Sri Lanka in March

Is March a good time to visit Sri Lanka?

Quick answer: Yes, especially if you want both coasts in one trip. On the long-term averages, every station in our 12-town table gets under 105 mm of rain in March: the south coast is still in season and the east coast around Trincomalee is drying out. Expect heat and some afternoon storms, and slightly fewer visitors than in February.

Sri Lanka Tourism places March and April in the first inter-monsoon, a "transitional period with afternoon thunderstorms. Warm and humid, ideal for visiting the cultural triangle and hill country" (Sri Lanka Tourism weather page). In practice, March keeps most of February's dry weather but adds heat. Coming earlier? Read Sri Lanka in February. Later? Read Sri Lanka in April.

What is the weather like in March, coast by coast?

Hot everywhere, and dry enough almost everywhere. The table uses the WMO 1991 to 2020 normals published by the US National Centers for Environmental Information (WMO normals, Sri Lanka stations). "Rain days" counts days with at least 1 mm.

Fahrenheit is converted from Celsius and rounded. A station is one point, so nearby beaches can differ.

What the table tells you:

• The wettest station in March is Colombo, at 102.7 mm. In January the wettest station in the same set gets more than 260 mm. That narrow spread is what makes March a "both coasts" month.
• The east is opening up. Trincomalee falls from 96.1 mm in February to 54.8 mm in March, over just 4 rain days. Batticaloa drops from 148.5 mm to 70.3 mm.
• The dry zone is very hot. Anuradhapura averages a high of 34.8 C (95 F). See Sigiriya and the ruins at opening time.
• The hills are pleasant. Nuwara Eliya averages 22.3 C (72 F) by day, warmer than in February.

Which coast should you choose in March?

You do not have to choose. A March trip can go south first, then cross to the east.

Sri Lanka Tourism's season chart lists May to September as the "best time to explore the dry zone: Trincomalee, Arugam Bay, and Jaffna" (Sri Lanka Tourism weather page). March is the shoulder before that, so the sea on the east can still be lively. The east coast vs south coast guide explains how the two coasts swap seasons.

What holidays fall in March 2027?

Four bank and public holidays, from four faiths. Expect busy roads and closed banks on each.

Source: the Central Bank's 2027 bank holiday list, read 17 October 2026. The festival calendar has the full year. Medin Poya and Good Friday create two long weekends (20 to 22 March and 26 to 28 March 2027), so expect busier roads and book transport for those days early.

Can you see whales in March?

Yes, and March is the one month when both whale coasts overlap. The International Whaling Commission's handbook lists blue whales off Mirissa from December to March and off Trincomalee from March to July, and sperm whale aggregations in March off Kalpitiya and Trincomalee (IWC handbook). The Sri Lanka Navy runs its southern cruises from November to April and moves to Trincomalee from May (Sri Lanka Navy). On 17 October 2026, whalewatching.navy.lk listed those seasons and did not state a pause; confirm sailings there.

How busy is Sri Lanka in March?

Quieter than the peak. SLTDA counted 183,979 tourist arrivals in March 2026, down from 229,298 in March 2025, a fall of 19.8%, and about a third below February 2026's 279,328 (SLTDA monthly arrivals 2026). SLTDA's table does not give a reason, so do not assume the same drop in 2027.

Some retreats also price March as a shoulder month. Barberyn Ayurveda Resorts listed a 10% room-rate reduction for 15 March to 14 April 2027 for guests staying at least a week on its treatment plan (read 17 October 2026). See Ayurveda in Sri Lanka for the full price table.

What should a March route look like?

For a full day-by-day plan, use the 3-week Sri Lanka itinerary. Hill country note: the Kandy to Ella line was not running through as of 17 October 2026. Go by road to Nanu Oya and take the Nanu Oya to Ella train. Apply for your ETA first with the Sri Lanka visa guide.

What should you pack for March?

• Light, breathable clothes and a wide hat; dry zone highs reach about 35 C (95 F).
• A light rain jacket or umbrella for afternoon storms.
• A warm layer for Nuwara Eliya nights, about 11 C (51 F), and for Adam's Peak, which is still in its December to May pilgrimage season (Sri Lanka Tourism, Sri Pada).
• Clothes that cover shoulders and knees for temples, especially on Poya and festival days.
• A refillable water bottle; heat is the main risk this month.
