We’re now on the cusp of a dynamic, tropical induced blocking pattern with low pressure hiving off an active monsoon trough in the Coral Sea and meandering in Coral Sea before drifting down into the Northern Tasman. The high pressure belt holds good support for this low pressure area with reinforcing cells stacking onto a slow moving system located at South Island latitudes. This will see an extended E’ly swell event, with days of pumping E swell ahead.

We’re now on the cusp of a dynamic, tropical induced blocking pattern with low pressure hiving off an active monsoon trough in the Coral Sea and meandering in Coral Sea before drifting down into the Northern Tasman. The high pressure belt holds good support for this low pressure area with reinforcing cells stacking onto a slow moving system located at South Island latitudes. This will see an extended E’ly swell event, initially favouring sub-tropical areas and then spreading south to temperate NSW later this week. 

The new, long-period W/SW groundswell has hit Cape Sorell and we should see step-ladder sets developing from late morning.

The high in the Tasman does set up a more local NE fetch though, with some chunky NE swell expected to develop Mid week.
