warm waters

Balmy ocean currents

Warm waters are bodies of water at comfortable or elevated temperatures, whether naturally heated or artificially warmed.

The phrase often appears in travel contexts—tropical destinations, hot springs, or heated pools: We swam in the warm waters of the Caribbean.

Figuratively, warm waters can suggest comfort or safety, while its opposite, hot water, means trouble.
