The climate in Somerset, USA, can be described as temperate with four distinct seasons. Visitors should expect significant temperature fluctuations throughout the year. Winters are cool, with average temperatures around 1-3°C in January and December, occasionally dropping below freezing.

Spring and autumn in Somerset are pleasant transitional periods. In the spring, temperatures gradually rise, reaching a comfortable 17°C by May. Autumn brings a gradual cooling, with pleasant temperatures of 20°C in September giving way to cooler weather by November. These seasons are ideal for walking and exploring the city.

Each month sees a small amount of precipitation, around 3-4 mm, but the number of days with precipitation ranges from 9 to 15 per month. This suggests that rain is likely frequent but light. Therefore, when planning a trip to Somerset, it is worth bringing light waterproof clothing regardless of the time of year.

Somerset experiences a distinct change of seasons with a noticeable annual temperature range. The coldest month is typically January, when the average temperature is about 1.0°C, night-time lows can drop to -2.5°C, and daytime highs reach around 4.5°C. Conversely, July brings the hottest weather: average temperatures reach 25.3°C, with daytime peaks up to 30.0°C and night-time temperatures not falling below 20.6°C. Thus, the annual temperature cycle presents a classic temperate climate pattern with clear winter cold and summer warmth.

Summer months in Somerset, particularly June, July, and August, are characterized by warm and occasionally hot weather. Average daytime highs range from 26.9°C in June to 30.0°C in July, creating comfortable conditions for outdoor activities, though it can sometimes be quite sweltering. The winter period, covering December, January, and February, brings cool and sometimes frosty weather. Average temperatures in these months range from 1.0°C to 3.1°C, with night-time frosts being common, especially in January when the average minimum is -2.5°C. Daytime temperatures in winter usually stay just above freezing, but can also hover around 0°C.

The transitional seasons—spring and autumn—are marked by gradual temperature changes. Spring, from March to May, sees a steady warming trend: from an average of 6.1°C in March to a pleasant 17.0°C in May. In autumn, from September to November, temperatures gradually decline: from a comfortable 20.3°C in September to a cool 7.7°C in November. Temperature fluctuations between day and night are most noticeable in the spring and early summer months (April, May, June), when the difference between the average daily high and low can reach 10°C. During other months, daily temperature variations are also present but typically smaller, averaging 7-9°C.

In Somerset, USA, precipitation is distributed fairly evenly throughout the year, with no pronounced rainy or dry season. Monthly precipitation fluctuates only slightly, mostly between 3 and 4 mm. This indicates that the city receives a small but steady amount of moisture year-round.

In terms of frequency, the highest number of days with precipitation occurs in July—averaging 15 days. The spring months of April and May, as well as June, are characterized by relatively frequent precipitation, with 12 to 13 rainy days each. March and December also see about 12 days of precipitation, which can fall as either rain or snow. The fewest days with precipitation are in October and November—9 days each—making them the "driest" months in terms of frequency, although the total precipitation in these months (4 mm and 3 mm respectively) remains comparable to other periods.

The nature of precipitation changes with the season. In the winter months, especially January (average temperature 1.0°C, minimum -2.5°C) and December (average temperature 3.1°C, minimum -0.4°C), as well as February, precipitation may fall as snow or sleet. Throughout the rest of the year, from spring to autumn, when temperatures are much higher, precipitation falls primarily as rain. Given the low total monthly precipitation (3-4 mm), it is likely that these are mostly light to moderate showers rather than heavy downpours.

When planning a trip to Somerset, it is important to consider the variability of the local weather throughout the year. The key packing principle is layering. Regardless of the season, you will need comfortable walking shoes. Since Somerset often has days with precipitation (averaging 9 to 15 per month), a light waterproof jacket or umbrella will be a reliable companion. However, the total amount of precipitation is usually low (3-4 mm per month), which typically indicates light drizzle or mist rather than heavy downpours.

In winter (December to February), average temperatures hover around 1-3°C, and minimums can drop below freezing, so be sure to pack a warm jacket, hat, gloves, and a scarf. During the summer months (June to August), the weather in Somerset is warm, and it can be hot in July and August: average temperatures are 22-25°C, with maximums reaching 30°C. For this period, light and breathable clothing such as T-shirts, shorts, and sundresses is ideal. Don't forget sunscreen, sunglasses, and a hat. Even in summer, evenings can be cool, so a light sweater or cardigan will be very useful.

Spring (March–May) and autumn (September–November) in Somerset are transitional periods. Average temperatures in the spring gradually rise from 6°C in March to 17°C in May, while in the autumn, they decrease from 20°C in September to about 8°C in November. Layering is especially relevant during these seasons: T-shirts, long-sleeved shirts, sweaters, and a mid-season jacket will allow you to easily adapt to temperature changes throughout the day and stay comfortable.
