What this means for packing

Choosing a season

The best-season badge suggests months for general sightseeing, using the typical daytime temperatures and rainfall in our monthly guides. Beach holidays, festivals, winter sports and northern lights trips may suit different dates.

Climate methodology

Packtricia calculated October city-area ERA5 averages via Open-Meteo for 1991–2020: mean daily high 12.3°C, mean daily low 5.1°C and mean monthly precipitation 45.1mm. Thirty complete year-months contribute equally: daily maximum/minimum means and monthly precipitation sums are averaged across years. Requested coordinates 52.2297,21.0122 returned grid 52.25,21. Modelled grid estimates are not local station normals. Packing bands extend rounded means by 2°C either way, not forecasts or limits on extremes. Monthly precipitation is not daily rain probability. Actual trip weather and park or square exposure matter.
