Is it true that when it rains the Internet goes worse, why does that happen, and when it is very hot, and with the wind?

We are not talking about big catastrophes that cause the destruction of infrastructures, of course, but about the usual changes in the climate of each area that are repeated year after year.

Our Internet connection can be affected by bad weather with these considerations:

– Water from rain, and subsequent humidity, can affect subway cables, mainly copper ones, responsible for ADSL connections. While fiber ducts are designed to be water and weather resistant, most deployed ducts are not designed to be permanently underwater. This is an issue that has generated several studies, as climate change may flood areas and affect communications infrastructure in the near future.

– Fiber optic connections are much more resistant to infiltration, they are not affected.

– Rain drops can cause drops in signal coverage, which is why there is a worse connection when it rains.

– Heat is the enemy of everything electronic, so with big heat waves there can be failures in the infrastructure that gives us access to the Internet, from our router at home to the large machines at the other end. On the other hand, copper and fiber optic cables are not susceptible to cold, but extreme temperature variations can cause contractions and expansions of the ground, which can damage or tear subway cables.

– Strong wind can move antennas, break them or affect their operation, which is why it is always a source of problems. Trees can fall on power lines and debris can knock down satellite dishes.

Still, the main cause of slowdowns is not heat, wind or rain, but how we humans act when it happens. We stay at home more, sometimes working in home office mode, sometimes “feigning illness”… When it rains there are more people connected to the Internet in areas where we would not expect so many connections and that means that there is less to share among all.
