Seacoast NH Weather

10/14/2026

Major arctic cold outbreak for mid October is coming on Saturday

A gusty windy day with gust to 40 mph on Saturday with North northwest winds.

Don’t climb the presidentials or the Franconia ridge trail on Saturday.

Temps will stay in the 30s north and 40s south during the day and we will likely see a freeze across a large portion of the state ending the growing season.

The Seacoast may avoid a freeze because of the wind - but it will be spotty where folks don’t get a freeze.

It will warm after the cold so covering up sensitive vegetation will allow it to continue to bring joy.

Monday night NOAA rainfall prediction

Hope to see lots of this action this winter versus the lack of action (frequency I am referring to) the past few seasons.

Of course in winter this would be rain south of the mountains given the expected low track. Much cooler tomorrow than today.

Sunday night 10.11.2026

Our rain has arrived and we should get 1/2 an inch of rain, except more as you get toward the southern NH Merrimack valley where an inch is possible .

More rain is expected south of NH - MA border.

Less north of Dover - Exit 9 at 1/4 to a 1/3 of an inch , Rochester to Conway a 1/10 to a 1/4 inch is possible.

Active pattern this week

Mild Monday and clearing -

Tuesday - a northern stream low will rapidly deepen to our east, bringing rain and colder temps, more rain north Strafford, Carroll, than Rockingham, most of the rain is overnight.

Weekend had looked nice -

Funny how a rapidly developing tropical depressions can alter a weekend forecast.

Saturday - Breezy but mostly sunny 60s

Sunday - sunny morning clouding up in the pm from SW to NE with Rain possible by mid to late evening Sunday here at the coast later as you go northeast.

Monday - showers

Tuesday - rain possible

This does not appear to be a heavy rainfall for us but as a remnant tropical cyclone it has to be watched to see if it’s heavy rainfall bands come further north.

Most coastal towns should avoid a freeze but if you’re concerned cover up.

Frost Advisories and Freeze Warnings have been issued for locations where the growing season is still active. Widespread frost/freeze conditions are expected tonight. If you still have sensitive plants outside you may want to cover them or bring them inside.

Sunday late fall early winter thoughts

The Euro weeklies continue to model classic El Niño set up.

This is out to mid November 7 day chunk ending Nov 18 2026

It shows the classic above average temps across Canada and the arctic.

This happens due to responses in the pacific that at times flood North America with pacific source region air.

That does not mean temps can’t and won’t be below average in the lower 48 but you can also count on a lack of extreme cold outbreaks for this winter.

Early winter thoughts

Dec +2.0 above average most of New England - precipitation 25 % above average

Jan +1.0 above average, Precipitation 50 % above average.

February +0.0 above average, Precipitation near average

Winter is +1.0 with 25 % above average precipitation

I believe snowfall will be 120 % of average but we will be open to a few warm ups especially in early winter. Christmas week is a good bet for when that warmth arrives or before.

Slow start to winter, strong back half of winter.

Fall colors on the Seacoast seem quite muted this year and from what I have seen from Pinkham notch to Portsmouth is the same.

It remains nice to look at but my two sugar maples typically have a brilliant red but the color is a brown / rust kind of red.

The yellows are yellow but not a bright yellow.

I also think the leaves will fall quickly due to the drought.

10/04/2026

45 day Euro extended adds to deficits as we look for more rainfall prior to ground freeze.

These stats as presented can be both misleading; and misinterpreted.

Over this 45 day period the forecast on this run equals 5.50 inches of rainfall.

All indicators continue to suggest strong El Niño which equals wetter than average.

Broader view of a longer term drought than just this year

Did the recent nor’easter fix the drought? Not quite. While the soaking rain provided a welcome boost to topsoil moisture and brought short-term streamflow improvements, it wasn’t quite enough to to change the US Drought Monitor (USDM) classifications. Because aquifers never fully recharged following the 2025 drought, baseflows plummeted when dry weather returned late this summer. As a result, many lakes and rivers are seeing lower water levels now than at this time last year, even if short-term surface conditions look better. Continuous dryness since June 2025 has created cumulative deficits of 12”+ for most of the region, worst along the Midcoast. With the end of the growing season and reduced evaporation, the trend favors gradual recovery through fall if rain events resume. After today's scattered showers, there is little to no appreciable rainfall expected over the next 7 days, so long-term recharge remains a waiting game.
