Water temperature questions

Where does the HUMBOLDT BAY (North Spit) water temperature come from?

Water temperature, wind, and seas on this page come from the NOAA NDBC realtime feed for station HBYC1 (9418767 - North Spit, CA). That is the same buoy file the HUMBOLDT BAY (North Spit) harbor page already requests. This page does not add a separate CO-OPS water-temperature product.

How fresh is the buoy reading?

The page shows the observation time from the NDBC report and the time Boat or Nope retrieved the file. The realtime file is cached for about 2 minutes when fresh, and a recent copy can be reused for up to 30 minutes if NDBC is briefly unavailable.

Why might the beach feel different from this temperature?

A buoy can sit offshore of the harbor, and shallow water warms and cools faster than the sensor. The station name and distance, when Boat or Nope has one, say how far the reading is from the harbor.

What does a cold reading mean for boating?

Water under 60°F can cause cold shock if someone falls in. The note on this page is general context. It is not a life-jacket or wetsuit rule for your boat.
