Which Garmin Is Best for Swimming?

The best Garmin smartwatch for swimming depends on how and where you swim. For dedicated swimmers and triathletes, the Garmin Fenix 8 is the top choice thanks to its advanced swimming and multisport features, as well as highly accurate open-water tracking. If you're looking for a lighter, more sport-focused alternative that's equally suited to swimming and other activities, the Garmin Forerunner 970 is an excellent option. For recreational pool swimming, the Garmin Venu 4 offers the best balance of features and value.

Garmin smartwatches are specifically designed to track both pool and open-water swimming accurately, measuring metrics such as distance, pace, stroke type and heart rate.

Garmin for Swimming: What Should You Look For?

Swimming places unique demands on a smartwatch. Water, different movement patterns and the combination of technique and endurance all mean that not every smartwatch is equally suitable.

Pool vs Open-Water Swimming

In the pool, Garmin watches automatically detect your laps and stroke type. When swimming in open water, GPS accuracy becomes far more important, as there are no fixed reference points.

Swimming Metrics

Garmin watches can measure:

  • Distance
  • Pace per 100 metres
  • SWOLF score (swimming efficiency)
  • Stroke type
  • Rest intervals

Water Resistance

Every Garmin sports watch featured in this guide is suitable for swimming, although some models are better equipped for intensive training or open-water swimming than others.

Swimming and Multisport Training

Many Garmin users combine swimming with running and cycling. If that's you, it's worth considering a triathlon or multisport model such as the Fenix or Forerunner series. These watches offer advanced training analysis and automatic sport transitions.

The comparison below will help you choose the Garmin watch that best matches your swimming style.
