Daytime highs in the upper teens at first, above average for October, look set to ease back into the low teens later on, below average. Temperatures peak on Tuesday 6 October at 19°C, before a sharp drop in daytime temperatures around Wednesday 7 October brings fresher conditions. Later in the period there are signs of lows near -2°C, though that far ahead the timing is uncertain. With temperatures predicted to fall to or below freezing, overnight frosts are likely, particularly during any clear spells.

There will be some wet spells, with rainfall totals near 21mm over the period. Colder interludes may bring a risk of sleet or snow.

These forecasts use interpolation to improve accuracy for your specific location, and are powered by either ECMWF or GFS model data depending on your selection. As with all weather forecasts, confidence decreases rapidly beyond 5 days ahead — treat the later dates as a heads-up about possible conditions rather than a firm prediction.
