Castries in December
Great time to visit
December marks the return of Saint Lucia's perfect weather window. Christmas crowds and holiday pricing kick in, but the reliable sunshine and comfortable temperatures justify the expense.
Weather
December ushers in peak dry season with gorgeous, comfortable weather returning to Castries. Trade winds blow steadily, humidity drops significantly, and rain becomes rare. Evenings can actually feel cool enough for light layers around the harbor.

All Months
December through May gives you the sweet spot — dry weather, steady trade winds, and temperatures in the low 80s. This is peak season, so expect crowds at popular spots and higher prices across the board. But the weather rarely disappoints. June through November brings more rain and humidity, plus the looming threat of hurricanes. The upside? Hotel rates drop significantly, and you'll have beaches mostly to yourself. Rain usually comes in quick afternoon bursts rather than all-day downpours. Carnival season in July gets the city buzzing with street parties and calypso competitions. Just be ready for everything to shut down during the actual carnival days. Christmas and New Year's bring the biggest crowds and highest prices — book months ahead if you're coming then.
