Lake Worth Beach is a saltwater beach in Palm Beach County, Florida. Across 522 bacteria samples collected between 2021 and 2025 at nearby monitoring stations, it earns a Beach Safety Grade of B — Good.
About 3% of samples at Lake Worth Beach exceeded the EPA Beach Action Value of 104 CFU/100 mL for Enterococcus — the threshold at which water managers typically post a swimming advisory. In practice that means the safe-swimming limit was rarely crossed here over the monitored period. Bacteria samples rarely exceed the safe-swimming threshold.
The evidence behind this grade is deep for a beach page: 522 results from 9 monitoring stations, spanning 2021 to 2025. Enough sampling, from enough places, over enough seasons that one bad week can't drive the letter.
In the most recent full reporting year, Lake Worth Beach was under a swimming advisory for about 0.6% of its monitored beach days — a useful gauge of how often problems recur here beyond any single sample.
