Sri Lanka Weather in March: A Glimpse of the Island’s Tropical Climate

Sri Lanka in March: Quick Overview {#overview}

March marks the tail end of the northeast monsoon in the north and east, while the southwest and west coasts remain firmly in their dry season. The result is a rare window where almost every part of Sri Lanka enjoys good weather simultaneously — a condition that's hard to replicate in any other month.

Temperature by Region in March {#temperature}

Sri Lanka's varied topography means temperatures differ significantly between coastal, highland, and inland areas.

West & South Coast (Colombo, Galle, Mirissa, Bentota, Hikkaduwa)

The west and south coasts are in peak season during March. Expect warm, sunny days with:

• Daytime highs: 30°C – 33°C (86°F – 91°F)
• Nighttime lows: 24°C – 26°C (75°F – 79°F)
• Humidity: High, but tempered by coastal breezes
• Rainfall: Minimal — typically 5 to 7 rain days in the month

Beaches like Mirissa, Unawatuna, and Hikkaduwa are at their best: calm seas, clear water, and long sunny days.

Hill Country (Kandy, Ella, Nuwara Eliya)

The central highlands offer a refreshing escape from coastal heat:

• Kandy: Highs of 29°C – 31°C, lows around 19°C – 20°C
• Ella: Pleasant mid-20s during the day, cool evenings
• Nuwara Eliya: Highs around 22°C – 24°C, with cool nights dropping to 14°C – 18°C

March is one of the driest months in the hill country, making it perfect for tea plantation visits and scenic hikes without the usual mist.

Cultural Triangle (Sigiriya, Dambulla, Anuradhapura, Polonnaruwa)

The interior is hot and mostly dry in March:

• Daytime highs: 33°C – 36°C (91°F – 97°F)
• Rainfall: Very low — one of the driest periods of the year
• Best time: Early morning visits to ancient sites to beat the midday heat

North (Jaffna, Kilinochchi)

The north is hot with minimal rainfall:

• Daytime highs: 31°C – 34°C (88°F – 93°F)
• Rainfall: Very low (~27mm average), as the northeast monsoon winds down
• Excellent for exploring Jaffna's colonial heritage and island-hopping

East Coast (Trincomalee, Batticaloa, Arugam Bay)

The east coast transitions from the monsoon toward dry season during March:

• Daytime highs: 29°C – 32°C (84°F – 90°F)
• Rainfall: Reducing through the month — late March sees drier conditions
• Trincomalee's beaches begin opening up; Arugam Bay starts coming alive

Rainfall & Sunshine Hours in March {#rainfall}

March is one of Sri Lanka's drier inter-monsoon months, with the country averaging around 80mm of rainfall for the month — compared to 300mm+ during the peak southwest monsoon in May and June.

Key rainfall figures by destination:

Any rain that does occur is typically brief afternoon or evening showers that clear quickly — they rarely disrupt a full day of sightseeing or beach activities.

Sunshine: Most coastal and inland destinations enjoy 7–9 hours of sunshine daily, making March one of the sunniest months of the year across much of the island.

Best Places to Visit in Sri Lanka in March {#places}

1. Mirissa & the South Coast

March is arguably the best month to visit Mirissa. The sea is calm, the sand is golden, and the whale-watching season is at its peak. Blue whales and sperm whales can be spotted just offshore — one of the most remarkable wildlife experiences in Asia.

2. Sigiriya & the Cultural Triangle

The ancient rock fortress of Sigiriya is spectacular in March. Cooler mornings make the climb comfortable, and the surrounding plains are bathed in golden light. Combine with visits to:

• Dambulla Cave Temples — Sri Lanka's largest cave temple complex
• Anuradhapura — an ancient capital with UNESCO-listed ruins
• Polonnaruwa — hire a bicycle to explore the medieval city ruins

3. Kandy

Sri Lanka's cultural capital is beautiful in March, with low rainfall and comfortable temperatures. Must-sees include the Temple of the Tooth Relic, Kandy Lake, and the Royal Botanical Gardens in nearby Peradeniya.

4. Ella & the Hill Country

March is a dream for hikers and nature lovers heading to Ella. The trails to Little Adam's Peak and Ella Rock are clear, the waterfalls are flowing, and the tea plantations are lush. The famous Nine Arch Bridge is best photographed in the morning light.

5. Trincomalee (Late March)

By late March, Trincomalee's beaches — including the beautiful Nilaveli and Uppuveli — are transitioning into their dry season. Snorkelling, diving, and dolphin watching begin to pick up. An increasingly popular alternative to the crowded south coast.

6. Jaffna

Sri Lanka's northernmost city is hot but largely unexplored by mainstream tourism. March is ideal for its colonial Dutch forts, vast Nainativu Island temples, and freshwater lagoon scenery. A rewarding off-the-beaten-path destination.

Things to Do in March {#activities}

? Whale Watching

The waters off Mirissa and Trincomalee are alive with blue and sperm whales in March. Mirissa is the most accessible departure point from the south — boats typically leave at 6:30am.

? Surfing

Hikkaduwa on the west coast offers consistent surf in March. The southwest swell produces good rideable waves for beginner and intermediate surfers.

? Wildlife Safaris

Yala National Park is excellent in March before the southwest monsoon. Leopard sightings are common; elephant herds are also frequently spotted at waterholes. Udawalawe is another top option for elephant sightings year-round.

? Hiking Adam's Peak

March is the tail end of the Adam's Peak pilgrimage season (December–May). Climbing overnight to watch the sunrise from Sri Pada (2,243m) is a deeply memorable experience, combining physical challenge with spiritual atmosphere.

? Snorkelling & Diving

The calm seas of March make Hikkaduwa Marine National Park, Pigeon Island (Trincomalee), and the waters off Unawatuna ideal for snorkelling and diving. Coral, turtles, and reef fish are abundant.

? Tea Plantation Tours

The hill country's dry March weather makes it perfect for guided walks through Nuwara Eliya tea estates. Factory tours explain the full production process from leaf to cup.

Medin Poya (Full Moon Poya Day)
One of Sri Lanka's most important Buddhist observances, Medin Poya commemorates the Buddha's first visit to his father's kingdom after attaining enlightenment. Expect temple ceremonies, colourful lanterns, and a public holiday atmosphere across the island.
