Marine Weather and Tides
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.

Area Forecast Discussion National Weather Service Reno NV 148 PM PDT Thu Aug 6 2020
Near or slightly below average temperatures through Friday will be followed by some warming this weekend into early next week. Thunderstorm chances return Friday and continue each afternoon through next Tuesday, mainly near the Sierra through at least the weekend. Thunderstorm chances decrease with a possible cooling trend by the middle of next week.
No notable change to the forecast for the next week. Main forecast item of note will be the potential for isolated to locally scattered afternoon and evening thunderstorms in the Sierra out into portions of far western NV Friday through Monday or Tuesday. Read on for more details regarding temperatures, winds, and thunderstorms.
Temperatures to remain near to slightly below average through Friday as cooler air has filtered into the region with a weak baggy trough moving into California (the southern end of a stronger low over the Pacific Northwest). Highs will remain into the 80s for Sierra valleys, with 90s (near 100 west-central NV) for lower valleys, for the weekend into the first part of next week. A cool down (~4-8 degrees) is expected for the latter half of next week as another trough moves into the Pacific Northwest. While the exact strength and southern extent of the trough remains in question, it should only make a minimal temperatures difference for the region.
* WINDS/FIRE WEATHER:
Fairly typical zephyr breezes are expected today with gusts generally in the 20-30 mph range; locally critical fire weather conditions are possible for a couple hours early this evening. Afternoon and evening winds are expected to diminish some Friday through the weekend as thermal gradients relax between the Central Valley of California and the Great Basin.
Winds based on guidance from the NBM and ECMWF ensemble indicate another increase in breezes for the early to middle portion of next week as the aforementioned trough moves into the Northwest CONUS. This will bring an increase in concern for fire weather; however, right now it doesn't look more than a lower-end concern regarding wind/RH potential.
A few buildups are possible mid-afternoon through early evening in Mono County (most likely along or east of Hwy 395) and out into Mineral and southern Lyon counties, with a couple cumulus buildups also possible in Lassen County (east of Lassen Peak). Thunderstorm potential is low (~10%); however, it is not zero so keep an eye to the sky if you are in these areas. As far as strength, we do not expect any storms like the beast in northern Washoe County yesterday as forcing is weak.
Moving on to Friday through Sunday, storm chances increase some in and near the Sierra as weak flow aloft near the upper trough axis allows convection a better chance to build over higher terrain with daytime heating. The best shot for a few storm north of I-80 looks to be Friday as by the weekend the flow aloft and position of the weak trough axis shifts to favor areas farther south. Storm strength look to remain generally modest although a stronger storm or two is always possible if more favorable forcing is found via small-scale storm interactions (unpredictable). In any case, heavy rain will be a threat as storms are expected to move very little. This raises the concern for localized flooding, mainly in and near burn areas where runoff could be enhanced.
Early next week, the threat for thunderstorms spreads across more of the region (possibly father into western and west-central NV) as zephyr breezes, and possible focus for thunderstorms, increase in response to tightening thermal gradients between CA-NV. Storm strength could increase somewhat given better overall focus for storms. At first glance, heavy rain (storms still fairly slow- moving), pea to dime sized hail, and wind gusts over 50 mph are all possible. Also, the fire concern will increase as the coverage of lightning expands over more of the region. -Snyder
VFR conditions will prevail today with a few cumulus buildups this afternoon, mainly in the eastern Sierra and far western Mineral County between Highways 395 and 95. There is a small chance (~10%) late this afternoon for these cumulus buildups to develop into a thunderstorm. Winds today will be typical for summer with southwest to west breezes developing this afternoon (peak gusts 20-25 kts).
As we go into Friday and over the weekend, afternoon breezes are expected to relax (gusts ~15 kts or less). Thunderstorm chances increase, especially for the Sierra and far western NV south of Highway 50 and west of Highway 95. Still, thunderstorms are expected to remain fairly isolated east of the Sierra crest through the weekend. -Snyder/JCM

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.
