    Recreational Marine: Mana
    Marine Weather Situation and Forecast issued at 2252hrs Thursday 18-Sep-2025 by MetService

    Situation:
    A southwest flow over Aotearoa weakens today as a ridge builds over the country. Northwesterlies strengthen over the far south tonight, and the rest of the South Island tomorrow, ahead of a front approaching from the Tasman Sea. The ridge over the North Island moves slowly eastwards as the front makes its way northwards over the South Island during Sunday, stalling in central New Zealand by the end of the day. On Monday, the front lies slow moving over central parts of the country while a northwest flow develops over the South Island. The front crosses the North Island on Tuesday as a second front moves onto the lower South Island.
