Weather in Napa in February

A good month. February works. It is not the peak, but nothing about it fights you. Highs average 15.8 °C, lows 5.9 °C, and rain falls on 9 days — nothing in the month is working against you.

February ranks 10 of 12 — near the bottom of Napa's year. May is the month that works, and the swing between the two is 40 points, which is a different holiday rather than a slightly better one. Worth keeping in perspective: February is the weakest month of Napa's year and it is still a perfectly good one. The downside here is small.

Rain on 9 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 15.8 °C days and 5.9 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest February day reached 25.7 °C and the coldest night fell to -1.3 °C, and the wettest single day dropped 68 mm — roughly 56% of the month's rain in one day.

February is moderately variable: 0 mm in the driest year against 331 mm in the wettest, around an average of 122 mm. Roughly two Februarys in three land near that average, and the third does something else entirely.

Wind is light at 5.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, high enough to notice on the warm days without dominating them.

How February sits in the year

Temperatures hold steady either side: 14.6 °C in January, 15.8 here, 17.8 in March. Nothing about the timing within the month matters much.

Daylight in February

10.8 hours of daylight, gaining 1.1 hours across the month. That is between Napa's extremes of 14.8 and 9.5 hours, so days are long enough not to constrain the plan.

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

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.

February 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: February is a compromise. May is 27 points better and is what Napa is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
