When planning a trip to Markham, it is important to consider the variable weather typical of Canada. Layering should be your key packing principle, allowing you to stay comfortable during both cool mornings and warmer afternoons. Regardless of the season, comfortable walking shoes are a must, as the number of wet days per month is quite significant (from 8 to 13), suggesting potential precipitation. A light waterproof jacket or a compact umbrella will also come in handy year-round.

For trips during the warm season, from late spring to early autumn (May-September), when average temperatures range from 13.6°C to 21.8°C, pack light clothing: t-shirts, shorts, dresses, and a light sweater or cardigan for the evenings. Sunscreen and a hat are essential, especially in the summer months (June-August) when maximum temperatures can reach 26.3°C. Despite the warmth, don't forget the possibility of rain—a light windbreaker or raincoat won't take up much space.

During the cold months, from late autumn to early spring (November-March), average temperatures drop significantly, ranging from 3.7°C to -4.7°C, with minimums reaching -8.3°C. During this period, warm clothing is necessary: a winter jacket (preferably windproof and waterproof), a hat, gloves, a scarf, and warm sweaters. Thermal underwear can be a great addition. Given the frequent precipitation in the form of snow or sleet, be sure to bring waterproof and warm footwear. The transitional seasons, April and October, require special attention to layering, as the weather can be unpredictable.
