Sea temperature
The water, measured and modelled
Measured at the farm, modelled for the bay and seen from space: up to ninety days back, with the model's forecast ahead.
Waiting for the next OCIMS model run; the last was on 21 September.
- Farm intake (five readings a day)
- Bay model, surface (OCIMS)
- Bay model, next 48 h· temporarily unavailable
- Satellite, daily (NOAA)
These measure different things. The farm reading is the seawater we pump through the farm; the model is a coastal ocean simulation for a point in the bay; the satellite is a 5 km pixel of the surface skin, a day or two behind. Differences of a degree or two between them are normal.
Farm readings here go back to 23 September 2026 and are added five times a day; the satellite series fills in as NOAA publishes.
