A topsy-turvy month in terms of temps, but generally a little warmer than normal for most places. October also saw frequent strong wind events and a few mid-spring snow events. During the last few days Ex-TC Lola delivered an extra 1-2 months of rainfall to parts of Northland and the Coromandel Peninsula, accompanied by severe easterly gales for the upper north.
