Arnhem

Planning your day in Arnhem or getting ready for a trip? In this section, you will find the most up-to-date weather information, detailed forecasts, and visual charts to help you prepare for any surprises from Mother Nature.

The climate in Arnhem, as in most regions of the Netherlands, can be described as temperate maritime. This means that there are four distinct seasons, but without extreme temperature fluctuations. Winters are generally mild, with average temperatures slightly above freezing, while summers are warm and pleasant, with average temperatures around 18-19°C and highs reaching 22-23°C in July and August.

One of the defining characteristics of the weather in Arnhem is the fairly even distribution of precipitation throughout the year. Although the amount of rainfall in millimeters is low (2-3 mm per month), the number of rainy days remains relatively high across all seasons, ranging from 11 to 16 days per month. This means that light rain or overcast skies can accompany you at any time of year, so it is worth being prepared for changeability and always having an umbrella or raincoat with you.

The temperature regime in Arnhem shows a clear change of seasons typical of a temperate climate. The annual temperature progression is smooth, without sharp jumps. The coldest month is usually January, when the average temperature stays at 4.3°C, with nightly lows dropping to 2.2°C and daytime highs rarely exceeding 6.4°C. December and February are only slightly warmer. The warmest weather arrives in the summer months, reaching its peak in August. At this time, the average temperature is a comfortable 18.8°C, with daytime highs averaging 23.1°C and nightly lows around 14.5°C. July is also very warm, with similar figures.

Summer in Arnhem is generally pleasantly warm rather than exhaustingly hot. Average maximum temperatures in June, July, and August range between 22-23°C, which creates excellent conditions for walking and outdoor activities. Winters, by contrast, are cool and mild, but not freezing. Average minimum temperatures in December, January, and February remain above zero, around 2-3°C, while during the day the air warms up to 6-8°C. Diurnal temperature fluctuations are most noticeable from April to September, when the difference between daytime highs and nightly lows can reach 8-9.5°C. In winter months, this difference narrows to 4-6°C, indicating more stable temperatures throughout the day.

In Arnhem, precipitation is distributed fairly evenly throughout the year, and there is no clearly defined rainy or dry season. A small amount of precipitation falls every month, averaging 2 to 3 mm. This means that heavy downpours are not typical for this region; instead, you should expect frequent but not too intense precipitation.

Despite the small total amount, rainy days in Arnhem are a regular occurrence. The highest number of days with precipitation occurs in December, with an average of 16. Slightly fewer, but still frequent, rains occur in January and March (15 days each). The "driest" month in terms of the number of rainy days is June, when precipitation is recorded for an average of 11 days. In other months, the number of rainy days fluctuates between 12 and 14, highlighting the need to be prepared for rain almost any time of the year.

The nature of precipitation in Arnhem is predominantly light or moderate rain, sometimes in the form of drizzle, which explains the low rainfall in millimeters despite the relatively high frequency of rainy days. In the winter months, such as January, February, and December, when average temperatures are near zero, especially at night, rain can turn into sleet or ice pellets. However, lasting snow cover and heavy snowfalls are not typical for Arnhem.

When planning a trip to Arnhem, it is important to consider the changeable weather typical of the Netherlands. Regardless of the time of year, the key principle when packing should be layering. This will allow you to easily adapt to temperature changes throughout the day, especially considering that even in summer, evenings can be cool. Given that Arnhem has between 11 and 16 days of precipitation every month—even if the total amount is small—a light waterproof raincoat or jacket and a compact umbrella will be your indispensable companions. Also, don't forget comfortable shoes, preferably water-resistant, as you are sure to do a lot of walking around the city, exploring its streets and parks.

For a trip in winter (December to February), when average temperatures range from 2.2°C to 8.2°C, be sure to bring a warm jacket or coat, several sweaters or fleeces, a hat, scarf, and gloves. In spring (March-May) and autumn (September-November), the weather can be quite fickle: warm sunny days can give way to cool and rainy ones. During this period, you will need a transitional jacket, jumpers, long-sleeved T-shirts, and, of course, reliable rain protection. In summer (June-August), Arnhem is usually warm, with average temperatures around 17.7°C - 18.8°C and highs reaching 22-23°C. Pack light clothing such as T-shirts, shorts, skirts, or light trousers, but don't forget a light sweater, cardigan, or windbreaker for evening walks or in case of a cooler day. Sunscreen and a hat will also come in handy on sunny days, and even in summer, a compact umbrella or light raincoat won't be out of place due to the possibility of short-lived showers.
