Bacau is characterized by a temperate-continental climate with clearly defined seasons. The weather here is generally favourable for tourism: summer delights with warmth, and winter brings real frosty freshness, but without extreme cold. Throughout the year, there is a significant temperature variation, so the choice of clothing for the trip will depend heavily on the season.

The warmest period lasts from June to August, when daytime temperatures often rise to 26-27°C. However, the beginning of summer can be a bit humid: June stands out with the highest number of rainy days. Autumn arrives gradually, with October often being one of the driest months, making it a great time for walking. Winters in the region are cool, with average temperatures around zero and night frosts, creating the atmosphere of a true European winter.

The climate in Bacau is characterized by distinct seasonality, offering travellers diverse weather conditions depending on the time of year. The coldest month is January with an average temperature of around -0.3°C, when night frosts can reach -3.9°C. Summer, on the contrary, brings significant warming: August is considered the hottest month, when averages are 22.0°C, and daily maximums regularly rise to 27.6°C.

The summer period in this region of Romania can be described as pleasantly warm, without extreme heat. In June, July, and August, the daytime temperature stays comfortably in the range of 25–27°C, which is ideal for sightseeing. It is worth noting noticeable fluctuations between day and night temperatures: even at the height of summer after sunset, the air cools down to 15–16°C, bringing welcome freshness.

Winters here are moderately cool and quite mild. During the day, the air often warms up to above-zero temperatures (from 3°C to 6°C), however, at night it consistently drops slightly below freezing. Transitional seasons, such as May and September, delight with the most balanced weather with average temperatures from 15°C to 16.8°C, creating favourable conditions for long walks.

Precipitation in Bacau is distributed throughout the year quite typically for Romania's continental climate. Winter months, especially December and January, bring snow, as temperatures often drop below zero. Although the number of days with precipitation in winter is moderate (about 8–9 days per month), the volume is small, which creates a pleasant winter atmosphere without excessive snowdrifts.

The wettest period of the year falls at the beginning of summer. June is the record holder for precipitation frequency: it rains on average 13 days a month. In July, the situation is similar (about 12 rainy days). Summer precipitation often falls in the form of short but intense showers or thunderstorms, which quickly refresh the city after the daytime heat, so an umbrella will come in handy during your trip.

The driest and most comfortable time for long walks can be found in the middle of autumn. In October, the lowest number of rainy days is recorded — only about 5 per month. This is the ideal time for open-air sightseeing, as the probability of getting caught in the rain is minimal, before precipitation frequency starts to increase again in November.

When packing for Bacau, consider the distinct seasonality of the local climate. Summer here is usually warm and comfortable, with temperatures reaching 27°C in August, so light clothing made of natural fabrics, sunglasses, and sunscreen will be essential. However, the beginning of summer, especially June, can be quite rainy, so it is worth putting a compact umbrella or a light raincoat in your suitcase so that sudden precipitation does not disrupt your plans.

Winters in this region of Romania are cool, often with temperatures below zero, especially in January. For comfortable walks in the cold season, be sure to take a warm windproof jacket or down coat, as well as a hat, scarf, and gloves. Pay special attention to footwear: it should be comfortable, warm, and preferably waterproof, as humidity and slush are not uncommon in winter.

For trips in spring and autumn, when the weather can be changeable, it is best to stick to the principle of layering. A combination of a T-shirt, jumper, and windbreaker will allow you to quickly adapt to temperature changes during the day: from a cool morning to a warm afternoon. And, of course, in any season you will need a pair of trusted comfortable shoes for long walks through city streets and parks.
