Swimming at any time of the day is better than not swimming at all. If you’re wondering when the best time to swim is, then you’re not alone.


There are quite a number of different studies that suggest that training in the late afternoon or early evening is the best time for most people. The reason for this has to do with muscle temperature, which reaches its peak around this time. Warmer muscles increase the metabolic processes and energy metabolism of the muscles.

This rise in muscle temperature can be explained by your biological clock. This internal mechanism determines your day-night rhythm and has a big influence on bodily functions that fluctuate over the day like body temperature, heart rate and metabolism.

You can achieve a similar effect by warming up properly before starting a swim workout. Unfortunately, it’s not quite that simple to determine the best time of day to train. Stress, work, eating habits and sleep influence your biorhythm, as does your mental state. As a result, it really depends on your life circumstances and your personal preferences that will determine what time of day is best for you.

Check out what happens to your body when you swim:

Swimming In The Morning


  • Swimming in the morning leaves you energized for the rest of the day.
  • Some pools are practically empty this time of day, so you won’t have to wait to deal with crowded lanes.
  • In summer, it is much easier to train in the morning due to the earlier sunrise time.
  • Studies have shown that your testosterone level is at its highest in the morning. This can be really helpful, especially for doing high-intensity workouts.


  • After waking up, your joints and muscles are still tight and stiff. An extensive warm-up is necessary to get your body ready to exercise.
  • Generally, people tend to lack energy in the morning. It’ll take a little while to get your metabolism and cardiovascular system revved up.
  • If you want to swim before work, you should go to bed earlier the night before to ensure that you get enough sleep.
  • If you’re not a morning person, you’re going to find it pretty difficult to work out in the morning.

Swim At Lunchtime

Lunch swims or other short workouts at lunchtime are quite popular.


  • You can use your lunch break at work to swim.
  • If you had a stressful morning, a lunch workout can give you renewed energy for the rest of the work day.


  • The big problem for many people is the time factor. If your lunch break is short, then you won’t have time to squeeze in a swim.
  • If you’re not near a pool, this can be difficult.

Swimming In The Evening

In the late afternoon or early evening, your body is running at full speed.


  • Your muscle temperature reaches its peak, thus enhancing your performance.
  • You can swim harder because you have enough time afterwards to recover.
  • It’s a great way to relieve work stress, so you can enjoy a relaxing evening.


  • People often lack motivation after a strenuous day at work.
  • Intense workouts shortly before bed can make it hard to fall asleep. Your autonomic nervous system needs time to return to normal. That’s why you should finish your workout at least one or two hours before going to bed.

The best way to find out what time of day is best for you is to try out different training times and then decide which one is perfect for your schedule.
