Re: La Nina
Trade winds are stronger than average across the western half of the tropical Pacific.
Cloudiness near the date-line has been below average during the past few months.
The majority of dynamic computer models predict neutral conditions to continue through the southern summer, however, some models are predicting a return to La Niña conditions.
- So it might not last anyway...
Probably most important thing for us is those trade wind anomalies, which suggest the highs continuing to stay nicely south.
(Could end up giving Northland another cloudy summer though?)

Re: La Nina
Hmmm looking very similar to last year which is not a good sign. Especially with the dry spring many places had.
