The main humid months (70%+) are in late Jan thru to end March, however we
can get very long dry periods in the Far North from Dec thru to end March -
typical sub tropical? Max rain in June thru to August.

From your mail it would seem that the traditional Tuscan varieties would be
ok. The problem we have up here is that these varieties are only just
starting to come to fruit now and therefor we have no real idea of how they
will work.. Koronekei is producing very good crops and excellent oils
however I want to plant 250 new trees (other CV's than what I have) and
start to graft the other 300 to replace the Barnea that appear to be a
dismal failure up here.
kind regards
