The climate in Quincy (USA) can be described as temperate with four distinct seasons. There is a noticeable contrast between the seasons here: winters are cool, with temperatures periodically dropping below freezing, whilst summer delights with stable warmth and sunny days. This weather pattern allows for planning a variety of holidays depending on the month of your visit.

The summer season, lasting from June to August, is the warmest period, when the air during the day often warms up to a comfortable 29–30°C. Spring and autumn serve as mild transitional periods. It is worth noting that May is usually the month with the highest number of rainy days, so an umbrella during a spring trip will not go amiss. September, on the contrary, often offers pleasant conditions with agreeable temperatures and less rainfall, making the beginning of autumn an excellent time for a visit.

The temperature regime in Quincy demonstrates distinct seasonality, characteristic of a continental climate. The annual cycle covers a wide range of temperatures: from frosty winters to truly hot summers. The coldest month is January with an average temperature of around -1.3°C and night-time drops to -5.4°C. The peak of the heat falls in July, when average figures reach 25.6°C, and the daily maximum often exceeds the 30°C mark.

Summer in the city can be described as hot and stable. Between June and August, daytime temperatures regularly rise to 29–30°C, whilst nights remain sufficiently warm (around 19–21°C), creating comfortable conditions for evening walks, though it can be tiring without air conditioning. The winter period, conversely, requires warm clothing: from December to February, the thermometer often hovers around zero, periodically dipping into negative values, especially during the night hours.

Throughout the year, there is a noticeable but not extreme difference between day and night temperatures, which usually ranges from 5 to 10 degrees. For example, in May or September, the air during the day can warm up to a comfortable 24–26°C, but after sunset, it quickly freshens to 14–16°C. Travellers planning long walks during the off-season are advised to carry a light jacket or sweater to feel cosy when the time of day changes.

Precipitation in Quincy is distributed fairly evenly throughout the year, however, the character of the weather changes significantly depending on the season. Winter months, especially January and February, are characterised by low temperatures, often dropping below freezing. During this period, precipitation mainly falls as snow, with snowy or overcast days occurring on average about 8–9 times a month.

Spring marks the transition to a wetter season. As it gets warmer, the frequency of precipitation increases, reaching its peak at the end of the season. The rainiest month of the year is May: at this time, you may need an umbrella for approximately 14 days per month. This is the period when nature receives the most moisture before the onset of summer.

Summer and early autumn bring some reduction in the frequency of rainfall. June, July, and August remain warm, with a moderate number of rainy days (around 9–10). The driest month of the year is considered to be September, when the number of days with precipitation drops to a minimum — on average to 6 days, making the beginning of autumn an excellent time to visit the city.

Packing for a trip to Quincy requires attention to the season, as the weather here changes quite noticeably throughout the year. In winter and early spring, when temperatures can drop below freezing, you will definitely need a warm windproof jacket, a hat, and gloves. Since the off-season is often changeable, the best strategy is the principle of layering: bring items that are easy to combine, such as t-shirts, jumpers, and a light windbreaker, to quickly adapt to temperature changes during the day.

Summer in the city can be quite hot, with daytime temperatures reaching 30°C, so light clothing made from natural fabrics, sunglasses, and sunscreen will be simply essential. Do not forget comfortable shoes for long walks. Given that even in the warmest months (especially in May and June) the number of rainy days remains high, a compact umbrella or raincoat will become your faithful companions on any trip, protecting you from sudden rain.
