Cool change for South Islanders on Wednesday

Wednesday will be colder than average in a number of southern places as a Southern Ocean southerly wipes away the warmer sub-tropical northerly.

Daytime highs on Wednesday will be down with coastal Otago and Southland having highs between 12 and 15 degrees. Inland won’t be so bad, in fact Alexandra has a high of 21 today but is warmer tomorrow with 24 and sunnier skies. So it’s very much a coastal cool down around Southland and Otago.

But further north the cold will slide across the flat Canterbury plains on Wednesday, dropping daytime highs by nearly 10 degrees compared to today. Many places have a high in the low to mid teens (14 or 15).

The cooler change also moves into the Lower North Island but highs will still make the late teens.

Overnight lows are also taking a bit of a drop with some places down to just 3 to 7 degrees inland, with Northern Southland potentially the coolest place overnight tonight/Wednesday AM.

Warmer weather returns by Thursday with Wednesday the main cool day.
