There’s a general rain advisory in effect right now for all of San Diego County’s coastal waters. Please be advised to not go into the ocean waters of OB and the other beach areas due to high levels of bacteria from urban runoff. Especially the Dog Beach area since it’s the mouth of the San Diego River. This applies to dogs too. And it’s in effect for Mission Bay and San Diego Bay
This is from the County’s Department of Environmental Health and they say surfing, swimming and diving should be avoided for 72 hours following rain. The most rain fell November 20th, Wednesday – 48 hours ago.
Here’s the official announcement of the advisory, from their water quality website:
The Department of Environmental Health has issued a GENERAL RAIN ADVISORY for the coastal waters of San Diego County due to levels of contamination by urban runoff following rain. Swimmers, surfers, and other ocean users are warned that levels of bacteria can rise significantly in ocean waters, especially near storm drains, creeks, rivers, and lagoon outlets that discharge urban runoff. Activities such as swimming, surfing and diving should be avoided for 72 hours following rain. The most recent rain event occurred November 20, 2019.
The GENERAL RAIN ADVISORY for urban runoff contamination applies to beaches from San Onofre State Beach south to Border Field, including Mission Bay and San Diego Bay. While many coastal outlets are posted with permanent metal warning signs, additional temporary signs are not posted for General Advisories.
General (rain) advisories are issued when rainfall equal to or greater than 0.20 inch is received in coastal or valley areas of San Diego County. This can lead to elevated bacterial levels in ocean and bay water, especially those located adjacent to storm drains, creeks, rivers, and lagoon outlets. The Department of Environmental Health (DEH) advises beach users to avoid contact with ocean and bay water for a period of 72 hours after rainfall ends. Signage is not posted for general advisories.
