Marine Weather and Tides
San Diego, CA

Version 3.4
What's New / NOTES
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.

A low pressure system moving inland across california will continue
cooler than average weather through Saturday. The marine layer will
remain very deep with patchy night and morning drizzle west of the
mountains. From Sunday through Tuesday the weather will turn warmer
and the marine layer shallower as the trough moves east.

Discussion For extreme southwestern california including orange...

san diego... Western riverside and southwestern san bernardino

the cloud layer is much thinner and less uniform this morning
compared to yesterday, and the 8 am visible satellite image showed
breaks in the overcast west of the mountains. The marine layer was
still very deep though, around 5300 feet, and stratocumulus have
already formed in those areas that saw the early morning clearing.

Rain and drizzle this morning was confined to the foothills of the
sbd and ora county mountains. The crestline area in san bernardino
was the focus of the greatest precip this morning with 0.12" at
cable canyon and 0.11" at crestline ridge. Clouds will remain banked
up against the lower mountain slopes in this area into the
afternoon. Elsewhere west of the mountains, skies will be partly to
mostly cloudy, and sunny in the higher mountains and the deserts.

A deep trough over the west with a 565 dm cold core was centered
near sfo this morning. Shortwaves will round the base of this trough
through Saturday. The main impulse will track across socal Saturday
morning and that is when more areas of light rain or drizzle are
possible along and west of the mountains. The higher mtns and
deserts will remain generally sunny, but it will be windy in the
afternoon and evening when onshore pressure gradients approach 10
mb and support winds of 15-30 mph with gusts of 40-50 mph.

The trough moves inland Sunday with higher pressure building over
the southwest in the afternoon for better coastal clearing, a
shallowing marine layer, and a warmer day in all areas. This trend
will continue early next week with further warming and a shallower
marine layer Monday through Wednesday.

On Thursday and Friday the long range progs forecast a trough to
deepen along the west coast for cooler weather, a deeper marine
layer and gusty mountain and desert winds.

251530z..Coast valleys coastal mountain slopes... Low clouds with
bases mostly between 3500 and 4500 ft msl and mountain obscurations
will gradually scatter out by midday. Low clouds redeveloping this
evening with bases near 2500-3500 feet msl and tops growing to 6000
feet overnight. Patchy drizzle overnight with local CIGS down to
about 1800 feet. Scatter out Saturday most areas between 18-20z.

Mountain crests desert mountain slopes deserts... Mostly clear today
through Saturday with a few CU over mountain crests. West winds with
sfc gusts 25-35 kt will produce localized llws with mod uddfs over
the mountain crests, and in the passes through Saturday.

West northwest winds with a few gusts exceeding 20 knots are
expected in the outer waters through Saturday night, mainly during
afternoons and evenings. Otherwise, no hazardous marine weather is
expected Sunday through Tuesday.

A long-period south swell will continue to produce elevated surf and
strong rip currents through this evening. Highest surf is expected
in northern san diego county and orange county. Check the surf zone
forecast and the beach hazards statement for details.

Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
