When planning a trip to Hartford, it is important to prepare for changeable weather, which requires a thoughtful approach to packing. The key principle is layering, as the temperature can fluctuate noticeably throughout the day, especially during the transitional seasons. Regardless of the time of year, comfortable shoes for walking around the city will be your indispensable companion. It is also worth taking a compact umbrella or a light waterproof jacket: although the monthly amount of precipitation is usually small (2-4 mm), Hartford has between 7 to 12 "wet days" per month, indicating frequent, albeit not heavy, precipitation.

Winter months (December to February) in Hartford are cold, with average temperatures below freezing (for example, around -4.8°C in January, while minimums can drop to -8.3°C) and a likelihood of snowfall. During this period, you will need a warm winter jacket or down coat, a hat, a scarf, gloves, and insulated shoes. In summer (June to August), the weather is usually warm, sometimes hot. Average temperatures hover around 20-23°C, and can reach 27.4°C in July. Light, breathable fabrics such as cotton or linen are the ideal choice. Don't forget sunscreen, a hat, and sunglasses. Even in summer, a light sweater or cardigan may be useful for cool evenings or visiting air-conditioned premises.

Spring (March-May) and autumn (September-November) are the seasons with the most variable weather. In March (average temperature around 2.7°C) and November (around 4.1°C), it is still quite cool, so a mid-season jacket, sweaters, and jeans will be very handy. In April (average temperature 7.7°C), May (15.3°C), September (18.6°C), and October (11.8°C), daytime temperatures can be comfortable, but evenings remain cool. In these months, the principle of layering is especially relevant: a light jacket, cardigan, or fleece top will allow you to easily adapt to temperature changes throughout the day.
