Sri Lanka in July and August

Is July or August a good time to visit Sri Lanka?

Quick answer: Yes, if you base your trip on the east coast, the north or the Cultural Triangle. July and August fall in the south-west monsoon, so Arugam Bay, Trincomalee and Jaffna are dry and hot while Galle and the hills stay showery. August is also the usual month for the Kandy Esala Perahera, and Trincomalee runs whale cruises.

This page covers both months because the weather pattern is almost the same. If your dates start in June, see Sri Lanka in June. If they run into the autumn, read the best time to visit guide for September onwards.

What is the weather like in July and August?

Sri Lanka Tourism's weather page describes May to September as the south-west monsoon: "Heavy rainfall on the southwest coast and hills. Best time to explore the dry zone: Trincomalee, Arugam Bay, and Jaffna." The 30-year averages show how big the gap is.

Source: WMO 1991 to 2020 normals, NOAA archive. "Days" are days with at least 1 mm of rain. Highs are average daily maximums. These are long-term averages, not a forecast.

What this tells you: Galle gets about 10 times the July rain of Pottuvil. The dry zone is also the hot zone, with highs of 33 to 35 C, so plan sightseeing for the early morning. August is slightly wetter than July in the north and east, but still dry by Sri Lankan standards.

Where should you go in July and August?

Sri Lanka Tourism names Arugam Bay as a dry-zone place for this season. Our Arugam Bay guide gives Sri Lanka Tourism's April to October surf season. The east coast vs south coast guide explains why the two coasts swap seasons.

When is the Kandy Esala Perahera?

The Temple of the Sacred Tooth Relic says the Dalada Perahera is held "in the month of Esala (July) annually", but the dates move with the lunar calendar. For 2026 its official schedule ran in August:

Source: Sri Dalada Maligawa, Kandy Esala Perahera, read 20 October 2026.

For 2027: the temple had not published dates on 20 October 2026. The procession is tied to the Esala and Nikini lunar months, so expect late July or August, and do not book a Kandy hotel for the Perahera until the temple's schedule is out. The final Randoli night is the busiest. Our festival calendar lists the other big events.

When are the Poya days in July and August 2027?

The 2027 public holiday gazette lists:

Poya days are Buddhist holy days, and temples fill with worshippers. Visit respectfully, dressed to cover shoulders and knees. The weekend of 14 to 16 August 2027 has two holidays in a row, so expect busy roads and full trains.

Can you see whales in July and August?

Yes, from Trincomalee. The Sri Lanka Navy lists whale cruises from Trincomalee from May to October, every Saturday and Sunday at 7.00 am from the Nicholson Cove pier at the Naval Dockyard (Sri Lanka Navy schedules).

Each cruise lasts 5 hours. The Navy's south coast cruises run in the November to April season, so they do not fit a July or August trip. Stay in Nilaveli or Trincomalee for the early start.

What does a good July or August route look like?

A 10-day loop that follows the dry weather:

Want more detail? The east coast itinerary and the cultural triangle itinerary both fit these months.

Do you need a visa?

Yes. Everyone needs an Electronic Travel Authorization (ETA) before arrival. The official ETA site lists 40 countries, including the UK, India, Germany, Japan and the United States, whose citizens get a free 30-day tourist ETA. Our Sri Lanka visa guide has the full list and the fees for everyone else.

What should you pack for July and August?

• Light, loose cotton for 33 to 35 C heat in the dry zone, plus a hat and high-factor sun cream.
• Clothes that cover shoulders and knees for temples and the Perahera.
• A light rain jacket for Kandy, Nuwara Eliya and the south-west.
• A warm layer for Nuwara Eliya, where highs are about 19 C.
• Snorkel gear if you plan to visit Pigeon Island off Nilaveli.
