Best Time To Visit Saint Lucia: The Complete Guide

Much like Greek mythology’s Helen of Troy, Saint Lucia is breathtakingly beautiful. In both past and present, the island has stolen the hearts of many with merely a first glance. Green, pristine, and bountiful, the island has a history punctuated by a tug of war between the French and British, each vying for commandership of the island’s chief Fort, located at Morne Fortune. Whoever controlled this Fort controlled the island.

Shoulder season

In between the high and low season, travel in the shoulder season has its perks. On the upside, if you decide to travel during the shoulder season, which includes the months of Mid-April to June, chances are you’re going to get the best of both worlds. You’ll find it relatively easy to secure airfare and accommodation as you’ll be traveling at a time with moderate amounts of activity on the island, which also means you won’t have to battle with the crowds! The weather is still great and you will find top accommodation at lower rates.

Low season

Low Season in Saint Lucia often corresponds with the wet season, which spans from June to November. Lots of people take advantage of travel in the low season because of the associated discounts and fare cuts. Some resorts offer reduced rates during the low season, which means you can probably book more nights for your trip! The low season is ideal for last minute travel or travelling on a budget.

In Castries, you can check out the Vendor’s Arcade, the Castries Market, or La Place Carenage, all of which are relatively easy to find.
