The climate in Chantilly, located in France, can be described as temperate maritime, with four distinct seasons. There are no extreme temperatures here: winters are fairly mild, and summers are warm but not scorching. Travelers can expect comfortable weather for walks and sightseeing most of the year.

Winters in Chantilly are cool, with the average temperature in January being around 4.8°C, and in December and February about 5.9-6.1°C. Spring brings gradual warming: in March, the average temperature rises to 7.9°C, and in May, it reaches 13.7°C. Summer is the warmest season, with average temperatures around 19.6°C in July and August, while maximum daytime temperatures can reach a comfortable 22-25°C. In autumn, the temperature gradually drops from 16.6°C in September to 8.0°C in November.

One characteristic feature of the weather in Chantilly is the relatively even distribution of precipitation throughout the year, although the total amount is small—only 2-3 mm per month. At the same time, the number of "wet days" varies from 9 in July to 16 in December. This suggests that precipitation most often falls as light rain or drizzle rather than heavy downpours. Thus, although there is a chance of encountering rainy weather year-round, especially during the autumn and winter periods, prolonged spells of bad weather are usually not observed.

Chantilly experiences a temperate climate with noticeable seasonal temperature fluctuations throughout the year. The warmest months are traditionally July and August, when the average temperature stays around 19.6°C. During these summer peaks, daytime highs average a comfortable 24.4-24.6°C. On the other hand, the coldest month is January, when the average temperature is about 4.8°C, and average nightly lows drop to 2.3°C.

The summer period in Chantilly, covering June, July, and August, offers pleasantly warm weather. Daytime temperatures range from 22.7°C in June to 24.6°C in July, providing excellent conditions for outdoor activities and sightseeing. Nights bring refreshing coolness, with average minimum temperatures from 13.2°C to 14.8°C. Winter, from December to February, is characterized by cool weather. Average daytime highs during this period vary from 7.2°C in January to 9.4°C in February, while nightly temperatures can drop to 2.3-3.7°C. It is worth noting that temperature fluctuations between day and night are more pronounced in the summer months, when the difference between the average maximum and minimum temperature can reach about 10°C (for example, in July: 24.6°C max and 14.7°C min), while in winter this gap is slightly smaller, around 5-6.5°C.

In Chantilly, precipitation falls in relatively small amounts throughout the year, meaning there are no distinct wet or dry periods in terms of total volume. Although the monthly amount of moisture is usually low, this indicates that when precipitation does occur, it is generally neither intense nor overly prolonged.

Despite the modest total volumes, rainy days in Chantilly are recorded quite frequently. The highest number of such days occurs in December (averaging 16 days) and March (15 days). October also stands out: with 14 rainy days, its total precipitation reaches 3 mm, the same as in December. The lowest frequency of precipitation is typical for July, when an average of about 9 rainy days are recorded, while their total volume remains at the 2 mm level typical for most months.

During the winter period, especially in January (with an average minimum temperature of 2.3°C), February (2.8°C), and December (3.7°C), when air temperatures approach or drop below freezing, this light precipitation may fall as light snow or sleet. However, given the low overall volume, heavy snowfall should not be expected. In other seasons, precipitation is predominantly in the form of rain.

When planning a trip to Chantilly, it's important to consider the local climate to ensure your stay is as comfortable as possible. Since the number of rainy days is quite high throughout the year (from 9 to 16 days per month) despite the low total rainfall (2-3 mm per month), a light waterproof jacket or a compact umbrella will be your faithful companions. Regardless of the season, comfortable walking shoes are absolutely essential for sightseeing. The principle of layering will also come in very handy, allowing you to easily adapt to temperature changes throughout the day, especially during the shoulder seasons.

In summer (June-August), Chantilly is usually warm, with average temperatures around 18-20°C and maximums reaching 23-25°C. Light and breathable clothes are suitable for this period: T-shirts, shorts, skirts, sundresses, and light trousers. Don't forget sunscreen, a hat, and sunglasses. For the evening or cooler days, it's worth bringing a light sweater, cardigan, or thin jacket. In spring (March-May) and autumn (September-October), the weather is more changeable, with average temperatures from 8°C to 17°C. During these times, T-shirts, long-sleeved shirts, jumpers, and a medium-weight jacket that can be easily taken off or put on will be relevant.

In winter (from November to February), Chantilly becomes significantly cooler: average temperatures stay in the 4-8°C range, and minimums can drop to 2-3°C. During this period, you will need warm clothes: sweaters, fleeces, a warm waterproof jacket or coat, as well as a hat, scarf, and gloves. Given the frequent, though not heavy, precipitation and the increased number of wet days, especially in December (16 days), waterproof outerwear will be particularly useful to ensure your walks around charming Chantilly remain pleasant.
