Weather in Napa in November

Prime time. If you get to pick your dates, November is the one. Highs average 19.5 °C, lows 8 °C, and rain falls on 7 days — nothing in the month is working against you.

November ranks 5 of 12 in Napa: past the worst of the year but short of May, which is the month to book if the dates are open.

Rain on 7 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average November reaches 30 °C. Across the twenty years measured, the hottest November day reached 32.3 °C and the coldest night fell to -1.3 °C, and the wettest single day dropped 56 mm — roughly 78% of the month's rain in one day.

November is moderately variable: 18 mm in the driest year against 191 mm in the wettest, around an average of 72 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind is light at 5.2 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. Rain is the thing that moves: December brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in November

November sits at the dark end of Napa's year — 10.1 hours of daylight against 14.8 at midsummer, losing 0.9 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

An inland climate

With no coast nearby, the year swings a fair way — 28.6 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

November in Napa versus nearby

If Napa is one option among several, the nearby comparison is worth making. San Francisco is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Sacramento is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: November works, with May the better month by 11 points if the dates can move. If they cannot, nothing here should stop you booking.
