Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

High pressure will build across the region this week resulting in a
rapid warming trend with many lower desert communities exceeding
the 110 degree threshold both Thursday and Friday. Some cooling
is anticipated over the weekend as a weak low pressure system
passes north of the region. There are no signs of rainfall through
early next week.
Not much to observe on the goes-16 visible channel over arizona
today as clear skies abound. Temperatures across the lower desert
are currently in the 103 to 107 range this early afternoon and
should continue to warm a few more degrees through early evening.
High pressure aloft will continue to build across our area through
the rest of the week. The ensembles are pretty consistent showing h5
heights increasing to near 594-596 dm across central arizona with
the most anomalous heights just off the san diego coast. This
will mean that Thursday and Friday will see the hottest
temperatures with highs in the 110 degree neighborhood for the
phoenix area while heating even a few degrees warmer in blythe and
Decided to increase the coverage of the existing heat warning for
Thursday and Friday to include portions of the northwest and
southeast valley where daytime temperatures, when most people will
be active and most vulnerable to the heat, is forecasted to be
110 plus degrees by Friday. This is quite the warm up, nearly 30
degrees, from the extraordinary cooler temperatures last weekend.
While the heat risk tool is a major driver for excessive heat
products, more weight was given to the hot daytime temperatures,
the significant warm up, and the sake of spatial continuity to
justify the excessive heat warning and warrant the increase in
Regardless, the ridge will take a decent drubbing by a subtle
wave pushing across our north on Saturday. This will do well to
reduce atmospheric heights and allow temperatures to cool much
closer to seasonal normal values for the weekend. Once the trough
exits into the central plains, the ridge will rebuild over the
southwest and temperatures will rise again.
South-central arizona including kphx, kiwa, and ksdl and southeast
california southwest arizona including kipl and kblh:
no weather-related aviation weather concerns through the TAF period.
Strong high pressure at the sfc and aloft to keep skies mainly clear
and winds on the light side(10 kts or less) through the TAF period.
Wind directions to mainly follow typical diurnal trends at the
phoenix area TAF sites, remain mainly for a southeasterly direction
at kipl, and a southerly direction at kblh through Thursday.
Aviation discussion not updated for amended tafs.
Saturday through Wednesday:
low pressure passing well to the north with push temperatures back
to near-normal values this weekend. Another warming trend is then
expected early next week as high pressure builds across the desert
southwest. Minimum afternoon humidity values will fall into the 10-
20% range each day. Overnight recoveries will be poor to fair.
Occasionally gusty winds can be expected Saturday ahead of a weak
area of low pressure passing by to the north, but otherwise typical
afternoon upslope gustiness will be common during the period. There
are no signs of rain through the middle of next week.

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.
