7-day Sri Lanka itinerary for May to September: the east coast version

Sri Lanka has two monsoons that affect opposite coasts. The south-west monsoon, roughly May to September, brings rain, wind and heavy surf to the south and west coasts, including Mirissa, Galle and Bentota. The east coast, sheltered by the central hills, is at its driest and calmest in the same months.

That is why the May to September version of the 7-day Sri Lanka itinerary replaces the south coast with Trincomalee and the beaches just north of it at Uppuveli and Nilaveli. The Cultural Triangle, which sits between the two coasts, works well in both seasons and stays at the start of the route.

The monsoon does not mean constant rain on the south coast. Many days are partly sunny, with heavy showers rather than all-day downpours. The real problem for a short trip is the sea: red flags, strong currents and cancelled boat trips can remove exactly the beach days that make the classic route's final stretch worthwhile.

The east-coast version keeps the same first two days as the classic route and then turns east rather than south. It uses three bases rather than four, which also means fewer hotel changes and a more relaxed week overall.

The trade is the hill-country train: Ella and the Nine Arch Bridge are too far from Trincomalee to fit comfortably. Kandy gets two nights instead, and a day trip towards Nuwara Eliya's tea country is possible from there if you want a taste of the highlands.

Trincomalee has one of the finest natural harbours in the world, the Koneswaram temple on Swami Rock above the sea, and a string of beaches to the north. Uppuveli, just outside the town, has a relaxed stretch of guesthouses; Nilaveli, roughly 15 kilometres further north, has wider, quieter sand and the boat departure point for Pigeon Island.

Pigeon Island National Park, a short boat ride off Nilaveli, is one of the best snorkelling spots in Sri Lanka, with shallow coral and reef sharks commonly seen. It gets busy in peak weeks; go early, follow the rangers' instructions and never stand on the coral.

Mirissa's whale season ends around April, but boats from Trincomalee look for blue whales, sperm whales and dolphins roughly May to September, often in calmer water because the continental shelf drops away close to shore. Sightings are never guaranteed and vary from year to year.

A Trincomalee trip typically leaves early in the morning and lasts a few hours. As on the south coast, choose an operator that keeps its distance and does not chase the animals, and take seasickness precautions before boarding.

On a two-night east-coast stay, choose between whales and Pigeon Island rather than trying to do both on the single full day, since both involve early boat departures and the morning sea is calmest. Snorkelling suits families and non-swimmers in shallow water; whale trips suit those comfortable on open water for several hours.

Giving Kandy two nights in the May to September version is not a consolation prize. The extra day allows the Royal Botanic Gardens at Peradeniya, a tea estate visit, and a second chance at the Temple of the Sacred Tooth Relic in the morning, when it is calmer than at the evening puja.

July or August may also coincide with the Kandy Esala Perahera, the island's greatest Buddhist procession. Its dates shift each year with the lunar calendar and hotels fill quickly, so confirm the dates before fixing your week, and book early if they overlap.

Arugam Bay, on the south-east coast, is Sri Lanka's best-known surf spot and is also in season roughly May to September. It is further from the Cultural Triangle and from the airport than Trincomalee, though, and fitting it into seven days means long road days.

Surfers for whom the waves are the point of the trip should build a separate route around Arugam Bay. For a first-time visitor on a one-week trip, Trincomalee's calm water and shorter drives make it the better east-coast base.

Pasikudah, roughly two hours south of Trincomalee, is the other east-coast option: a long, shallow, reef-protected bay lined with resort hotels, well suited to families with small children. It sits roughly two and a half to three hours from Sigiriya, making it a straight swap for Trincomalee in this week.

The months from May to September are quieter than the December to April peak in the Cultural Triangle and hill country, and hotel rates can be lower as a result. The east coast is busy in July and August, which coincide with school holidays in many countries, so book beach hotels there early.

Lankan Stays & Trails routes one-week trips in these months east rather than south as standard, and our Grand Tour covers Trincomalee for travellers with more time. Travellers set on the south coast mid-year should read the rain plan in this series before deciding.
