Weather in Wellington in June

Shoulder season. June sits in between. You will get good days and you will lose some. Highs sit at 12.4 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

June ranks 10 of 12 — near the bottom of Wellington's year. February is the month that works, and the swing between the two is 36 points, which is a different holiday rather than a slightly better one.

Rain on 13 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 12.4 °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: the day barely swings — 2.8 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 16.3 °C and the coldest night fell to 5.5 °C, and the wettest single day dropped 42 mm — roughly 46% of the month's rain in one day.

June is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest June on record still delivered 158 mm against 43 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 92 mm average is a reasonable planning figure, not a promise.

Wind sits around 19.8 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 84%, which at 12.4 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How June sits in the year

Temperatures hold steady either side: 14.4 °C in May, 12.4 here, 11.5 in July. Nothing about the timing within the month matters much.

Daylight in June

June sits at the dark end of Wellington's year — 9.2 hours of daylight against 15.1 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 12.7 °C in June — too cold to swim without a wetsuit. The sea peaks at 16.8 °C in February and bottoms out at 11.6 °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.

June in Wellington versus nearby

If Wellington is one option among several, the nearby comparison is worth making. Nelson is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Palmerston North is close enough to be a coin toss — within a degree on temperature, 2 days more rain.

So: June is a compromise. February is 33 points better and is what Wellington is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
