Weather in Greymouth in November

Shoulder season. November is shoulder season in Greymouth — cheaper, quieter, and a genuine gamble. You should expect rain on 16 days of the month, which is more days wet than dry.

November ranks 6 of 12 in Greymouth: past the worst of the year but short of February, which is the month to book if the dates are open.

This is wet-season rain: 16 wet days and 6 genuinely heavy ones, which in this climate means concentrated downpours rather than all-day grey. The pattern is usually a clear morning and a loud afternoon, so front-load the day and stop fighting the 3pm hour. Pack for 16 °C days and 10.5 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 5.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest November day reached 22.4 °C and the coldest night fell to 4.8 °C, and the wettest single day dropped 55 mm — roughly 35% of the month's rain in one day.

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 255 mm against 49 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 158 mm average is a reasonable planning figure, not a promise.

Wind is light at 4.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.

How November sits in the year

The month is on the way up: 1.6 °C warmer than October, and December adds another 2 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in November

14.5 hours of daylight, gaining 1.1 hours across the month. That is between Greymouth's extremes of 15.3 and 9.1 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 14.7 °C in November — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 18.5 °C in February and bottoms out at 13.3 °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

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 Greymouth versus nearby

If Greymouth is one option among several, the nearby comparison is worth making. Waikowhai is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Christchurch is a better bet in November — 3.4 °C warmer, 4 days less rain.

So: November is a compromise. February is 19 points better and is what Greymouth is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
