On the average, daytime temperature varies from 2C to -8C in the winter. In the summer, the daytime temperatures could be anywhere from 17C to 20C. Rainfall happens all throughout the year with clouds almost perpetually hovering over Netherlands.
There are four distinct seasonal patterns, but because it is a compact area, the changes are not severely sharp in various provinces and cities.
Coastal regions such as the south provinces of Holland enjoy the mildest climate throughout the year as well as the lowest rainfall.
The coldest months of the year are January (with average temperatures of -1 C to 4 C) and February and the warmest months are July and August (with temperatures reaching up to 22C).
The wettest months are August and September where rainfall occurs across 18 days and the driest month is March.
January also has the highest number of days with frost on the ground (15 days). There is snow, rainfall and hail in Holland.
During fall and winter, unexpected climatic changes bring about gales and uncomfortable weather with humidity going up to 88% in December.
Holland also experiences foggy weather during the winter and during heavy spells of cold weather, the bodies of water such as the rivers and the canals freeze over.
In the spring, some short but heavy rain showers can also occur. During the summer, thunderstorms can also occur during the midday due to the higher temperatures.
Average rainfall in Holland is about 30.2 inches or 2.5 inches per month. Average annual relative humidity is 77.3%. Whilst there are fewer days of rainfall during the summer, they tend to be heavier.
Visitors to Holland usually come around the summer months of July to August, when the weather is agreeable for walking outdoors and exploring the natural beauty of Holland. This is the time of the year, however, when the cities are packed.
The spring months of April and May are also great times for a leisurely trip to the country, as it is the time of the year when the flowers are in full bloom and the parks are all exploding in colour. April is the season for daffodils and May is when the tulips bulbs are in bloom.
For winter sports enthusiasts, December and January are the best months to plan a winter wonderland tour of Holland. When the temperatures drop below freezing point for some time (which actually only happens in rare occurrences), the canals and rivers become perfect grounds for ice skating.
Because rainfall happens and is spread all throughout the year, rainwear is always a part of the required clothing when travelling to Holland.
