About Coastal Water Temperature Guide The water temperatures in the NODC Coastal Water Temperature Guide (CWTG) webpage tables are near-real time (recent) temperatures and climatological averages based on observations from NOAA/National Ocean Service (NOS) tide stations and NOAA/National Data Buoy Center (NDBC) buoys.These average water temperatures were computed from long-period records ranging from several years to several decades depending on how long observations have been taken at a given station. Although ocean conditions vary from year to year, water temperatures are less variable than air temperatures, so these averages can provide useful information for planning beach activities such as swimming or fishing. For the Gulf coast, only monthly averages are presented. Water temperatures vary more along the Atlantic and Pacific coasts of the United States, so for these stations two-week averages are presented from April through October. Clicking on the hyperlinked "Recent Temperatures" in the table will display time series plots of the last few hours of NOS Water Temperature data for the tide station, or will go to the NDBC Buoy Page for the location. Temperature tables (except Hawaii, Alaska, and Pacific Islands table) were originally created in the early 1980s by former NODC meteorologist Richard M. DeAngelis. Hawaii, Alaska, and Pacific Islands table values are based on NOAA/NOS publication "Surface Water Temperature and Density, Pacific Coast, North and South America & Pacific Ocean Islands." |
