Belgium - weather in June

In June, the first summer month, the climate in Belgium is generally cool and quite rainy.

The average daily temperature is 15 °C (59 °F) on the coast (see Ostend), and around 17 °C (63 °F) in the plain east of the coast (see Brussels, Antwerp), while it drops to 14 °C (57 °F) in the Ardennes (see Bastogne, Spa and Saint-Hubert), which are further from the sea and at around 500 meters (1,600 feet) above sea level.
In the coldest periods, which generally occur in the first part of the month, the night temperature can drop to around 5 °C (41 °F).
On the other hand, on the hottest days, generally in the second half of the month, the temperature can exceed 30 °C (86 °F).

The rainfall increases slightly compared to May, and is quite frequent. In the Ardennes they are a little more abundant, also because on sunny days, thunderstorms can break out in the afternoon and evening, more easily than in the plains and on the coast.

The sea is decidedly cold for swimming, as its temperature is 14 °C (57 °F).

Even though the sun in Belgium never shines very often, we are in the sunniest period of the year, which lasts until August.

During the month, the length of the days gradually increases until June 21, the summer solstice, which is the longest day of the year in the northern hemisphere. In June, the average day in Belgium is 16 and a half hours long.
