In Fredericton, the nature of precipitation changes noticeably throughout the year depending on the season. Winter months, from December to February, when average temperatures drop significantly below freezing (e.g., -6.9°C in January), bring precipitation mainly in the form of snow. Transitional periods, such as March (average temperature -1.2°C) and November (average temperature 2.1°C), can be characterized by mixed precipitation, where snow may alternate with rain or sleet. From April to October, when temperatures are consistently positive, precipitation falls as rain.

The frequency of precipitation in Fredericton remains noticeable throughout the year, although without extreme values. The highest number of days with precipitation occurs in June (an average of 14 days), as well as in January and July (13 days each). Precipitation is observed slightly less often in May and September – about 10 days in each of these months. During other periods of the year, one can expect from 11 to 12 days with precipitation. This regularity, combined with a generally low volume of monthly precipitation, emphasizes its predominantly light character, whether it is snow or rain.

Thus, although Fredericton has no pronounced rainy or dry season in terms of total moisture volume, the type and regularity of precipitation change. In winter, one should expect frequent but not heavy snowfalls, while in the warm season – light rains distributed over 10-14 days monthly.

When planning a trip to Fredericton, it is important to consider significant seasonal temperature fluctuations. In winter (from December to March), average temperatures drop below freezing, reaching -6°C to -7°C, so you will need very warm items: a winter jacket, thermal underwear, a hat, gloves, and a scarf. Also, do not forget waterproof shoes, as precipitation, although not abundant (3-4 mm per month), falls quite often (11-13 wet days per month). Spring (April-May) and autumn (September-November) are transitional seasons. In April, the average temperature is around 5°C, and in October – around 10°C. During these periods, layered clothing is recommended: sweaters, fleece jackets, a demi-season jacket, and a waterproof windbreaker.

Summer in Fredericton (from June to August) is warm and pleasant, with average temperatures from 17°C to 20.6°C. During the day, the temperature can rise to 22-25°C. For this time of year, light clothing, t-shirts, and shorts are suitable, but it is also worth taking a light jacket or sweater for evening walks, as nights can be cool. Considering that even in summer there are 11-14 days with precipitation, a light raincoat or umbrella will be useful. Regardless of the season, comfortable walking shoes are a must-have, as the city is conducive to walking.

Since the weather in Fredericton can be changeable, the principle of layering in clothing is your best ally. This will allow you to easily adapt to temperature changes throughout the day. Do not forget sunscreen and a hat in the summer months, as well as moisturizing cream for the skin, especially in the cold season. Given the frequency of precipitation, even if its volume is small, having an umbrella or a light waterproof jacket will make your stay more comfortable at any time of the year.
