When to visit
San Andrés?

The Seven Colors in Flawless Light

Between January and April, the island operates at its absolute peak, bathed in steady, salt-laden sea breezes and nearly unbroken sunshine. The ocean behaves during these months. The swell along the eastern barrier reef subsides, flattening the lagoon into an immense, buoyant swimming pool where visibility through the water column seems endless.

This is the season to be out on the water from dawn until twilight. In the mornings, boats shuttle across the turquoise shallows to the palm-topped coral sand of Johnny Cay, where the reef breaks the surf into gentle white foam. Further south, you can wade waist-deep across a sandbar to Rocky Cay, the sea warm and clear as bathwater around your knees. On the main beachfront at Spratt Bight, the promenade fills with travelers sipping iced coconut water while the trade winds keep the air around 28 degrees, blunting the equator’s edge so that walking the sands remains a pleasure rather than an endurance test.

The trade-off is presence: everyone knows this is paradise. April represents the absolute summit of visitor numbers, particularly when Easter week packs the sands of Spratt Bight shoulder-to-shoulder with holidaymakers down from Bogotá and Medellín. Even so, the sheer perfection of the sea easily justifies the company. If you must choose, March offers the driest skies of the year with a fraction less clamor than the April peak.

The Heavy Air Before the Shift

May is the island’s hinge. The steady winter breezes begin to falter, and with their departure, humidity creeps inland. The air feels visibly thicker, sitting on bare skin like a warm damp towel by early afternoon, with temperatures feeling closer to the mid-thirties.

Rain showers arrive, but they are generally brief, tropical introductions to the wet season rather than day-long affairs. You can still easily spend full mornings out over the coral gardens, watching stingrays glide across the white sand floor, but the afternoon sky frequently brews tall, bruised-purple thunderheads over the interior ridges. It remains a workable shoulder month for travelers who prefer cheaper hammock space and quieter sandbars, provided you do not mind retreating beneath a thatched palm roof when the afternoon sky breaks.

Summer Squalls and Island Roots

June arrives with a heavy punch of rain. The downpours are sudden, loud, and intense, turning coastal paths into temporary waterways and regularly churning up the lagoon, which obscures the delicate visibility divers travel thousands of miles to see. Boat captains keep a wary eye on the horizon, and trips out to the farther sandbanks are frequently delayed or called off when squalls whistle through.

Yet June is also the month the island turns its attention inward, celebrating its heritage with the Green Moon Festival. While the beaches take a backseat to the weather, the streets and community grounds around the historic hilltop settlement of La Loma and the coast pulse with reggae, calypso, and soca. The air smells of slow-simmered fish rondon, coconut milk, and fried plantains. It is the single best moment on the calendar to grasp that San Andrés is not merely an offshore resort for the mainland, but a proud Afro-Caribbean enclave with a distinct Raizal identity and rhythm.

The Mid-Year Breeze and Passing Waves

July and August bring a partial reprieve from the torrential lows of early summer, accompanied by another influx of South American travelers on mid-year holidays. The days are hot, humid, and bright, punctuated by brief, furious downpours that usually clear within an hour to reveal steaming asphalt and brilliant sun.

The eastern shoreline around San Luis catches steady waves during this period, offering breezy respites from the heavy coastal humidity. Swimming and snorkeling are dependable again, though the water rarely matches the pristine, gin-clear glass of February or March. It is an energetic, slightly chaotic time—golf carts and rented scooters buzz relentlessly along the perimeter road, and the sound of dancehall spills out of open wooden houses alongside the sea.

The Drenched Low Season

From September through November, the southwestern Caribbean enters its wettest, most volatile stretch. October and November are genuinely waterlogged, receiving massive monthly rainfall that can stall island life for days at a time. The heat feels suffocating, hanging heavy between downpours, with apparent temperatures routinely settling into the mid-thirties.

When tropical depressions stall over the archipelago, outer reefs become violent walls of crashing white water. Port authorities regularly shut the cays to small passenger launches, leaving visitors stranded in the urban center of town with little to do under leaden skies. The shoreline at San Luis becomes strewn with drift and seagrass pushed ashore by angry swells. While airfares plunge and the streets clear of tourists, traveling here during these three months is a gamble where the weather routinely holds all the cards.

The Return of the Trade Winds

December marks the beginning of the island's redemption. Early in the month, the last retreating squalls of the rainy season still roll through, but by mid-December, the prevailing northeasterly trade winds reassert their dominion over the archipelago.

Almost overnight, the heavy dampness lifts. The breeze whisks away the stagnant heat, dropping the daytime feel back to a comfortable warmth, while the churned waters settle back into that crystalline sheet of turquoise. As the holiday season opens, the island transforms once more into a sun-soaked haven, readying itself for the radiant months to follow.
