Sunshine Continues Into the Weekend
Looking ahead to Thursday, the sun is making a full comeback. Clear skies dominate, with temperatures once again reaching a pleasant high of 19°C.

Thursday night continues the clear streak with a low of 7°C, setting the stage for a nearly identical forecast on Friday, where we’ll see more sunshine and a high of 19°C. Friday night dips down to +3°C, so maybe keep that extra blanket handy.
What to Wear?
With highs nearing 19°C and a breeze tagging along, today is perfect for layering. A light jacket or hoodie will keep you cozy in the shade or early morning, and sunglasses are a must with that high UV index. Footwear? Think comfy sneakers — ideal for sidewalk strolling or a post-lunch park visit.
