My Ultra watch is constantly issuing loud noise warnings while cycling most often between 25km/h and 30km/h. Ironically, when going faster and the wind is louder, not a peep from the watch. It would expect it to be zapping my wrist with warnings at much higher speeds.
Thanks for the suggestion.
It has nothing to do with that. There is something wrong with the sensor/software detection in that you are riding tempo at 30km/h and it goes off. If you are moving much faster, the air resistance doubles as the speed increases, yet no alarm. The sound of the wind is much louder. With the amount of cycling I do and with all the pro riders going much faster than a mere mortal like me, they and I should be deaf by the time they are 40.
If it has something to do with the speed, then why doesn't the alarm go off when experiencing 30 to 40 km/h winds.
My supposition is the air pressure at the opening of the mic is exactly at 90 degrees to the direction of travel. If part of the cycling jersey I am wearing (like a long sleeve jersey) is over the mic, I do not experience this phenomenon. It seems to only happen if the mic is directly exposed to the oncoming air.

I started to use my new series 8 for cycling this week, experienced the same issue and I decided to disable the loud noise notifications. I wear my watch on the right wrist with the mic exposed directly to the air stream.
I was riding between 25-30 km/h with peaks of 45 km/h and I received like 3 notifications, but since I have the notifications disabled while doing workout I don't know exactly when I got them.
No, it is on the left wrist. They aren't actually using sound waves to detect the decibel levels but air pressure. One day I walked beside a water excavating pressure truck which has a huge vacuum on it and is louder than stink and the watch didn't say a thing. They have to be using some pressure algorithm because it makes no sense that at 23kph the alarm goes off and I am the only noise making object on the road.
I can't answer your questions. I'd recommend you reach out to Apple Support directly for help.

Guess you wear your watch either upside down or on your right wrist. I am left handed so I wear it on my right wrist and have the same issue
I've had the same problem but every time I ride my motorcycle - for the past 3 years. I'm going to look and see if the suggested article will advise on how to set for motorcycle riding.
