Wells – Status and forecast. And what happened 2023?

Last year, there were major concerns about the summer with climate change and the El Ninjo weather phenomenon.
2023 was the hottest year on Earth so far. Sweden was record dry for a long time, but then everything changed in July.
What happened to groundwater levels in 2023 – and what does the situation look like for 2024?

We summarize data from SGU and some of the wells connected to Aqvify.
If you want to monitor your own well – order now to get a baseline for the summer.

2023 – dry early summer… and then really wet

Last year’s spring and summer in Sweden was volatile, to say the least. This is how SMHI summarizes in its article Summer 2023 – The summer that changed character:
The summer of 2023 will go down in history as the summer that changed character. Early vacationers will remember a dry summer, in the south with the risk of water shortages and extensive fire bans, while those who saved their summer vacation had to celebrate it in extensive shower activity that at times affected the whole of Sweden. There were also high flows and flooding. Overall, the summer of 2023 saw record rainfall in Örebro, Västerås and Delsbo, among other places.

This is what it looked like for some of the several hundred well owners who have their wells connected with Aqvify:

The image compares groundwater levels over the years. You can see how quickly the levels dropped in the spring and dry early summer of 2023 – and it looked like it could be really bad!!!
Then came the rain and floods that “saved” the groundwater supply, while destroying a number of basements and vacations… 😥

The lowest levels were measured more than a month earlier in 2023, compared to what we have seen in previous years (red arrows).

Forecast for summer 2024

The first quarter of the year has hardly been dry and hot. When will the long-awaited spring actually arrive?!?!!
The Geological Survey of Sweden (SGU) is the authority that keeps track of groundwater – and publishes very good information on Groundwater.

The image below shows the deviation as a comparison between current groundwater levels and levels during the corresponding week in 1961-2023, as well as the future development of groundwater levels for the next 60 days under different weather scenarios.

SGU Grundvatten: Groundwater deviation – current and forecast 60 days (March 26, 2024)

Groundwater reservoirs in Sweden are currently at normal or high levels across much of the country. The outlook for groundwater levels in April and June is more positive than last year, assuming normal rainfall. However, areas like Gotland and inner Småland may face challenges if it gets drier, potentially leading to a difficult start to the summer.

The El Niño weather phenomenon might continue to affect us this year. Additionally, the past nine(!) years have been the warmest on record (TT Omni), with climate change causing both droughts and heavy rains.

In summary, our reservoirs are well-prepared for the upcoming season, but there’s a risk that Scandinavia, like other parts of Europe and the world, might experience increased heat and dryness. Predicting weather months in advance is a tough job for hydrogeologists and meteorologists..

We hope, in the Swedish way, for a “just right” summer.

On Grundvattenkollen.se you can follow the groundwater levels in wells used in holiday homes, communities and agriculture in different areas.
