No. VII · May · mmxxviArugam Bay

The shift on the east coast happens without announcement. In late April the sea between Batticaloa and Trincomalee is still running at the wrong angle, grey and unsettled, carrying the last of the north-east swell. By the second week of May the surface changes. At Arugam Bay, sixty kilometres south, the main point begins to work. The first sets of the season are perhaps two feet, but the shape is already clean. Suresh, who has watched this break from the same position on the rocks at the tip of the point for twenty-two years, says the water knows before the calendar does.

The Arugam Bay surf season runs, in a reliable year, from the second week of May through the end of October. The main point is a right-hander that peels for a hundred and fifty metres on a good swell — consistent and forgiving at the start of the season, faster and more demanding as the south picks up through June and July. There are four other breaks within a twenty-minute tuk-tuk ride: Pottuvil Point and Whiskey Point are empty on days when the main point draws a crowd. In the first weeks, when the instruction windows are long and the water is at its warmest, the quieter breaks are where we send guests who are learning.

North of Arugam Bay, Trincomalee is a different proposition. The harbour — one of the deepest natural anchorages in the world — frames a set of beaches that run from Uppuveli south to Marble Beach, and the water clarity in May, before the high-season traffic increases, is exceptional. The boats that go out to Pigeon Island for the reef are small; a group of six feels like a private departure. Whale shark sightings on this coast run roughly March to October, with density highest in the warm months of May and June, before the boats multiply.

Further south, at Pasikuda, the coral shelf that runs parallel to the shore creates a lagoon of unusual stillness. The water is shallow for a long way out, the bay faces north-east, and the swell that the surfers at Arugam Bay are following does not reach here. Guests who had assumed that Sri Lanka's coast was too exposed come to Pasikuda and understand what they had been looking at on a map without reading correctly. The distinction between the east-coast bays and the south-coast beaches is real, and worth the extra hours of travel.

The practical consideration, for a journey that wants to use the east coast seriously, is sequence. The east coast dry season and the west coast dry season run against each other: when Galle and Mirissa are in monsoon, from May through September, the east is at its best. A journey that begins in the south in February and moves east in May is working with the island's geography rather than against it. The coast journey we build around Arugam Bay, Trincomalee, and Pasikuda is not a contingency plan for a washed-out itinerary. It is a second Sri Lanka.

When we call Suresh at the start of May to ask about conditions, he gives the same answer he has given every year. The main point is ready. Come. We have not found a more reliable signal than that call.
