When planning a trip to Charlottetown, it is important to consider the changeable weather throughout the year. The key is layering your clothing, which will allow you to feel comfortable amidst temperature fluctuations.

A light waterproof jacket or umbrella will also be useful year-round. In the summer months, do not forget sunscreen and headwear.

For a visit to Charlottetown during the cold season, from December to March, as well as in November when average temperatures drop close to zero or below, you will need warm clothing. Pack a winter jacket (preferably windproof and waterproof), sweaters, fleece tops, thermal underwear, warm trousers, a hat, a scarf, and gloves. Warm waterproof footwear is critically important, especially considering the number of days with precipitation, which in winter can mean snow or wet snow. Transitional months, such as April and October, also require warm items and layering, as the weather can be cool.

The summer months, from June to August, in Charlottetown are usually warm and pleasant, with average temperatures around 15-20°C and highs reaching 23°C. During this period, you will need t-shirts, shorts, light trousers, or dresses. However, evenings can be cool, so a light jacket, cardigan, or sweater will be very handy. Even in summer, rainy days are possible, so a compact umbrella or a light raincoat would not go amiss. In May and September, the weather is also quite mild, but the principle of layering remains relevant – it may be warm during the day, but cooler in the morning and evening.
