Season follows Morro Bay & Port San Luis: No month stands out; the water ranges 7–13 °C with the time of year, and fast-changing weather decides which days the boat sites can be dived.

Know before you go

  • Water of 7–13 °C (45–55 °F) depending on the time of year; extra thermal protection might be needed.
  • Weather along the Central Coast can change very quickly and should be a top concern.
  • A large security zone surrounds the Diablo nuclear power plant on this coast; boats must stay out of it.
