Sunny summer day in Vienna: 30 degrees and bright sunshine!

A bright summer day in Vienna awaits us today, June 4th, 2025. The city shows itself at its friendliest side, with a fine mix of sun and clouds. In the morning it is already clear and pleasantly warm with temperatures around 25 degrees. During the morning the temperatures climb to up to 29 degrees, with the sky alternately revealing the sun. Things continue in a similar way in the afternoon, when we can look forward to highs of around 30 degrees before thicker clouds take over in the evening.

The wind is moderate to brisk from the south to southeast, with peaks around 29 km/h. However, it doesn't bring a little cooling down, as the temperatures hardly fall below 24 degrees later in the evening. Rain is unlikely today, with only a 10% chance. There could be some scattered light drizzle overnight, but the day is expected to remain dry. With such friendly weather, there are no warnings, but weather experts recommend a solid sunscreen to protect the skin from the high UV rays, as Kosmo reports.

UV radiation in view

UV radiation plays a central role, especially on days like these. The UV index was measured in Vienna today. Even if there is no current data, you can still get your bearings: A maximum UV index of 8 is expected at 8:00 a.m., while this drops to the minimum time at 4:00 p.m. The skb offers a helpful scale for classifying UV exposure:

• 0-2: Schwache UV-Belastung – keine besonderen Maßnahmen nötig.
• 3-5: Mäßige UV-Belastung – Schutz empfohlen, besonders für empfindliche Hauttypen.
• 6-7: Hohe UV-Belastung – Schutzmaßnahmen erforderlich.
• 8-10: Sehr hohe UV-Belastung – direkte Sonne meiden, Schutzkleidung tragen.
• 11+: Extreme UV-Belastung – höchste Schutzmaßnahmen nötig.

Since we are on the edge of the mid-summer temperature range, it is particularly advisable for readers with lighter skin to use a sun protection factor (SPF) of at least 30, as recommended by Wetter.com. It's smart to put on a hat and also wear sunglasses, especially if you plan to be outside for a long time. From 10 a.m. to 4 p.m. you should also avoid the midday sun to protect your skin.

The coming days

If you look at the weather forecast for the coming days, it will continue to be summery. For Thursday, temperatures of up to 32 degrees are forecast in the east and south, while changeable weather with rain showers and thunderstorms is expected in the west. It will remain mostly sunny on Friday and temperatures will remain friendly. So it's the ideal time to enjoy the sun and plan outdoor activities, as long as you take the necessary protection!

With these views, the Viennese are well prepared to make the most of the beautiful weather and enjoy the fresh breeze. No matter whether on the Danube Island, in the city park or with a coffee outdoors - tomorrow's temperatures invite you to unwind!
