Is March Right for You?

Weigh the advantages and considerations before booking

Advantages
  • + Trade-winds blow steady at 15-20 knots. The Grenadines become a sailor's playground. Flat-water reaches link Bequia and Mustique. You can broad-reach all afternoon.
  • + Humpback whales still migrate north now. Catch the early mail boat from Kingstown. Half the time you'll spot blows off Union Island's leeward coast.
  • + Room rates drop 25-30% after Valentine's week. Beachfront cottages on Lower Bay suddenly answer. February sold out; March picks up.
  • + March nights hit 20°C (68°F). Sleep with windows wide open. Skip the AC surcharge hotels quietly add in summer.
Considerations
  • The Sahara dust layer drifts in mid-month. Sky glazes beige. Allergies spike. Sensitive travelers, pack antihistamines.
  • Catamaran day-trips sell out fast. Wait until you arrive and you'll watch boats leave for Tobago Cays without you.
  • Some beach bars on smaller cays close after Carnival. Annual maintenance shutters shacks. Call ahead if you crave that particular rum punch.

Best Activities in March

Top things to do during your visit

Grenadines Sail-Loop Day Trips

March trades give you a perfect beam-reach from Bequia to Mustique. No pounding through chop. The 19 km (12 mile) stretch takes 90 minutes under sail. You'll anchor in Britannia Bay before day-trippers arrive from St Vincent. Water temperature sits at 26°C (79°F). Snorkel the Mustique reef without a rashie.

Booking Tip: Secure your berth two weeks ahead. Boats carry 12 passengers max. They fill fast with yachties' visiting friends. Licensed operators display a red-on-yellow SVGSA sticker near the helm. Check before you pay.
La Soufrière Cross-Island Hike

Morning cloud keeps the crater rim at 24°C (75°F). March showers have packed the trail. You won't eat volcanic dust. The 9 km (5.6 mile) Vermont Nature Trail ascent starts cool at 07:00. You're back in Richmond Vale before 11 am sun turns serious.

Booking Tip: Guides are mandatory above 300 m (985 ft). Hire at the trailhead. Book through your guesthouse the night before. Transport gets sorted.
Tobago Cays Turtle Snorkel

March water clarity hits 30 m (98 ft) visibility. The reef wakes after winter. Hawksbills cruise seagrass beds by 09:30. Anchored charter cats haven't spooked them yet. Current between Petit Rameau and Petit Bateau runs mellow. Good for drift-snorkeling with a GoPro.

Booking Tip: Day-tours leave Union at 08:30. Pick boats that stock reef-safe sunscreen. Parks rangers fine visitors who slick up with oxybenzone.
Kingstown Market Food Walk

Saturday morning is peak. Breadfruit roasts over charcoal outside. Nutmeg scent drifts from spice stalls. Vendors shout prices in Vincy patios. March brings the first dasheen harvest. You'll see fresh tarro fritters, crispy outside, purple-sweet inside, fried while you wait.

Booking Tip: Arrive before 08:00. Mountain produce is still cool. Bring small Eastern Caribbean bills. Most stalls skip cards.
Bequia Whale Heritage Site Tour

The humpback corridor runs 3 km (1.9 miles) offshore. Local whalers-turned-guides know the exact contour. Mothers rest there with calves. March 15-April 10 is the sweet spot. Calves surface more often. Adults breach heading north. Tours leave Paget Farm at dawn. Sea is glassy. Blow spouts catch the low sun.

Booking Tip: Only four boats hold the heritage-site permit. Book the evening before. Captains read the overnight weather fax for swell height.

Essential Tips

Insider knowledge and common pitfalls to avoid

Insider Knowledge
Catch the 06:30 inter-island schooner from Kingstown. Locals board first. They claim the shaded aft benches. Tourists arriving at 06:15 end up sun-baked on the bow for two hours. Order 'blackfish' at Lower Bay shacks. It sounds exotic. It's simply local tuna, grilled within an hour of catch. Served with a squeeze of calamansi lime. If Sahara dust turns thick, swap beach time. Head to St Vincent Botanical Gardens. The 1785 breadfruit trees create a green filter. Parrots chirp louder when dust muffles reef noise. Wi-Fi is sold by the hour on Union. Buy a 5-hour code at the airport gift shop. No signal reaches the Cays once you sail out.
Avoid These Mistakes
Don't assume US dollars work everywhere. Carry Eastern Caribbean dollars. Otherwise you'll get a poor 2.50 rate instead of 2.70. Avoid scheduling same-day international connections after island ferries. March winds delay boats more than the schedule admits. Don't skip Bequia's leeward side on windy days. Friendship Bay can be glass-calm. Admiralty Bay chops white at the same moment.
