Trinidad Beach & Bay

BEACH:
Daily Sea Surface Temperature and Salinity measured since 1975
Sampling Location: surf zone on Trinidad State Beach 
Location Coordinates: 41° 03' 36.3" N, 124° 08' 56.4" W
 
BAY:
Daily Sea Surface Temperature measured since 1973
Sampling Location: middle of Trinidad Pier, lowering bucket with rope
Location Coordinates: 41° 03' 20.7" N, 124° 08' 49.8" W

Read this description to understand how to interpret the two plots above:

In the first plot above, you can find the most recent temperature data from the Trinidad Beach Shore Station 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 1975 (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. The second plot is the same, except it shows the sea surface temperatures from the Trinidad Bay Shore Station since 1973.


Here are the zoomed in versions of the two graphs above so you can see the last 30 days of beach and bay sea surface temperature:

Student lab technicians and staff from Cal Poly Humboldt Telonicher Marine Laboratory collect daily temperature and salinity samples from the northwest side of Trinidad State Beach which is located on the rocky headland between the Pacific Ocean and Trinidad Bay. Salinity samples are returned to Scripps once a month for analysis.

Except during periods of heavy runoff, salinity values from the coast and the bay are nearly identical. The student lab technicians also collect daily temperature measurements from the fishing pier on the lee or southeast side of the rocky headland between the Pacific Ocean and Trinidad Bay. Salinity samples are collected at this location if surf conditions are too rough for Trinidad Beach.
