Each cell is that destination's own verdict for the month — sweet spot, ok or avoid — with its typical daily high, from the same ten years of climate readings its page is built from. A dot marks a busy month. The last row counts the sweet spots, and the best months are marked.

On arrival

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.
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.
Getting around Helsinki — I and P commuter trains run from the airport station, by lift or escalator from the terminal, to Helsinki Central Station in about 30 minutes, and HSL bus 600 runs round the clock from the bus station in front of arrivals to the centre in about 40. Both need an HSL ticket for zones ABC: show a contactless bank card to an HSL card reader for an adult single, or buy one in the HSL app, at the ticket machines by the platforms or at the R-kioski in arrivals; cash is not taken. The same ticket covers trams, buses, the metro, commuter trains and the Suomenlinna ferry.
Tipping — Not expected, as service is always included in the bill; people may round up or leave a couple of euros for great service.
Emergency — 112 (any emergency).
TravelCharika is not an emergency service: we cannot call for help or send anyone. Numbers can change; if one fails, ask someone local or your hotel.

Every verdict here is the destination's own: ten years of climate readings, the public holidays that crowd it, and what the flight costs. Nothing is said about Finland as a whole that was not first measured at each place in it.
