Winter has arrived properly in Norway this week ❄️ After a few days of heavy snow it already feels like mid-season, so it’s time to look a bit further ahead.
I’ve built a small interactive tool to explore ECMWF seasonal snow forecasts for the Nordics:

Those late summer rains do make for a dramatic sky

For this years Research days I'll be talking about climate change in Reisa national park in northern Norway. It's a protected area that is expected to see dramatic warming in the coming century:

Rome on the other hand:
Starting from a very good baseline of exceptional summers, but a clear negative trend with hotter and more intense heatwaves detracting from the overall experience.

Now look at Berlin.
📈 GSI is trending up — summers are getting better.
Why?
More sunny spells
More swimming weather
– But too much heat is now a downside.
Hotter ≠ better, once you’re sweating through 35°C.

But how is the quality of summers varying over time?
In Bergen the GSI since 1980 is chaotic — some gems, some write-offs, and no clear trends.
But the most important factors are crystal clear:
☀️ How warm is it?
☀️ How sunny is it?

Let’s zoom in on southern Norway 🇳🇴
Bergen is doing okay (for Bergen).
Oslofjord? Better.
But check out Kristiansand to Arendal — it really pops on the GSI.
There’s a reason so many people from Oslo head there for summer holidays.

Here’s how Europe looks so far for summer 2025 (June + July):
Coastal Mediterranean regions score high ✅
Further north = tougher summers ❄️
But zoom in, and the variability is interesting. ⬇️

We've had a gloriously warm and sunny summer in Bergen this year. You really need this break in a city where you know the heavy rain is just around the corner.

🌡️ Not all hot nights are equal. We track “tropical nights” when temps never dip below 20 °C—but what if it’s already 20 °C at bedtime? I crunched ERA5 data for 5 European capitals. Let’s talk tropical 10 pm. 👇

Looking like a quite high risk of a marine heatwave in the northern aquaculture production zones this summer:
