Trend Summary
After a stretch of dry, mostly clear weather through the end of December, conditions turn cooler and wetter around 2 January. Temperatures drop below freezing on the morning of the 26th and again on the 4th, with frost and a hard freeze possible on the latter—this is the coldest night of the period.
From 2 January onward, light rain becomes more frequent, especially on the 5th and 6th, with the heaviest and windiest conditions expected on 6 January (gusts near 73 km/h). Rainfall totals are not extreme but could lead to damp, slippery conditions. The wet period ends by the 8th, with drier air returning.
No snow is indicated at sea level. However, brief freezing drizzle cannot be ruled out on the morning of the 26th and especially the 4th, given wet-bulb temperatures near or below 0°C and surface temperatures at or just below freezing. Any such occurrence would be brief and localized, with no significant accumulation expected—even on grass or untreated surfaces.
Model trends have been stable in recent runs, with little shift in temperature or precipitation timing. Confidence is high through 3 January; beyond that, exact timing of rain and wind on the 6th and 7th remains somewhat dependent on low-level flow details, though the overall pattern is consistent.
Practical advice:
- 25–30 Dec: Excellent window for outdoor plans.
- 31 Dec–2 Jan: Cool and cloudy; prepare for damp conditions.
- 4 Jan: Coldest night—protect pipes, cover sensitive plants.
- 6 Jan: Windy and wet—avoid exposed areas, allow extra travel time.
