Which specific holiday weekend frequently sees swimming cautions issued due to heavy preceding rainfall events?

Answer

Labor Day weekend

Public communications regarding swimming advisories often highlight specific correlations between periods of heavy, disruptive weather and upcoming major recreational periods. Reports frequently note that swimming cautions issued just before or during Labor Day weekend are directly attributed to significant heavy rains that occurred immediately prior to the holiday, which led to elevated bacterial counts resulting from the stormwater runoff overwhelming drainage systems.
