Inversion? What inversion...

There is a big inversion in place already.
It'll do 2 things. Stop thermals rising much above 4500ft and make the day go blue from 1-2pm onwards.

West to SW wind is forecast to blow all day, and probably at sufficient strength to keep any sea breeze at bay.

Will we get wave? Probably, but will it be good enough to use to cross the ridge?? Not sure.
It'll be a ridge day for sure, for sure. But how good?

To add to the mix the squiggly lines are suggesting some high cloud late in the day...probably from the front hitting the lower South Island.

Poripori at 1pm. Bases at 4000ft and going blue. Note the increasing wind with height...blue wave?

Te Papa at 4pm. Te Papa...where's that??? It is not the National Museum, it's the intersection of the road between Tirau and Rotorua.
Note the lines coming together near the top of the graph...
