Belgium is a great destination for tourists, offering a wide range of cultural and historical attractions. In September, it's best to bring a waterproof jacket as the weather can be unpredictable.

How warm is it in Belgium during September?

The temperature reaches around 20℃ during the daytime in September, falling away to 12℃ at night. The UV index will be moderate at this time of year, so not something to worry about for the average person. However, if you're going to be outside for long periods it's worth wearing a broad spectrum SPF 30+ sunscreen and UV-blocking sunglasses. Remember that bright surfaces, such as water and sand increase UV exposure.

Does it rain in Belgium during September?

On average, there will be 3 rainy days during the month, amounting to 48.4mm in total. That's broadly comparable with the amount of rain we see in England during the summer months, and would be considered dry. There's a small chance that you'll catch a thunderstorm during your trip.
