Real-time weather conditions and forecasts for major cities across Sri Lanka. Plan your trip around the best weather.
Sri Lanka has two monsoon seasons that affect different coasts. The southwest monsoon (May-September) brings rain to the west and south coasts, while the northeast monsoon (October-January) affects the east coast. Understanding these patterns helps you plan the perfect trip with minimal rain and maximum sunshine.
West & South Coast (Colombo, Galle, Mirissa): Best from December to April with dry, sunny weather perfect for beaches and nightlife. Expect temperatures 28-32°C, calm seas, and ideal conditions for whale watching, snorkeling, and beach clubs.
East Coast (Arugam Bay, Trincomalee): Best from May to September for surfing, beach parties, and clear skies. This is peak surf season with consistent swells, warm water (28-30°C), and low rainfall.
Hill Country (Kandy, Ella, Nuwara Eliya): Pleasant year-round with temperatures between 15-25°C. Wettest months are October-December. January to March offers the clearest skies for hiking and train rides.
January - February: Peak season for the west and south coasts. Perfect beach weather (29-31°C), minimal rain, busy tourist season. Book hostels and coworking spaces early. Great for Colombo nightlife, Galle Fort exploration, and whale watching tours from Mirissa.
March - April: Hot and humid (32-34°C) before the southwest monsoon. Still dry but temperatures peak. Excellent for early-morning surfing, evening beach parties, and exploring cultural sites before crowds. Yala National Park is fantastic for leopard sightings due to low water levels.
May - September: Southwest monsoon affects Colombo, Galle, and Mirissa with afternoon thunderstorms. Switch to the east coast! Arugam Bay surf season peaks June-August. East coast hostels fill up fast. Temperatures stay warm (28-30°C) with brief showers.
October - November: Intermonsoon period with unpredictable weather across the island. Occasional heavy rain, shorter dry spells. Great for budget travelers \u2014 lower prices, fewer tourists, lush green landscapes. Hill country gets very wet; pack rain gear.
December: Transition back to dry season on the west/south coasts. Weather stabilizes by mid-month. Christmas and New Year events draw crowds to Colombo beach clubs and Galle nightlife. Book accommodation 2-3 weeks ahead.
Beach Season (West/South Coast Dec-Apr, East Coast May-Sep): Lightweight cotton or linen clothes, swimwear, reef-safe sunscreen (SPF 50+), wide-brimmed hat, flip-flops and sandals, sunglasses (UV protection), light beach cover-up for temple visits, mosquito repellent (especially at dusk), and a reusable water bottle.
Hill Country (Ella, Kandy, Nuwara Eliya): Long pants and a fleece jacket (evenings drop to 10-15°C), closed-toe walking shoes or trail runners, rain jacket or poncho (rain is common), layers for temperature changes, and a small daypack for hikes.
Monsoon Season Travel: Compact travel umbrella, waterproof phone case, quick-dry clothing, waterproof sandals (Tevas or Chacos), ziplock bags for electronics, and an extra set of dry clothes in your day bag.
Year-Round Essentials: Universal power adapter (UK 3-pin plugs), first-aid kit with anti-diarrheal meds, prescription medications (bring extra), headlamp or small flashlight (power cuts happen), photocopies of passport and visa, and travel insurance documents.
Dry Season Activities (Dec-Apr West/South, May-Sep East): Surfing, scuba diving and snorkeling, whale and dolphin watching, beach parties and nightlife, hiking (Adam\'s Peak, Ella Rock), safari tours (Yala, Udawalawe), temple and cultural tours, coworking from beach cafes with reliable WiFi.
Monsoon Season Activities (Indoor & Flexible): Cooking classes, Ayurvedic spa treatments, museum and art gallery visits, coworking from indoor spaces in Colombo, shopping in covered markets, short hikes with rain gear, yoga and meditation retreats, and exploring less-touristy inland towns.
