Things to Do in Castries in March
March weather, activities, events & insider tips
March Weather in Castries
Is March Right for You?
Advantages
- Shoulder season pricing means you'll find accommodation rates 20-30% lower than peak winter months, with far fewer cruise ship crowds at Castries Market and Pointe Seraphine - you can actually browse the vendor stalls without being shoulder-to-shoulder with other tourists
- The sea conditions are genuinely excellent for water activities - visibility for snorkeling typically reaches 20-25 m (65-80 ft) around Anse Chastanet and the marine reserve, and the Caribbean side stays calm enough for beginners most days
- March sits right at the tail end of the dry season, so you're getting mostly sunny days with brief afternoon showers rather than the prolonged downpours of summer - those 10 rainy days usually mean 20-30 minute bursts, not all-day washouts
- The northeast trade winds are still blowing consistently at 15-20 km/h (9-12 mph), which keeps things comfortable despite the humidity and makes this one of the last reliable months for sailing trips along the west coast before the winds die down in summer
Considerations
- That 70% humidity is no joke - it's the kind that makes your clothes feel damp within minutes of leaving air conditioning, and if you're not used to tropical climates, you'll be sweating through shirts by mid-morning even when standing still
- March falls awkwardly between Carnival (usually February) and Jazz Festival (typically May), so you're missing the island's two biggest cultural events - the local vibe is noticeably quieter without these celebrations
- Some hiking trails, particularly the upper sections of Tet Paul Nature Trail and routes through the rainforest interior, can be muddy and slippery from those afternoon showers - the red clay soil stays slick for hours after rain stops
Best Activities in March
Pitons hiking and photography tours
March offers the sweet spot for tackling Gros Piton - early morning temperatures around 23°C (73°F) make the 2-3 hour climb manageable before the midday heat kicks in, and the clearer dry-season air means you'll actually see Martinique from the summit on most days. The trail can get muddy near the top from afternoon showers, but mornings are typically dry. Book sunrise slots if you can handle a 5am start - the light hitting Petit Piton from that angle is spectacular, and you'll have the trail largely to yourself.
West coast catamaran sailing trips
Those consistent northeast trade winds make March one of the last excellent months for sailing before the summer doldrums. Half-day and full-day catamaran trips along the west coast from Rodney Bay to Soufriere offer calm seas, strong enough breeze to actually sail rather than motor, and excellent snorkeling stops at Anse Cochon and the marine reserve. The water temperature sits around 27°C (81°F) - warm enough to stay in for an hour without a wetsuit. Most tours include rum punch and lunch, departing around 9am and returning by 4pm.
Castries Market and street food exploration
Saturday mornings at Castries Market are when the produce is freshest and the energy peaks - locals shop early to beat the heat, arriving by 7am when vendors are setting up. March brings seasonal fruits like golden apples and local avocados the size of your head. The humidity makes hot food incredibly appealing despite the temperature - you'll find vendors selling accra (saltfish fritters), bouillon (one-pot stew), and fresh coconut water for 10-15 Eastern Caribbean dollars. The covered market stays relatively cool, and by 11am when it gets uncomfortable, you're done anyway.
Sulphur Springs and botanical garden visits
March's variable weather actually works in your favor for the drive-in volcano and botanical gardens - those brief afternoon showers cool things down and create dramatic mist effects around the sulphur vents. The Sulphur Springs mud baths sit at a constant 40°C (104°F) regardless of weather, and soaking in volcanic mud while warm rain falls is oddly satisfying. Diamond Falls Botanical Gardens looks particularly lush after the dry season rains start picking up in March. Plan these for early afternoon when the morning activities are done and you don't mind getting wet anyway.
Rainforest canopy and waterfall hikes
The interior rainforest trails through Enbas Saut and to waterfalls like Toraille and Enbas Saut Falls are muddy in March but manageable with proper footwear - and the recent rains mean the waterfalls are actually flowing strong, unlike the trickle you sometimes get in peak dry season. The forest canopy keeps you shaded and the temperature drops 3-4°C (5-7°F) under the trees. Morning hikes work best before afternoon showers arrive. The humidity makes the forest feel properly tropical, with mist rising from the vegetation.
Snorkeling at marine reserves and reefs
March delivers some of the year's best underwater visibility at 20-25 m (65-80 ft) around Anse Chastanet Marine Reserve and the reefs near Anse Cochon. The sea temperature around 27°C (81°F) means you can snorkel for an hour comfortably without a wetsuit, and the calm Caribbean side conditions make this accessible for beginners. The marine life is active - you'll regularly spot sea turtles, eagle rays, and schools of sergeant majors. Shore entry sites like Anse Chastanet let you go at your own pace, while boat trips reach the better reef systems offshore.
March Events & Festivals
Saint Lucia Independence Day
February 22nd is the actual date, but celebrations and local pride continue into early March with community events, cultural performances, and special menus at restaurants featuring traditional Saint Lucian dishes. You might catch lingering decorations in blue, black, gold and white around Castries, and some hotels run special cultural evenings with local music and dance. It's not a major tourist event but gives you a sense of national identity that's otherwise harder to access.
