Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis Seasonably hot daytime temperatures will prevail into
early next week. Dry conditions will also occur through Friday
followed by isolated afternoon thunderstorms mainly east to south of
tucson Saturday through next Tuesday.
Discussion Ir satellite imagery and surface observations depict
clear skies across much of southeast arizona this evening. The
exception was across far southeast cochise county where some
convective debris cloudiness was noted associated with a decaying
mcs over east-central sonora mexico. Surface winds valid 8 pm mst
were wly nwly at 5-15 mph.
28 00z ktwc sounding total precip water value of 0.61 inch was down
0.30 inch versus just 12 hours ago. Dew points at lower elevations
valid 8 pm mst ranged from the mid 20s-lower 30s, and these temps
were 10-25 degrees lower versus 24 hours ago. The very dry regime
was also evident via water vapor satellite imagery, and was due to
wly nwly flow throughout the column.
Clear skies will prevail across much of the area the rest of
tonight, with any clouds of significance expected to be confined to
far southeastern sections. Several hrrr solutions and the univ of az
wrf-nam and wrf-gfs suggest that outflow from the decaying MCS may
produce a dew point jump later tonight, especially southeast of
tucson. Any lower level moisture of significance will quickly mix-
out Wednesday allowing for sunny skies across much of the area.
Please refer to the additional sections for further detail.
Aviation Valid thru 29 06z.
Clear skies or a few clouds around 15k ft agl especially southeast
of ktus into Wednesday evening. Surface wind Wednesday afternoon
wly nwly 10-20 kts with gusts to near 30 kts. Strongest speeds
northeast of ktus and particularly near ksad. Surface wind variable
in direction less than 12 kts at other times. Aviation discussion
not updated for TAF amendments.
Fire weather Dry conditions through Friday. Isolated afternoon
and evening thunderstorms are forecast to return this weekend into
early next week. The bulk of these thunderstorms will be east to
south of tucson. West to northwest winds at 10-15 mph Wednesday
and Thursday afternoons, with the strongest speeds northeast of|
tucson and especially in vicinity of safford. 20-foot winds will
then be mainly less than 15 mph Friday into early next week.
Prev discussion 210 pm mst Dry air continues to overspread the
area this afternoon as the sharp drying noted on all 3 goes-16 water
vapor channels is steadily marching eastward. Deep bl mixing has
allowed surface dewpoints to fall from the 40s and 50s this morning
into the upper 20s and lower 30s across a good portion of the
forecast area. Outside of a lone storm that formed shortly before
noon over the chiricahua mtns, skies have remained precip free
through 21z. That being said, there has been some CU development
over the mountains of santa cruz county where dewpoints remain
The forecast remains on track for the rest of the afternoon evening
hours with the continued advection of dry air into the area. Any
storms that develop from mid afternoon onward should be short lived
and dissipate shortly before sunset with the loss of daytime
heating. I will maintain the slight chance mention in the mountains
of far eastern arizona until 03z, but even these locations may end
up dry for the rest of the day.
The story for much of the next 5-6 days will be one of unfavorably
positioned high pressure aloft for widespread thunderstorm
development with the ridge axis located off the california coast.
The resultant westerly flow across the area is obviously far from
ideal for afternoon convection and it won't be until late this
weekend or early next week before we see the high center shift and
position itself over new mexico. In the meantime, a few afternoon cu
in the mountains are just about all that one can hope for in terms
of sensible weather. There is a generalized consensus that moisture
will return early next week once the high sets up to our east and
only at that point should we see a return to more typical monsoon
As for temperatures, above normal values both during the day and at
night will be the rule although nothing anywhere near as hot as what
was seen last week. Upper level heights and temperatures do not
support a return of those types of values at any point during the
Twc watches warnings advisories None.

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.
