Precipitation in Trois-Rivières falls fairly evenly throughout the year, with no distinct rainy or dry season. Monthly precipitation is modest, ranging between 2 and 4 mm. The summer months (June, July, August), as well as April and October, generally receive slightly more precipitation (4 mm), while May is the month with the lowest average rainfall (2 mm).

The frequency of precipitation is also relatively stable, with most months seeing 12 to 13 precipitation days. July stands out as the month with the highest number of "wet" days—averaging 15. On the other hand, September sees the fewest days with precipitation—around 9. The nature of the precipitation depends directly on the time of year: in the cold months, roughly from November to March, when average temperatures drop significantly below zero (e.g., January at -9.8°C, December at -5.8°C), precipitation falls primarily as snow. With the arrival of warmer weather from April to October, precipitation turns into rain.

Despite the small difference in total volume, the "wettest" months by precipitation amount (4 mm) are April, June, July, August, and October. Given the low overall millimeter readings even during these periods, it can be assumed that precipitation in Trois-Rivières is usually not intense. In winter, this likely means light to moderate snow, and during the warmer months, short-lived showers.

When planning a trip to Trois-Rivières, it is important to consider the significant seasonal temperature fluctuations and frequent precipitation. Winter (December to February) can be quite harsh: average temperatures drop well below zero, sometimes reaching -14°C. Therefore, your suitcase must include very warm, windproof, and waterproof outerwear, thermal underwear, wool sweaters, a hat, scarf, and gloves. Don't forget insulated and waterproof footwear, as snow and slushy days are common, with 12–13 days of precipitation per month, even if the total amount is small.

Spring (March–May) and autumn (September–November) in Trois-Rivières are characterized by changeable weather, so the principle of layering will be very useful. You will need medium-weight items: jackets, fleece sweaters, jumpers, as well as a light hat and gloves, especially in early spring and late autumn. In summer (June–August), the weather turns warm, with average temperatures around +20°C, reaching up to +26°C in July. Light T-shirts, shorts, and dresses are suitable for this season, along with sunscreen and a hat. Don't forget to pack a light jacket or sweater for evening walks. Regardless of the season, comfortable walking shoes are your best companion. Since the number of days with precipitation remains high year-round (9 to 15 days per month), even with low total volume, a compact umbrella or a light raincoat will be indispensable accessories for your trip.
