Best time to visit Greymouth

New Zealand · 20-year averages

February is the best month in Greymouth, scoring 72 out of 100, with August the weakest at 39. The 33-point spread means timing is worth planning around without being decisive. The good window runs January to March — 3 months within ten points of the best.

February is the warmest month at 19.6 °C and July the coolest at 11.2 °C — a 8.4 °C spread across the year. It never reaches 30 °C in an average year, which takes heat off the list of reasons to avoid any particular month.

There is a real wet season here. June, August, September, October and December carry the rain — up to 19 wet days in a month — while February to March drop as low as 13. That 6-day gap is the biggest single difference between a good month and a bad one in Greymouth, and it moves further than the temperature does.

The sea peaks at just 18.5 °C, which is wetsuit territory even at its warmest — a coast to look at rather than swim in. Daylight runs from 9.1 hours in winter to 15.3 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are February, January, March. The one to think twice about is August. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
