Summer in Warsaw is generally warm and pleasant, with average temperatures in July and August around 20°C, sometimes reaching 25°C and above.

Regarding precipitation, it is distributed quite evenly throughout the year, although summer months, such as July and August, can be slightly wetter. On average, the number of rainy days ranges from 9 to 15 per month. This means light rain is possible at any time of the year, so tourists are advised to carry an umbrella or a raincoat, especially if the trip is planned for a longer period.

Conversely, the warmest months are July and August, with average temperatures around 20.1°C - 20.2°C. In August, daytime temperatures can reach an average of 25.1°C, making it the peak summer month.

The summer months in Warsaw, especially from June to August, offer residents and visitors a pleasantly warm time.

Summer nights also remain warm, with minimum temperatures dropping to an average of 14.1°C - 15.4°C.

Precipitation in Warsaw is distributed quite evenly throughout the year, and according to the provided data, the total monthly amount is low. There is no distinct rainy season or dry period in the city, although there are some fluctuations in the amount of precipitation and the number of wet days from month to month.

Winter months, such as January (2 mm of precipitation, 15 wet days), December (2 mm of precipitation, 13 wet days), and February (2 mm of precipitation, 12 wet days), are characterized by frequent but, judging by the figures, light precipitation. Given average temperatures close to zero or below, snowfall or mixed precipitation is quite likely during this period. The highest number of wet days occurs in January.

The summer months, July and August, are the "wettest" in terms of average rainfall (3 mm each). July also sees a significant number of days with precipitation — 14 days, making it one of the rainiest months in terms of frequency. Spring and autumn months show lower precipitation amounts; for example, March, April, and November are the "driest" by volume (1 mm each). At the same time, March and November also have the fewest wet days in the year — 9 days each. Overall, one can expect precipitation in Warsaw at any time of year, but it is generally not excessively heavy.

When planning a trip to Warsaw, it is important to choose your wardrobe correctly to feel comfortable in any weather. Given the moderately continental climate of the capital of Poland, the key principle is layering. Regardless of the season, comfortable shoes for long walks around the city are an absolute necessity. Also, since precipitation in the form of rain or snow is possible all year round (averaging 9 to 15 wet days per month), a compact umbrella or a light raincoat will become your faithful companions.

If your trip falls during the winter months (December-February), when the average temperature hovers around 0°C and can drop lower, be sure to bring warm outerwear: a winter jacket or coat, a hat, a scarf, and gloves. Warm sweaters, fleece tops, and thermal underwear will not be amiss, especially if you plan to spend a lot of time outdoors. For a summer visit (June-August), when the average temperature rises to 20-25°C, light clothing is suitable: t-shirts, shorts, dresses, and sandals. However, even in summer, evenings can be cool, so bring a light jacket or cardigan. Don't forget sunscreen and a hat for sun protection.

Spring (March-May) and autumn (September-November) in Warsaw are transitional seasons with changeable weather. In early spring and late autumn, it can be quite cool (average temperature in March is about 4°C, in November about 5°C), so a mid-season jacket, sweaters, jeans, or thick trousers will come in handy. In May and September, the weather is usually milder and warmer (average temperature 14-15°C), but a light jacket or windbreaker will still be useful. During these periods, the principle of layering is especially relevant, allowing you to easily adapt to temperature changes throughout the day.
