Visiting Castries in December

December weather

December feels warm and humid in Castries, with highs around 27°C and little change after dark. Rain falls on 14 days, but showers are often brief; you'll still get plenty of sunshine between them. It's a good month for a walk around the Castries Market, a visit to Derek Walcott Square, or an afternoon at Vigie Beach.

Rain can make forest paths slick, so save a hike in the nearby hills for a drier spell. Compared with November, December is much less rainy, though January is a little drier still.

Christmas in Castries

The Festival of Lights and Renewal brings Christmas celebrations to Castries around Saint Lucy's Day in December. Look for lantern displays and local festivities in town. Christmas itself is a family holiday, so some shops and services may close or run shorter hours.

If you hate crowds, go to the market on an ordinary weekday rather than close to Christmas. The city gets busier as the holiday period approaches.

Crowds and practical tips

December marks the start of Saint Lucia's busy winter travel season. The weeks around Christmas and New Year tend to draw more visitors, and accommodation can cost more than in quieter months. Early December is often a calmer choice; February and March are the island's best-rated months overall.

Travelling with kids? Vigie Beach is close to Castries, so you can enjoy a swim without a long trip across the island. For a practical stop in town, visit the Castries Market in the morning, when vendors are selling local produce and dishes. Try green fig and saltfish, Saint Lucia's national dish, before heading back to the waterfront.
