Weather in Irvine in November

Prime time. If you get to pick your dates, November is the one. Highs average 20.2 °C, lows 15.6 °C, and rain falls on 3 days — nothing in the month is working against you.

November ranks 7 of 12 in Irvine: past the worst of the year but short of June, which is the month to book if the dates are open.

Rain falls on only 3 days, so an itinerary with no wet-weather fallback is a reasonable risk. 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; the day barely swings — 4.6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest November day reached 29.7 °C and the coldest night fell to 8.7 °C, and the wettest single day dropped 48 mm — roughly 192% of the month's rain in one day.

This is the volatile part. November rainfall has ranged from 2 mm to 83 mm across the twenty years measured — a 81 mm spread around an average of 25 mm. The average is real but almost no individual November looks like it, so treat the figure as the middle of a wide range rather than a forecast.

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 67%.

How November sits in the year

The month is on the way down: 2 °C cooler than October, with December dropping another 2.7 °C. The first week and the last are not the same trip.

Daylight in November

November sits at the dark end of Irvine's year — 10.4 hours of daylight against 14.4 at midsummer, losing 0.8 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

An inland climate

Despite being inland, the year stays fairly even: 10.7 °C between the year's warmest afternoons and coldest nights.

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 Irvine versus nearby

If Irvine is one option among several, the nearby comparison is worth making. Riverside is close enough to be a coin toss — 4.6 °C warmer, 1 day more rain. Los Angeles is close enough to be a coin toss — 3.9 °C warmer, the same number of rain days.

So: November is effectively as good as it gets here — 6 points behind June, which is inside the margin where the weather stops being the deciding factor and price starts being it.
