Brussels Weather Today

Live rain radar, current conditions, an hour-by-hour outlook and a seven-day forecast for Brussels, with original writing about the city's climate from The Daily Brussels.

Today's briefing

Brussels is looking lovely today with a high of 28 degrees and virtually no chance of rain, though the UV index is sitting at 7 so you'll want to slip on some sunscreen if you're heading out. With a gentle 15 kilometre per hour breeze and a low of 16 degrees tonight, it's a beautiful day to explore one of the city's parks or take a stroll through a local market without worrying about an umbrella. Saturday will hold steady at 28 degrees and dry as well, making it perfect for lingering over a coffee at an outdoor café, though Sunday will cool to 26 degrees with a small chance of rain creeping in. Either way, grab a light layer for the evenings when temperatures dip, and make the most of this gorgeous stretch of weather while it lasts.

Brussels weather, explained

How to read the Brussels forecast

A good forecast is really three views at once. The current panel tells you what it feels like outside right now, which is what matters before you head out the door. The hourly strip is for planning the next part of your day: when the rain band arrives, when the wind picks up, when it is warm enough to walk. The seven-day outlook is for the week ahead, and it is most reliable in the first three or four days. Read it from the top down and you will almost always have what you need for Brussels.

What the UV index actually means

The UV index rates the strength of the sun's ultraviolet radiation on a simple scale. Below 3 is low and you can be outside safely without protection. From 3 to 7 is moderate to high, the point at which sunburn becomes likely within an hour, so a hat and sunscreen earn their keep. Above 8 is very high to extreme, and skin can burn in minutes around the middle of the day. The index peaks at solar noon, not at the hottest part of the afternoon, so the safest habit is to check the number rather than judge by the temperature.

Why the overnight low matters as much as the high

Daytime maximums get the headlines, but the overnight minimum shapes how the day actually feels. A cold night means a slow, crisp start and, on clear evenings, the chance of fog or frost before dawn. A mild night means the warmth carries over and the morning is comfortable from the outset. Clear skies let heat escape and push the low down; cloud cover traps it and keeps the night warmer. That is why two days with the same maximum can feel completely different depending on the night that came before.
