Marine Weather and Tides
Hampton Beach, NH

Version 3.4
What's New / NOTES
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.

Synopsis
A cold front will slowly drop south through the region tonight
through Saturday and will stall south of new england Saturday
night. High pressure will build in from the northeast on Sunday
and will hold over the region Sunday night. High pressure will
shift east on Monday as a weak warm front approaches from the
west. A cold front will drop south through the region Monday
night. High pressure will build over the region Tuesday and will
push offshore south of new england Wednesday.

Near term until 6 am Saturday morning
Update 2... Temperatures still quite warm for almost 11 pm. Used
observations to tweak temperatures up. Also adjusted pops and
weather mostly in the the jackman to pittston farm area where
several rounds of showers and thunderstorms have been moving
through.

Update... Will issue a quick update. Have adjusted temperatures
and dew points to observations and have trimmed back pops except
for the northeast portion of the forecast area. No other
changes.

Previous discussion... Back door cold front currently situated
across far northern maine will slowly work its way southwest
into northern zones overnight. This boundary will be the focus
for occasional showers (maybe a rumble of thunder far north)
first pushing into northeast zones this evening and then into
central and eastern zones after midnight. Expect QPF to be on
the light side... Generally less than a quarter inch. The
remainder of the area will see increasing clouds overnight. Lows
will range from the mid 50s north to the mid 60s south.

Short term 6 am Saturday morning through Saturday night
Cold front will continue to push south on Saturday gradually
shifting into southern new england by evening. Although clouds
may limit heating ahead of the front in southern new hampshire
and southwest maine... Expect enough instability to develop
during the morning hours to pop off scattered convection in the
afternoon. With freezing levels on the high side and marginal
shear not looking for severe storms but healthy pwat's
approaching 1.5 inches will contribute to heavy downpours. High
temperatures will range through 70s across western maine and
northern new hampshire. Southern new hampshire will range
through the 80s.

Showers and thunderstorms will gradually push south of the
region Saturday evening and high pressure will build in from the
northeast after midnight. Increasing onshore flow will bring
ocean stratus into southern new hampshire and southwest maine
overnight and areas of fog will be likely as well. Low
temperatures will range through the 40s in northeast zones and
lower to mid 50s in the cloudier southwest.

Long term Sunday through Friday
Forecast area will be situated north of a backdoor cold front
Sunday and Monday. While we are not expecting widespread rain to
wash things out, it does look cloud and much cooler than normal
both days. There could also be fog, especially at the coast.

Chances for showers increase across southern zones - they'll be
closer to the frontal forcing. Overall, not the best way to end
the holiday weekend, but it could be worse. The low level
maritime air mass should be displaced by a cold front Monday
night allowing for much better weather for Tuesday - including
highs back into the 70s to 80s again. Fair weather continues
Wednesday and Thursday with high pressure in control. Low
pressure, possibly what's leftover from alberto in the gulf of
mexico could visit our region and bring some rain late in the
week.

Aviation 03z Saturday through Wednesday
Short term...VFR tonight.VFR with areas of MVFR ifr ceilings
and vsby in showers and thunderstorms Saturday. Ifr lifr
ceilings and vsby developing in southern new hampshire and
southwest maine Saturday night.

Long term... MVFR to local ifr CIGS on the coast and perhaps
across southern nh Sunday into Monday (especially at night) with
onshore flow.VFR returns later Monday night through Wednesday.

Marine
Short term... Continuing sca's through 800 pm. Sca's may be
needed again late Saturday night.

Long term... SCA possible Sunday and Sunday night for the ocean
waters and possibly briefly in the bays.

Fire weather
Back door cold front will bring showers into the region
overnight with showers and some thunderstorms continuing on
Saturday. Moist onshore flow will set up behind the front for
Saturday night and Sunday. No fire weather issues are
anticipated through the period.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... 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.
