During the winter months, such as January, February, and December, average temperatures often drop below freezing or stay near that mark. Therefore, precipitation during this time is likely to fall as snow or sleet. In March, with its transitional weather, both rain and late-season snowfalls are possible. From April to November, when temperatures are consistently above freezing, precipitation primarily occurs as rain.

Despite the fact that the total amount of precipitation in Cambridge is low (from 2 to 4 mm per month), it happens quite regularly. The highest volume of precipitation, about 4 mm, is recorded in January, March, April, July, October, and December. The "driest" month in terms of precipitation volume is May (about 2 mm). In terms of frequency, April and July stand out with approximately 13 days of precipitation. The lowest number of rainy days (about 8) falls in November. Thus, while heavy downpours are unlikely, light precipitation can be expected on 8–13 days every month.

When planning a trip to Cambridge, it's important to consider New England's changeable weather. The key to a comfortable journey is layering your clothes, as temperatures can shift noticeably throughout the day. Regardless of the season, you'll need comfortable shoes for walking through historical streets and campuses. Given that Cambridge sees between 8 and 13 days of precipitation each month, don't forget to bring an umbrella or a light waterproof jacket. While total rainfall is generally low, it's best to be prepared for a sudden shower.

In winter (from December to February), Cambridge is quite cold, with average temperatures hovering around freezing and nighttime frosts. You will definitely need a warm winter jacket, hat, gloves, scarf, and warm sweaters. Waterproof and insulated footwear will also come in handy, especially if it snows. Summer (from June to August) is warm and pleasant, with average temperatures around 20–23°C. Pack light clothing: T-shirts, shorts, and dresses. However, evenings can be cool, so a light sweater or jacket will be useful. Don't forget sunscreen and a hat for sun protection.

Spring (from March to May) and autumn (from September to November) are transitional seasons with unpredictable weather. In early spring (March) and late autumn (November), it is still quite chilly, so a mid-season jacket, sweaters, and perhaps warm accessories will be useful. In May and September, the weather is usually mild and comfortable for walking, but a light jacket or windbreaker won't go amiss, especially on windy days. The principle of layering is particularly relevant here, allowing you to adapt to temperature changes during the day. During these seasons, it's also worth being prepared for breezy conditions, so windproof clothing can prove very helpful.
