Data Analysis Availability

Both SST and Chlorophyll data are only updated during the week days, Monday to Friday excluding national and local public holidays (mainly Wellington).

No update is available during the holiday break between Christmas and the New Year (25 December to 2 January inclusive).

Normally, updated data will be on the web site about half past noon. The most recent Chlorophyll images will always be about 3 days old.
