The climate in Plymouth, located in the USA, can be described as temperate, with four distinct seasons. This means you can expect noticeable weather changes throughout the year: from cool and snowy winters to warm and sunny summer months, as well as pleasant transition periods in spring and autumn.

Winters here are quite cold, with average temperatures around zero degrees Celsius, often accompanied by light snowfall. Spring brings gradual warming, while summer delights with warm days when the thermometer rises to an average of +20-23°C in July and August. In autumn, the weather becomes cooler but remains quite pleasant. Precipitation in Plymouth is distributed fairly evenly throughout the year, usually falling as frequent but light rain or snow, so the climate generally does not feature extreme downpours or droughts.

The temperature regime in Plymouth is characterized by distinct seasonality, ranging from frosty winters to comfortably warm summers. The coldest month of the year is traditionally January, with an average temperature of about -0.5°C, while the peak of heat occurs in July, when the air warms up to an average of +23.1°C. This annual range allows tourists to enjoy a variety of climate conditions depending on their chosen travel time.

The winter period here is quite cool but not extremely harsh. In January and February, night temperatures regularly drop below freezing, averaging -3.3...-3.6°C, while daytime figures hover around +2...+4°C. Spring brings a gradual warming: while March still retains a winter freshness (averaging +4.1°C), by May, pleasant weather sets in with daytime highs reaching +18°C.

Summer in Plymouth offers travelers gentle warmth without exhausting heat. In the hottest months, July and August, average daytime temperatures are a comfortable +25...+26°C, and nights remain warm — around +19°C, indicating minor daily temperature fluctuations during this season. September continues to hold the summer mood with an average of +19°C, but by November, the air cools significantly to +7°C, preparing the city for winter.

Precipitation in Plymouth is distributed remarkably evenly throughout the year, making it difficult to pinpoint a distinct rainy or dry season. Travelers should expect a moderate amount of moisture in any season. On average, the number of days with precipitation ranges from 8 to 12 per month, making the weather fairly predictable yet changeable.

In winter, when temperatures drop below freezing (especially in January and February), the nature of precipitation changes: instead of rain, it often snows. With the arrival of spring and rising temperatures, the rains return. The most frequent month for precipitation is April, which sees about 12 rainy days. Rains are also not uncommon in summer, but they are generally not too heavy.

If you are looking for the time with the lowest probability of precipitation, look to November — statistically, it is the driest month with about 8 inclement days. In other months, such as September or October, precipitation levels remain stable. We recommend always carrying an umbrella or raincoat when heading out for a walk in this historic US city.

The weather in Plymouth, as in all of New England, can be changeable, so the main principle when packing is layering. Even if you are traveling in summer, when average temperatures rise to a comfortable +23°C, evenings on the coast can be chilly due to the ocean breeze. Therefore, in addition to T-shirts and shorts, be sure to pack a hoodie, a light sweater, or a windbreaker. Given the many historical sites, you will need comfortable, broken-in shoes for long walks.

For a trip between late autumn and early spring, you should prepare for the cold. In winter, temperatures often drop slightly below freezing, so a warm windproof jacket, hat, scarf, and gloves will be essential for comfortable sightseeing. Spring and autumn are fairly mild here but require mid-season clothing that can be easily layered or removed depending on the weather's whims.

Precipitation in Plymouth occurs regularly throughout the year — on average, there are about 10–11 rainy days per month. Consequently, a compact umbrella or a quality raincoat will be your faithful companions regardless of the season. Also, don't forget sunscreen and sunglasses in the summer: the sun near the water can be intense even in cloudy weather, and swimwear will come in handy if you decide to relax on the local beaches.
