A cool southerly is advancing up the eastern part of the South Island today/tonight and is expected to move over the North Island tomorrow and affect eastern and northern areas. Not too much rain is expected overall but it will feel quite chilly at times in the wind in exposed areas.

Apart from that dampness and nippy air by the fleeting southern ocean visitor, the rest of the week looks generally fine and settled.

Western regions should see most of the sunshine with pleasant daytime highs but cool nights are expected under clear skies. There could be light frosts in inland areas of the mainland midweek.

By the end of the week, the country should still be bathed in sunshine but the southwest corner of the country might see some cloud move in, with a nor’ wester picking up.

Nationally and how it’s shaping up…

Coolest day: Tuesday 

Warmest day: Friday 

Sunniest days: Thursday and Friday 

Frostiest nights: Mon, Tues and Wed. in inland South Island regions

Wettest: Some eastern/northern areas late today/tomorrow/clearing early Wed ( but nothing too major at this point)

Windiest: Late today/tomorrow as the southerly advances north and the cold is felt mainly in eastern and southern districts.
