Lake Como in Lombardy, Northern Italy, is not ideal for swimming because it is a lake with deep areas, plus moss settles along the shore. Even though not the best, there are sections along the 47 km stretch of the lake where swimming is possible.

This article will discover the safe places along Lake Como where swimming is possible, any dangers that individuals could encounter while swimming in the lake, what lies beneath the lake, and any noteworthy facts relating to the lake.

Note the Best Time to Swim in Lake Como

The lake is located in the basin of the Alpine. The water temperature is cold. A drastic temperature change after prolonged sun exposure could be detrimental. The optimum time of the year to enjoy the waters of Lake Como is between March and November.

Many crowd the beaches along Lake Como, specifically during July and August. The months that are considered the best for swimming. Privacy on the beaches is practically impossible, as people try to hide from the heat. However, this does not mean you cannot enjoy the atmosphere.

Let’s comprehend Lake Como’s average weather and temperature using the following table to ease the selection of the best month to drop in Lake Como.

Can You Swim In Lake Como In Winter?

Yes, visiting Lake Como in winter – from December to February can make your trip less expensive than in the prime months. Still, I would not suggest you swim during this time because the temperatures can reach as low as 3 degrees celsius, which is not much of a pleasant experience. However, because Lake Como never freezes, you can still swim in it if you’re not faint-hearted.

Instead of swimming, you can taste local food – Pizzoccheri, Risotto Alla, Sciatt, Pesce Persico, and Milanese can kickstart your unforgettable experience. For an avid skier or snowboarder, places like Bormio, Lecco, Livigno, Madesimo, Piani Di Bobbio, Livigno, and the Alps of Engadin can engage you for a whole day of snow experience, and these places are also an easy reach from Lake Como town.

In winter, more aesthetic travelers can benefit from the less crowded lake Como to talk with locals and book restaurants without worrying about seat availability; spa hotels and Lake Como lights are another level – you can’t miss it!

Pollution in Lake Como (Read Before Drinking & Bathing in Como)

Understanding the pollution in Lake Como can be done using many techniques; in the past, none of these practices were imposed on the lake, but Goletta dei Laghi is actively measuring the levels of bacteria and microplastic in lake Como. Lake Como is well under safety as of 2021, 2019, and 2018.

For reference, Lake Como counted an average of 28,500 microplastic particles per cubic kilometer. However, on some parts of lake Como – between Dervio of Lecco and San Siro on the Como side counted up to 500,000 particles per cubic kilometer.

After seeing the increasing concern about plastic in the lake, the Italian Ministry of the Environment started the ‘Plastic Free Challenge’ initiative in 2018 to raise awareness, which Como has followed well. For example, Lido in Faggeto Lario and the bars here are well running themselves without single-use plastic (IMO, banning single-use plastic should give higher priority than banning multi-use plastic for significant impact)

After all my research, I can conclude that Goletta dei Laghi’s annual checks associated with Legambiente on both plastic waste and the biological side will continue their checks and actively share their data with local and national administrative entities.

They will work upon the data and gives tourist a third-party assurance that lake Como is safe for swimmers.

According to a Como Newsletter, 99% of public beaches on Lake Como are safe to swim. The numbers are accurate because the water quality is checked every month from April to the end of October (swimming is more advisable between these two months).

However, not all public beaches can gain the trust quickly because, after the analysis done on eighteen beaches on lake Como side from Griante on the west bank to the Como itself.

The Spiaggia Rivabella Crotto, Lezzeno was reported to be close in 2017 due to high levels of pollutants, though it is open now as figures are reasonable.

One primary concern for Lake Como in the past was DDT (a pesticide) and PCBs (used in electronic devices). Both are considered toxic chemicals, can exist for a long time, and accumulate in the food chain. The research has been put together to examine the levels of PCBs and DDT, where researchers took samples and cores in 2009. The cores serve as a medium for researchers to construct the timeline for lake Como’s last 20-25 years.

It was found that the core samples showed a gradual decline in the PCBs between 1970 to 2009; it is a combined total of 200 nanograms drop per gram of dry sediment over those years.

However, researchers noticed a noticeably increment in around 2000-2002 where the PCBs were close to 300 ng/d d.w, which may be due to the contents traveling with three floods. On the other side, levels of DDT never showed a decline. Instead, it remains constant over time.

Due to the findings in all studies, It is highly advisable to check this government website to know whether a particular place is safe to swim, bathe, or drink near Lake Como. To do this, follow these steps:

  1. Install Google translator if you want this Italian page in English
  2. Click to Menu (3 lines)
  3. Click on Thematic Areas, and from the dropdown, select bathing for swimming or drinking if you want to know whether the water in any commune near Lake Como is safe to drink.
  4. There, type the name of Comune (Village, resort, and any other notable locality) like Domaso.
  5. The Map will zoom in to select the locality, and the highlighted part of the river or lake will address the pollution and safety of bathing or drinking water.
  6. Please see the legend on that same page where different colors mean different things; note that a particular river or lake may be closed due to other reasons than pollution, as stated in the legend.
  7. Now zoom in enough to take note of the place. In Domaso’s example, Camping Gardenia, Gera Lario, and La Punta are safe swimming. However, check one more time on the website provided for frequent information.
