Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at the market square, 11 km from the airport (OUL): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest in July, August and December; quietest from January to April.

Then and now

Oulu's December days now average -2.2°C, 3.6°C warmer than in 1981–1990. 5 of 12 months are clearly warmer.

Getting there

How far Oulu is, and what it costs, depends on where you set off from — the months above do not.

Before you go

Type C and F plugs at 230 V. Drives on the right. The currency is the Euro. No UK Foreign Office advice against travel. Everything for Finland: cost of living, languages, emergency numbers and health.

Being there

On arrival

Paying — Finland uses the euro. Cards and phone payments are accepted almost everywhere, even in taxis and at market stalls, Visa and Mastercard most widely; carry a few coins or small notes for rural places. A place that takes no cash usually shows a sign saying Ei käteistä.
UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
Tipping — Not expected, as service is always included in the bill; people may round up or leave a couple of euros for great service.

Getting around Oulu

Apps — Rides: Bolt, FixuTaxi, Menevä, Taksi Helsinki, Uber. Maps: Google Maps, Apple Maps. Messages: WhatsApp, Messenger. Taxi prices vary widely: each taxi shows its price list on its right-hand side, headed by the price of a 10 km, 15-minute example trip, so compare before you get in, and choose a fixed price when booking in an app. At Helsinki Airport, the official partner firms' taxis wait at the rank off the arrivals hall, about €40 to €45 to the centre; Uber, Bolt and pre-booked taxis pick up in the P2 parking hall.

For being the fifth largest city in Finland the city centre is small compared to, say, Tampere or Turku. The whole of the city centre is easily walkable, and the walking conditions are good. More on Wikivoyage

What Oulu is like

Oulu (Swedish: Uleåborg) is the biggest city in Northern Finland, with about 210,000 inhabitants (in 2021). Once known for wood tar and salmon, Oulu has become a major high-tech centre, particularly in IT and wellness technology. Oulu has been selected as the European Capital of Culture for 2026. More on Wikivoyage

Worth seeing: Market Square (Kauppatori) is a hotch-potch of styles: old red granaries, renaissance revival architecture and 1970s brutalist concrete. More on Wikivoyage
Worth doing: Oulu City Theatre (Oulun Kaupunginteatteri), Kaarlenväylä 2. Plays in Finnish. Prices vary from €15 to €40 for a single adult ticket. More on Wikivoyage
Getting in: Oulu is on the main north-south railway, and train may be the most convenient way to get in from southern Finland, e.g. Helsinki, Tampere and Turku. There are flights from Helsinki, dominated by work-realated travel. More on Wikivoyage
Staying safe: Oulu is, on the whole, a very safe city, but avoid getting into arguments late in the night in fast food joints. More on Wikivoyage
