More snow around the Southern Lakes in the last 24 hours with another 15cm at Treble Cone and around 5-10cm in nearby resorts. The temperature has warmed up and today looks to be wet for Canterbury with significant precipitation and some may fall as wet snow.

There should be some snow up north around Ruapehu before the wet weather arrives tomorrow. In the Southern Lakes there is the possibility for some good overnight snow starting late and finishing by the morning. Temps are a little warm so keep an eye out for that. The winds are strong everywhere north of the Southern Lakes, so take care.


Low pressure is still moving past the south as the high pressure is causing these north northwesterly winds bringing warmer air down. Source: Metservice (vandalised by the Grasshopper).


Friday July 16

Ruapehu: Another snowy day forecast warming up throughout the day and evening. Provided rain stays away we could see accumulations again around 3-10cm. Strong northerly winds especially overnight.

South Island: Should snow early on but temps rise during the day with the possibility for some showers. Winds west northwesterly and accumulations around 5-20cm again are possible with especially heavy falls possible overnight, but fluctuating freezing levels and rain threaten to dampen the mood. In Canterbury expect a wet day with what could be significant rain.

Extended Forecast

It’s been a wet and wild week around the country and it’s not slowing down yet. We have seen good snowfalls around the south and particularly up high. There is still more to get out of this week before we get a quick reprieve early next week then a return to stormy weather. If you are out there stay up high where the snow quality should be a little better.
