My heart rate won’t show up during a swim workout

I’ve check all of my settings to try and fix the issue, but I have everything right and it still won’t show my heart rate during a workout. Does the size of the watch have anything to do with it?

Apple Watch Series 7, watchOS 9

This is actually pretty normal. Contained in this link, is the following statement:


  • Pool Swim: When you start a workout, be sure to accurately set the pool length to help your Apple Watch measure laps and distance. GPS isn't used during a Pool Swim, and water might prevent a heart-rate measurement, but calories, laps, and distance will still be tracked using the built-in accelerometer.

You could try to strap the watch to your wrist tighter as what is likely causing this is water getting underneath the heart sensors on the underside of your watch.
