Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Update Updated air quality issues.
Synopsis Subtropical moisture will continue to flow from the
southeast during the next couple of days and will bring a chance
of thunderstorms to mainly the mountains and desert. Otherwise,
temperatures will continue warm with higher humidity over the
central california interior.
Discussion Latest satellite images have been showing some
subtropical moisture that has been moving from the southeast due
to the passing disturbance (also known as an easterly wave) over
southern california. Also, some mid-level and high clouds are over
the southern half of the forecast area, including kern, tulare,
and kings counties. Clouds will continue to move northwestward
over much of the region during the next few hours. However, some
clearing has occurred over eastern kern county, while lower level
moisture remains. So, instability has been sufficient for
isolated showers and thunderstorms that have developed over the
kern county desert and areas mainly to the south early this
afternoon so far. Expect more showers and thunderstorms to form
later this afternoon into this evening in these areas and over the
sierra nevada. Otherwise, smoke will continue to produce reduced
air quality and remain a health concern in some areas due to the
ferguson fire to the west of yosemite (see sfoaqahnx, or the air
quality ALERT issued by the sjv air pollution control district for
On Thursday, there is a renewed threat of afternoon and evening
thunderstorms over the higher terrain and desert as moisture will
remain over the region. A slight chance for showers and thunderstorms
is possible in the higher terrain along the west side of the san
joaquin valley, as shorter-term models hint on some instability
due to the presence of subtropical moisture circulating around the
high pressure system centered over the desert southwest and a low
pressure system off the coast of baja california. However,
confidence in this scenario is pretty low, while overall medium in
terms of the forecast. Otherwise, temperatures will remain|
several degrees above average, though quite typical through at
least the remainder of the week. Some low level moisture will
increase over much of region, including into the central valley,
and it might feel a bit muggy at times on Thursday and Friday,
while some mid-level clouds will pass over central california at
times. Models remain in general agreement that shower and
thunderstorm coverage will decrease a little on Friday and remain
over the higher elevations of the sierra nevada.
Showers and thunderstorms are expected to continue mainly near and
along the sierra nevada crest over the weekend, while temperatures
moderate slightly. However, high pressure will rebuild early next
week over much of california and the southwestern u.S., so that
temperatures will warm back up to at least several degrees above
average. Shower and thunderstorm activity remains a possibility in
the afternoons and evenings along the sierra nevada crest next
Areas of MVFR visibility in smoke will continue in the vicinity of
the ferguson fire in mariposa county for at least the next 24 hours.
Isolated thunderstorms are expected over the sierra nevada, as well
as the kern county mountains and desert through 04z Thursday and
again after 19z Thursday. Otherwise,VFR conditions will prevail
over the central california interior during the next 24 hours.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
