Simple solution, more it north of the wairoa river mouth. We won't get bugger all rain and the water is fine and dandy.
Don't know what forecast you looking at, but from what I could see through the net, the only rain forecast is a shower or two and 2mm at best, hardly going to turn the ocean to custard. The sea is mint at the moment. That off colour water is bringing in plenty of day time snapper.
Rare sight them westers, good to see em in the forecast
