Ask OSIDEQuestions
- Is it safe to swim in Oceanside after rain?
- Health officials recommend staying out of the ocean for at least 72 hours after significant rain. Runoff carries bacteria from streets and storm drains, and official postings can lag behind a storm.
- Where does OSIDE get Oceanside water quality data?
- From California Beach Watch and San Diego County's beach monitoring program (sdbeachinfo.com), which post advisories, warnings and closures based on water sampling.
- What's the difference between an advisory, a warning and a closure?
- An advisory means bacteria levels exceed state standards at a spot, so avoid contact near the posted area. A warning is broader, and a closure means the water is off-limits, usually because of a sewage spill.
