness by the water. Regarding footwear, give preference to comfortable sandals or flip-flops for the beach and daily walks, as well as light sneakers or loafers if you plan more active exploration of the island.
