Tier I beaches will generally be sampled twice per week with a minimum of one sample per week. Tier II beaches will generally be sampled five times per thirty-day period with a minimum of one sample per week. Tier III beaches will be sampled a minimum of twice per 30-day period.

Swim Guide checks for the latest information daily during the monitoring season.
