A first look at Thessaloniki

Use Saturday for the centre and waterfront, then give the upper town a separate Sunday outing. The plan leaves room for a meal and one substantial museum instead of packing every historical period into the same morning.

Weather guide

Weather in Thessaloniki

Hot summer afternoons and cool winters call for seasonal layers; waterfront wind and Ano Poli hills affect how an outfit feels. Monthly values are calculated from NASA POWER MERRA-2 gridded daily data for 1991–2020 at the city coordinates. They represent a regional model cell, not a city weather station. Street shade, coastal exposure, elevation and urban warmth can differ. Climate averages do not predict an individual trip.

19–23°C

Mild to warm days, with cooler mornings and evenings.

What this means for packing

October calls for long trousers and a removable mid-layer as mornings and evenings cool. A hooded shell is useful between the markets and museums; the upper-town walk needs reliable grip if paving is wet.

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

Clothing planning bands use the calculated mean daily maximum (21.03°C) and minimum (11.65°C), rounded then expanded by 2°C each way. These are outfit prompts, not forecast limits or confidence intervals. Monthly values are calculated from NASA POWER MERRA-2 gridded daily data for 1991–2020 at the city coordinates. They represent a regional model cell, not a city weather station. Street shade, coastal exposure, elevation and urban warmth can differ. Climate averages do not predict an individual trip. Mean monthly precipitation is 48.91 mm, with 7.2 model days of at least 1 mm; precipitation includes water-equivalent snowfall. Complete daily records were checked before averaging all thirty years.
