The following table shows the grades for San Luis Obispo County beaches for 2018 to 2019. The data was separated into three categories. Data are assigned to the Summer Dry season when beach usage tends to be higher. The Winter Dry season is November to March and only includes times without rain. The Wet Weather data includes times with rainfall throughout the year. This is because stormwater runoff can transport pollutants such as bacteria into our coastal waters, impacting our beaches. In 2018 to 2019, SLO County beaches received very high grades.
