Weather in Trondheim in November

The month to avoid. November is the month most people should skip in Trondheim. Highs sit at 3.1 °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 Trondheim: past the worst of the year but short of July, which is the month to book if the dates are open.

Rain on 18 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 3.1 °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: 14 nights fall below freezing; the day barely swings — 3.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest November day reached 11.9 °C and the coldest night fell to -18.5 °C, and the wettest single day dropped 41 mm — roughly 34% of the month's rain in one day.

November is moderately variable: 21 mm in the driest year against 276 mm in the wettest, around an average of 122 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind is light at 3.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 95%, which at 3.1 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How November sits in the year

The month is on the way down: 5.3 °C cooler than October, with December dropping another 2.1 °C. The first week and the last are not the same trip.

Daylight in November

6.8 hours of daylight, losing 2.9 hours across the month. That is between Trondheim's extremes of 20.5 and 4.6 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 8.9 °C in November — too cold to swim without a wetsuit. The sea peaks at 14.2 °C in August and bottoms out at 6.1 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

November in Trondheim versus nearby

If Trondheim is one option among several, the nearby comparison is worth making. Oslo is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Bergen is close enough to be a coin toss — 2.4 °C warmer, 3 days more rain.

So: November is a compromise. July is 48 points better and is what Trondheim is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
