Canterbury Snow Outlook

The 14-day picture — the days worth watching.

Issued Monday 29 June 2026, 07:58 NZST · Outlook period next 14 days

The fortnight is largely settled, but a sustained cold spell from Sunday through next Thursday is worth keeping an eye on.

Tomorrow through Saturday shows nothing — the guidance is flat and there is no signal worth mentioning for that stretch.

From Sunday onward it is a different picture. A multi-day window opens with a real chance of snow on the hills running from Sunday through next Wednesday, peaking around next Monday and next Tuesday where the hills chance sits in the upper twenties to mid-thirties percent range — a meaningful minority outcome, not the expected one, but enough to plan around. The plains carry a lower but still notable chance across the same period, particularly next Monday and next Tuesday at around 24–27%. Next Thursday the signal fades to a low chance on the hills before dropping away to nothing by next Friday.

This is still a week out, so the detail will sharpen considerably before it arrives. The guidance has been stable across recent runs, which gives some confidence that the broad shape is real — but at these lead times and these probability levels, treat it as a heads-up rather than a certainty. The Canterbury Snow Forecast will take over as the window closes.

The next Canterbury Snow Outlook goes out on Monday 6 July, or sooner if the picture changes. If a snow event moves within three days, paid subscribers also receive the detailed Canterbury Snow Forecast — the town-by-town, pass-by-pass picture.
