One only has to go to the nearest community pool to realize that swimmers do not have any collective preferences on what time of the day they would like to swim.
There are several factors involved in making these decisions. The restrictions imposed by the daily schedule, ability to get up early in the morning and feel motivated enough to jump in the water which can be cold at times, and other factors such as traffic, early morning workplace commitments like meetings etc. It is also possible that some people prefer to jump in the pool after a long day’s work to get refreshed and rejuvenated.
Ideally the best time to get a good workout from swimming is during the morning well before the rush hour. Due to body’s circadian rhythm and higher energy and hormone levels in the morning, an aerobic exercise such as swimming can give a tremendous boost in a synchronized manner so that the whole day goes by in an ebullient manner.
However, there is also a strong physiological case for an evening swimming routine when the mind and body are very tired and a splash in cold water is just the right medicine for tired muscles.
Ideally if one has enough time, an intense swimming regimen in the morning ranging from 60-70 minutes and a relatively casual swimming regimen in the evening for 30-40 min should be adequate for overall mind body relaxation and conditioning for peak performance with tranquil mindset.
However, a lot of students in Universities and many young and middle aged athletes swim for several hours a day from morning to noon and this regimen is great for those who want to build a professional swimming career.
