Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

area forecast discussion
national weather service san francisco bay area
444 am pdt Fri mar 22 2019
Synopsis A frontal boundary will move from northwest to
southeast across the region today resulting in widespread rainfall
through tonight. Mainly dry conditions develop over the weekend
with unsettled weather likely to return during at least the first
half of next week.
Discussion As of 03:11 am pdt Friday... A modest plume of
atmospheric moisture is forecast to advect inland across the
region today ahead of an approaching frontal boundary. Light rain
will develop first over coastal areas from the santa cruz
mountains northward into the north bay through the morning. As the
front pushes inland from the northwest, rain will become more
widespread over the san francisco bay area this afternoon before
shifting southward into the central coast during the evening
hours. Rainfall will generally be light to occasionally moderate
with breezy southerly winds ahead of and along the frontal
boundary. In wake of the front's passage, northerly winds will
develop and precipitation will diminish from north to south
through the night. A few lingering showers may persist into early
Saturday morning, yet much of the region will dry out shortly
after sunrise. Rainfall amounts are forecast to range from 0.25"
to 0.75" for most urban areas while the coastal ranges and north
bay mountains hills could see upwards of 1.50".
Seasonably cool temperatures are expected on Saturday with
daytime temperatures in the upper 60s to lower 60s as brisk
northwest winds prevail. Winds relax some on Sunday and turn
southerly head of the next weather system to approach the region.
This will lead to slightly warmer temperatures during the day
After the brief dry period this weekend, unsettled weather
conditions return late Sunday with periods of rain expected
through at least the first half next week. The models generally
agree with the first system pushing across the region Sunday night
into Monday followed by a 12 to 24 hour break in between weather
systems. Additional widespread rainfall is expected from late
Tuesday into Wednesday with the potential for subsequent systems
to move across the region through late week. The details regarding
timing and location of greatest rainfall remain difficult to pin|
down at this time given differences model output. Regardless, the
ensembles point toward an unsettled pattern with periods of
rainfall through much of next week.
Aviation As of 4:44 am pdt Friday... For 12z tafs. With the
exception of sts,VFR conditions were observed at the TAF sites as
of the 12z TAF publication time. As the morning progresses,
ceilings are forecast to drop to MVFR levels as rain shower
chances increase with the next approaching system. In addition to
the lowering ceilings and rain, southerly winds are forecast for
much of the day throughout the bay area. Rain will become more
widespread in the afternoon evening hours the front approaches.
Vicinity of ksfo...VFR conditions were observed as of the 12z taf
issuance, but expect lowering ceilings to MVFR levels over the
next several hours as the next system approaches, initially
accompanied with light rain showers. There will likely be a short
break in the rain late in the morning, but rain will return in the
afternoon. Southeasterly winds are forecast to prevail through the
day, becoming gusty at times this afternoon. Winds will eventually
become west to northwest overnight.
Sfo bridge approach... Similar to ksfo.
Monterey bay terminals...VFR MVFR conditions are expected as an
approaching system brings increasing clouds to both mry and sns
with southerly winds through the day.
Marine As of 03:11 am pdt Friday... Southerly winds will
increase over the waters through the day as a frontal system
moves across the coastal waters. Winds will become northwesterly
overnight and into Saturday behind the frontal passage. A
moderate long-period swell will arrive over the next 24 hours and
continue through Saturday, bringing hazardous seas to mariners in

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 L-36.com 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.
