The climate in the city of Suwalki can be described as moderate with a noticeable continental influence. Seasonality is clearly expressed here: travellers can expect truly crisp winters and warm, but not sweltering, summers. Due to its location in the north-east of the country, this region is often characterised by slightly cooler weather compared to the rest of Poland, making it an excellent destination for those who dislike exhausting heat.

The summer period, especially July and August, is the most comfortable time to visit, when the air warms up during the day to an average of 23°C. In winter, the city is immersed in a frosty atmosphere with average temperatures below zero, especially in January and February. The transition seasons—spring and autumn—are quite cool but picturesque.

A characteristic feature of the local climate is stable humidity throughout the year. The number of days with precipitation varies from 10 to 17 per month, which suggests that rain (or snow in winter) is a frequent occurrence here, but usually short-lived. Tourists are advised to carry an umbrella or raincoat regardless of the chosen season so that changeable weather does not interfere with walks.

Spring and autumn serve as smooth transition seasons. By May, the air warms up to a comfortable 17°C during the day, while October brings freshness with average values around 9°C. Travellers should pay attention to the noticeable difference between day and night temperatures, especially in the summer months.

Precipitation in Suwalki is distributed fairly evenly throughout the year, although its character changes with the seasons. In winter, when the average temperature stays around or below zero (especially in January and February), precipitation most often falls as snow. January holds the record for the frequency of inclement days—snow or wet snow can fall for about 17 days a month, creating a persistent winter cover characteristic of this region of Poland.

With the arrival of warmth, precipitation turns into rain, which, as a rule, is not distinguished by high intensity. The most favourable months for walking can be called April and September: the lowest number of days with precipitation is recorded at this time (about 10 days per month). This is an excellent time for those who prefer drier weather for sightseeing.

However, rains here are often short-lived, refreshing the air on warm days. Travellers are recommended to have an umbrella or raincoat with them at any time of the year, as the weather can be unpredictable.

When packing for Suwalki, which is often called the "Pole of Cold" of Poland, you should take your wardrobe choice seriously, especially in the autumn-winter period. Winters here can be frosty and damp, so be sure to bring quality thermal underwear, a warm windproof down jacket, a hat, a scarf, and gloves. Considering that precipitation falls quite often (up to 17 days in January), waterproof and insulated shoes with non-slip soles will become your main ally when walking around the city streets.

Summer in this region is usually mild and comfortable, with daytime temperatures around 20–23°C, however, evenings can be cool. We recommend sticking to the principle of layering: a t-shirt or light shirt will be enough during the day, but it is always worth having a fleece jacket or windbreaker in your backpack. Since rain is possible in any season (on average 12–14 rainy days per month in summer), a compact umbrella or light raincoat are mandatory items in every traveller's suitcase.

To explore the picturesque surroundings and city attractions, choose the most comfortable shoes for walking, for example, broken-in sneakers or trekking boots. Even in cloudy weather, do not forget about skin protection, especially in summer, so grab sunscreen and sunglasses. In the off-season, the weather can be changeable and windy, so a spare pair of socks and a change of clothes will help you feel confident in any conditions.
