The cooler ocean current along the west coast also makes summer temperatures cooler on the west coast compared to the east coast. For example, Half Moon Bay at 37°N has no month with an average high above 67 °F (19 °C) and San Francisco often stays below 70 °F (21 °C) in summer, while Virginia Beach, VA , close to the same latitude, has ...
Coastal California is heavily influenced by east–west distances to the dominant cold California Current as well as microclimates.Due to hills and coast ranges having strong meteorological effects, summer and winter temperatures (other than occasional heat waves) are heavily moderated by ocean currents and fog with strong seasonal lags compared to interior valleys as little as 10 mi (16 km) away.
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
The California Coastal Commission is asking the public to photograph high tidal waters for its King Tides Project, a community-led effort to help the public understand the effect of rising sea ...
The California Channel Islands Marine Sanctuary has been moderately successful as shown in a ten-year study done by the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO). From years 2003–2013, the MPA network implemented caused fish species to increase in biomass in terms of both size, numbers, and weight per area.
The water stops rising, reaching a local maximum called high tide. Sea level falls over several hours, revealing the intertidal zone; ebb tide. Oscillating currents produced by tides are known as tidal streams or tidal currents. The moment that the tidal current ceases is called slack water or slack tide. The tide then reverses direction and is ...

On nautical charts, the top of the chart is always true north, rather than magnetic north, towards which a compass points. Most charts include a compass rose depicting the variation between magnetic and true north. However, the use of the Mercator projection has drawbacks. This projection shows the lines of longitude as parallel.
