See how the daily temperature reading compares to the long term average:

In the plot above, you can find the most recent temperature data written out in the top left corner, with the sampling date and Sea Surface Temperature (SST) in degrees Celsius and degrees Fahrenheit. This most recent data point is shown on the plot in pink. You can compare this to the average temperature of that given day since 1919 (shown with the dark blue line), to see if it is warmer (above the dark blue line) or colder (below the dark blue line) than the long-term average. You can also see sea surface temperature every day from the start of the present year by looking at the light blue dots. Any light blue dots below the dark blue line show that ocean temperature has been colder than average and any light blue dots above the dark blue line show that ocean temperature has been warmer than average.

Staff from Stanford University’s Hopkins Marine Station take daily temperature measurements from a beach on the north side of Point Cabrillo just north of their main laboratory buildings. Exposed to the northwest swell as it sweeps past Point Piños, this location is representative of coastal conditions on the south side of Monterey Bay.

Below are figures that we have modeled after the #ShowYourStripes Campaign (created by Ed Hawkins), to help us visualize how sea surface temperature has changed at Pacific Grove since 1919. The change in temperature is relative to the average temperature calculated between 1919-2023.

Below you can see a plot showing Monthly Sea Surface Temperature Averages from the Pacific Grove Shore Station, split up by decade, since 1970.
