Weather in Tri-Cities in November

Shoulder season. November is shoulder season in Tri-Cities — cheaper, quieter, and a genuine gamble. Highs sit at 11.8 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

November ranks 8 of 12 in Tri-Cities: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain on 8 days, 0 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 11.8 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 7 nights fall below freezing. Across the twenty years measured, the hottest November day reached 23.3 °C and the coldest night fell to -7 °C.

November is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest November on record still delivered 54 mm against 8 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 29 mm average is a reasonable planning figure, not a promise.

Wind is light at 9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How November sits in the year

The month is on the way down: 7.5 °C cooler than October, with December dropping another 5.1 °C. The first week and the last are not the same trip.

Daylight in November

9.5 hours of daylight, losing 1.2 hours across the month. That is between Tri-Cities's extremes of 15.8 and 8.6 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 34.6 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

November in Tri-Cities versus nearby

If Tri-Cities is one option among several, the nearby comparison is worth making. Spokane is the weaker option in November — 4.7 °C cooler, 6 days more rain. Portland is the weaker option in November — within a degree on temperature, 11 days more rain.

So: November is a compromise. September is 32 points better and is what Tri-Cities is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
