The climate in Belgium is called temperate. Or more precisely: a temperate maritime climate, which occurs mainly along the Atlantic coast of Europe and is strongly influenced by the Gulf Stream.
The temperate maritime climate occurs between the polar and subtropical climates. Because of this location, it is alternately influenced by both climate zones. The proximity of the sea exerts a particularly strong influence. Due to their vastness (seas and oceans cover about 70% of the globe) and their thermal inertia (they take a long time to warm up or cool down), the stored heat is slowly released to the atmosphere (by evaporation and conduction). This explains why this climate has few extremes and is generally characterised by relatively mild winters and fresh, humid summers.
Denmark is located in the large part of north-western Europe that has a temperate maritime climate. Because of this, Denmark has four seasons, each with their own weather patterns. The winters are fairly mild and can have some vicious winter days. Spring and autumn are fickle, with both cool days and pleasantly warm days possible. The summer is moderate on average. What you will notice in Denmark is that both sunny hot summers and changeable cooler summers can occur. If you take all the climate statistics into consideration, the summer is the best time to travel to Denmark. The most pleasant travel period is from the end of May to the beginning of September. If you had to choose, we would prefer July and August for almost all of our trips. That coincides with the Dutch summer holidays, which makes Denmark a travel destination that is mainly visited during the summer holidays.
The interior state of Switzerland is known for its neutrality within Europe, its relatively high prices, its high standard of living and its beautiful landscapes. The mountain landscapes of Switzerland are among the most beautiful in the world. It is not without reason that the country can count on tourists all year round who come mainly to enjoy nature in all its diversity. The weather is an important factor. It is therefore a good idea to find out in advance what kind of weather you can expect in Switzerland during certain travel periods.
When travelling to Poland, you will have to deal with a continental climate. Basically, it resembles the weather in the Netherlands, however, it is on average drier and there are more sharp edges to the seasons. This means that the winter months are more wintry than in the Netherlands and the summer months have more contrasts. The best time to travel to Poland is in summer. As late spring can be quite pleasant and early autumn has enough warm days, you can consider the period mid-May to mid-September as the best time to travel to Poland. Daytime temperatures in summer are around the comfortable values of 22 to 27 degrees Celsius.
The Czech Republic, located in the centre of Europe, has a mix of almost flat lowlands, hilly landscapes and a number of mountains, which often serve as national borders. The climate of the Czech Republic is mainly a mix of a temperate maritime climate and a temperate continental climate. In the mountains, you will also find the tundra climate at higher altitudes. Because the Czech Republic is in Europe, there are four seasons which are almost equal to our seasons.
