Canterbury Snow Outlook

The 14-day picture — the days worth watching.

Issued Monday 17 August 2026, 07:58 NZST · Outlook period next 14 days

Two days carry a watch flag this fortnight — tomorrow and Monday (31st) — but both are low-chance signals, not looming events.

Tomorrow is the stronger of the two. Forecast guidance has held this signal steadily across the last several runs, which is reassuring, but the chance remains low — around 11% on the hills, rising to perhaps 18% at the upper end. That puts it firmly in keep-an-eye-on territory rather than act-now territory. The detail for tomorrow is covered by the Canterbury Snow Forecast. The rest of the near-term window — Wednesday through Sunday — is flat and unremarkable.

The second flag sits at the very edge of the outlook on Monday (31st). At 14 days out the numbers are tentative by nature, and here they are genuinely modest: a low chance on the hills, with the upper end of guidance nudging just into double figures. It earns a mention because the guidance flagged it worth watching, not because it looks like a significant event at this range.

Beyond those two days, the fortnight is quiet. Nothing else in the window is showing a meaningful signal.

The next Canterbury Snow Outlook goes out on Monday 24 August, 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.
