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 1965 (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.

Personnel of the City of San Clemente Department of Marine Safety take daily temperature and salinity samples from the San Clemente pier. Salinity samples are returned to Scripps monthly for analysis by salinometer.

Prior to 1970, sampling for this area was conducted at Dana Point (1965-1970). Because the conditions are so similar, the long record for this area has been maintained.

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 the San Clemente Pier since 1965. The change in temperature is relative to the average temperature calculated between 1965-2022.
