Typical weather
What Colombo is usually like
What a typical day looks like, hour by hour: 8am when you get up, 2pm in the afternoon, 8pm when you are out in the evening — on Sri Lanka’s own clock, at Colombo. Ten-year averages (2011–2020) measured at the capital, so this is Colombo, not the whole of Sri Lanka, and a mountain or a coast a few hours away can be nothing like it. Averages, not a forecast: a typical January rather than any particular one.

Getting in, and staying safe
Visas, entry rules and health — the official pages
Entry rules, visa requirements, vaccinations and safety advice for Sri Lanka all live on the pages below. Each one goes straight to Sri Lanka, not to a search box.
We link to official sources and stop there. We do not check, summarise, rank or verify them — always read the official page itself before you travel, and read the one for your own nationality. We are an independent site with no government connection.

One way to see it
AdOrganised tours and day trips in Sri Lanka, on Viator — a way to see what is bookable and what other people rated. We earn a commission if you book through that link, and you pay exactly the same either way. We do not choose, rank or check what appears there, and nothing on this page changes because of it.
Worth knowing
Five things that hold almost everywhere
- Grab (or the local equivalent) beats street taxis in most of Asia — and even where you don't use it, the app price tells you what's fair.
- ATMs: withdraw big and rarely, always in the local currency, and always decline the machine's kind offer to charge your card in pounds — that 'service' costs 3–6%.
- eSIM before you land (Airalo or similar) so you're online at arrivals; swap to a local SIM if you're staying weeks.
- Scooters anywhere: without the right licence category your travel insurance is void. That's the whole conversation.
- Save the local emergency number on day one, and know which private hospital expats use in your city — ask your host the day you arrive.
