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.

Area Forecast Discussion National Weather Service Las Vegas NV 800 PM PST Sat Nov 28 2020
SYNOPSIS. Weak ridging will enhance over the region this weekend, increasing temperatures back to at or above seasonal averages. Breezy north winds will persist along the Colorado River Valley this weekend before increasing Tuesday night into Wednesday as a system skirts by to our east. Otherwise, sunny skies expected all week!
UPDATE. Another clear and cold night is in store tonight, though low temperatures should moderate a few degrees from this mornings chilly observations. Nonetheless, NBM lows last night were several degrees too warm, and current observations are running very near yesterdays temperatures at this time. Though it won't be quite as cold thanks to several degrees of warming below 850mb, still suspect NBM populated temps may be running a little warm tonight, so I undercut guidance 2-3 degrees for most areas.
Aside from the temps, the current forecast remains in great shape and no other updates are necessary tonight.
DISCUSSION. Today through Friday. Cold temperatures swept across the region this morning, with portions of the Las Vegas Valley experiencing their first freeze of the season. Henderson Airport dropped down to 32F, while Nellis Air Force Base bottomed out at 31F Our desert dwellers will be happy. this morning will be the coolest morning through the remainder of the forecast period. A ridge of high pressure will slowly enhance over the region through the weekend, bringing afternoon high temperatures back to 3-5 degrees above seasonal averages.
Monday, the driving feature for the remainder of the week will move into the Pacific Northwest. This feature will take the form of a cut off low pressure system through the start of the workweek before pushing southeastward through the CONUS. Meanwhile, the associated digging, positively-tilted trough will tighten gradients across the Desert Southwest, as the region becomes sandwiched between the trough to the east and the ridge to the west. Flow aloft will become northerly and heights will fall, resulting in enhanced northerly winds along the Colorado River Valley and cooler temperatures. Due to topographic enhancement, wind gusts will have the potential meet Wind Advisory criteria Tuesday evening through Wednesday evening along the lower Colorado River Valley. These breezy conditions coupled with low relative humidity values will increase fire danger as well. Holding off on issuing any wind-related products at this time, as the exact position of the aforementioned trough will be key. How strong will the winds blow? How much of a temperature drop should we expect? These questions should be answered over the next few days as models continue to resolve the strength, timing, and location of this system. That said, we continue to forecast bone dry conditions, with no precipitation chances in sight to close out the month of November.
Through the remainder of the work week into the weekend, gradients will lax, as the ridge of high pressure works to build back in over the area allowing temperatures to improve once again. The persistent northerly flow aloft will open the door for potential bursts of energy to ride through the region. This will result in continued breezy afternoons along the Colorado River Valley. Otherwise, sunny skies expected through the entire forecast period.
AVIATION. For McCarran . Winds this weekend will generally follow diurnal trends with an afternoon direction from the northeast and an overnight direction from the southwest, remaining below 6 kts. No operationally significant cloud cover expected through the TAF period.
For the rest of southern Nevada, northwest Arizona and southeast California . Light winds generally favoring diurnal trends expected across the region. The exception to this is the Colorado River Valley where elevated northerly winds with gusts 25-30 kts will continue this afternoon and set up once again tomorrow afternoon at KIFP. Enhanced northerly winds expected to impact KEED and KHII as well with gusts 15-25 kts. No operationally significant cloud cover expected through the TAF period.
SPOTTER INFORMATION STATEMENT. Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.

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.
