A low will cross the North Island on Thursday while heavy frosts (-5C and below!) will affect inland parts of the South Island as weak high pressure crosses there.

As we head into the weekend colder air moves further up NZ – but high pressure remains just offshore to our west, meaning some areas will have a colder southerly blowing – and maybe a few showers.

There are lows forming all around us – one in the Tasman Sea crosses northern NZ overnight tonight and hangs around on Thursday before clearing east. Other lows surround NZ this weekend.

To our Pacific Island viewers, we also have a tropical low forming near Fiji next week with heavy rain and some wind potential – we comment on this out of season tropical low.

We also have a new website for those of you into boating, surfing – or anything to do with the beach with a new data site giving free access to more useful tools.
