Band used
21 to 32

Of the twelve months measured over twenty years in Miami, 12 fall inside the 21 to 32 degree band used here for Swimming. The longest run of them is January, February, March, April, May, June, July, August, September, October, November and December.

The band is only about the air: below 21 degrees of monthly mean, getting out of the water is the unpleasant part. The water temperature is what would really decide it and this source does not hold it.

The warmest month is August, at a mean of 29 degrees. The coldest is January, at 21.2.

The figures are monthly means for Miami over 2001-2020, read from one satellite reanalysis cell. The 21 to 32 degree band is a stated convention rather than a measurement, and it is the only judgement on this page.

This page says when, not where. It names no route, trail, pool, gym or club, because the dataset that holds those is not built here. There is no water temperature, no gradient and no surface in this source either, so a comfortable month is about the air and nothing else.

Questions

When is the best time for swimming in Miami?

The longest comfortable run is January, February, March, April, May, June, July, August, September, October, November and December, on the 21 to 32 degree band this page states. The table gives every month, so a different band can be read off it.

Does this list routes?

No. It says which months are comfortable and nothing about where to go. Routes, trails and pools need a dataset this programme has not been able to build, and inventing a route list would be worse than leaving it out.

Where do the temperatures come from?

From monthly climate normals published by NASA POWER, averaged over twenty years and read at one grid cell for the city. They are means for the whole day and month, not daytime highs.
