How cold is the deep sea off California?

The temperature of the deep sea off the coast of California varies based on the exact location and depth, but it typically ranges between 32°F (0°C) and 41°F (5°C). The ocean floor in this region is largely covered by the Eastern Pacific Ocean, which is characterized by cold, dense water. As depth increases, the temperature generally drops, influenced by the influx of cold water from polar regions. Near the sea floor, the temperature may be very close to freezing, but it rarely reaches the freezing point due to the high pressure at those depths.
