Persistent wet weather is going to affect the West Coast with big fluctuations in daytime temperatures for some in the south too.

The second week of 2018 is dominated by a developing area of low pressure over the South Island pushing patchy areas of rain and showers around the island and even into parts of the North Island by the end of the week.

Temperatures will be a bit flat for some due to this localised low, cloud and cooler winds at times. Some places will only have daytime highs in the late teens, but by this weekend inland parts of Southland and Otago will be closer to 30 degrees.

More rain is also coming to the dry West Coast – this will be welcome news to many.

Elsewhere expect more consistent temperatures and mainly dry weather, especially the upper North Island, however it may be a bit cloudy at times this week.
