Detailed Forecast

Thursday 23 August – Ruapehu’s pummelling continues, a little bit of everything down south


Synoptic Outlook

The pummelling continues on Ruapehu, complete with heavy snowfalls, some rain, gale NW winds and blizzard conditions. The first half of Friday will be much the same as a low-pressure system passes over the North Island.


This low will suck in a cold breeze over the South Island during the latter half of Friday, giving southern ski fields just a light dusting. This is a far cry from the sizeable powder dump that earlier forecasts were indicating for Canterbury.


After a brief weak ridge on Saturday, a front and low combo get snowfalls going over the South Island during the second half of Sunday.

The pummelling continues on Ruapehu as a complex low-pressure system works its way over the Country. Southern ski fields will get off lightly while sitting in the shelter of the Main Divide, and will just see a little bit of everything. Source: NZ Metservice (vandalised by the Grasshopper)


Thursday 22 August

Plenty of sunshine amidst a partly cloudy day for the South Island. NW winds, fairly strong in Canterbury.


Snow on Ruapehu with heavy falls, especially first thing this morning when it’ll be falling as rain below 1700m before colder temps lower snow levels to about 1400m. Gale NW winds with blizzard conditions.


Friday 23 August

Cloud clears the South Island during the morning for a dose of sunshine, but returns again in the afternoon as a chilly southerly breeze develops, pushing in some light snowfalls.


Heavy snow on Ruapehu during the morning, but rain will fall below 1700m again as mild NW winds blow a gale with blizzard conditions. Snow will gradually lower to base elevations during the afternoon, as winds turn to a lighter and chillier W-SW breeze, while also petering out.


Saturday 24 August

Any morning cloud over the South Island clears to a mainly fine day, although there’ll be some mid-high cloud over the Southern Lakes. W-NW winds rise to gale.


Cloud and the odd snow shower or flurry on Ruapehu as strong southerlies turn to the SW.


Sunday 25 August

Variable high cloud and gale NW winds over the South Island to start with. Snowfalls then get going sometime during the second half of the day.


Snow flurries and showers on Ruapehu with gale W-SW winds.


Extended Outlook

Snowfalls continue across the country during Monday and into early Tuesday as the front and low combo leave a chilly SW flow behind.


Another handy top-up is lined up for next Thursday-Friday as this procession of frontal systems continue, although some rain is likely to fall on lower slopes of Canterbury and Ruapehu.
