Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Light winds with limited valley ventilation will continue for most areas through Saturday afternoon. Weak low pressure will bring scattered very light snow showers Saturday night into Sunday, mainly north of Susanville and Gerlach, along with brisk northerly winds into Monday. No significant precipitation is expected next week.
No significant change to the forecast through the weekend.
Through tomorrow afternoon, stagnant conditions will persist with valley inversions and insufficient mixing (winds aloft too weak) to clear out valley air. This has resulted in areas of moderate air quality/haze in the Reno-Sparks area and around Truckee today. With little changing atmospherically, areas of somewhat degraded air quality are likely to persist through tomorrow afternoon.
Saturday night into Sunday, a modest disturbance will split off from the main Pacific flow (well off the West Coast) and move over northeast CA and western NV. This will bring colder and windier conditions to higher elevations; however, for valleys it looks like mostly a wash for highs as inverted valley temperatures Saturday wind up mixing up to similar readings (within 5 degrees) for Sunday There could be a brief a westerly wind increase (gusts ~20-35 mph) for valleys near the system's frontal boundary Saturday night or early Sunday, especially in eastern CA into far western NV.
As far as precipitation Saturday night into Sunday, chances remain for a very minor (less than 0.5") snowfall north of Susanville and Gerlach with scattered snow showers. Can't rule out slick roads/travel impacts over Cedar Pass or for higher elevation roads in Lassen and northern Washoe counties. -Snyder
LONG TERM. Monday through next week .
A closed low will develop across the Nevada/Utah border Sunday into Monday which will retrograde back offshore by Tuesday. What does mean in terms of our weather across western Nevada and the northern Sierra? It'll mean mainly seeing gusty east winds developing across the Sierra ridgetops beginning Sunday evening and peaking through the day on Monday. Could be a high wind issue for ski areas especially along Sierra crest with gusts reaching near 100 mph right along the mountain tops. Some of these winds could surface into the Sierra valleys but more so looking in the 30-40 mph range at this time. Boating hazards from rough water will be possible on Lake Tahoe, especially along the west shore.
In terms of precipitation with this low, besides having a very slight chance for a stray shower along the eastern Sierra, the majority of the region will remain dry. For the remainder of the week, temperatures look to remain within about 5 degrees or so of seasonal averages with dry conditions remaining until at least the start of next weekend. While quite a few ensemble suites do maintain high pressure through next weekend, there could some retrograding of the ridge to allow a weaker slider type trough to penetrate inland but still not a favorable setup to see any significant precipitation.

VFR with mainly light (less than 10 kt) winds and some passing higher clouds are expected through Saturday evening for eastern CA and western NV terminals. Valley inversions are allowing pollutants to build up a bit so some degradation of slantwise visibility is possible through Saturday afternoon.
Fairly weak low pressure is still on track to move into northeast CA and western NV Saturday night and Sunday. Scattered light snow showers are possible early Sunday from KSVE-Gerlach northward to the Oregon border but measurable precip chances for the main terminals remain slim (below 10%). North to northeast winds increase a bit for Sunday-Monday, with potentially stronger ridge gusts producing areas of increased turbulence Monday into Tuesday morning over and west of the Sierra crest. -Snyder/MJD

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
