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 1924 (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.

City of Newport Beach lifeguards take daily temperature and surface salinity samples from the waters surrounding the Newport Pier, which is located about two miles from the mouth of the Santa Ana River. Analysis of these salinity samples indicates that they reflect oceanic conditions except during winter storms when the salinity is strongly affected by runoff from the river.

Starting in 1924, these data were recorded predominantly from the Balboa Pier, which is located just 1.7 miles southeast of the Newport Pier. The sampling location changed to Newport Pier in the mid-1950s. Daily temperature measurements from 1979 to 2012 were read from a fixed thermistor near the end of the pier. For the last several decades, however, the data has been collected almost exclusively from the Newport Pier. These sites are so similar that the data collected from either location are consistent with the long-term record

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 Newport Beach Pier since 1924. The change in temperature is relative to the average temperature calculated between 1924-2022.
