Manual Shore Stations

Latitude:35° 9.60’ N
Longitude:120° 45.60’ W
January 1972 to June 2001
Measurements Taken
Port San Luis / Avila Shore Station

This tide gauge station is located on the old fishing pier in the northwest corner of the harbor. Moved from the previous site on Avila recreational pier in 1972, the present location is less subject to storm damage. Temperature is about 0.1C warmer at the new site. The new automated temperature system, which records one reading each hour, became fully operational in September of 1993 and manual data collection was subsequently discontinued several months later. To be comparative with the other shore stations providing a single daily reading, these hourly values were averaged over the 24-hour period into one daily mean temperature. Analysis shows that this value is somewhat cooler than the historical data set.
