On average, about nine tropical cyclones form in the South Pacific tropics between November and April. Three or four of these leave the tropics and nearly all of them undergo a marked transformation to a mid-latitude depression – a completely different weather system – before they reach New Zealand. For a while after this extra-tropical transition, the system may be referred to as “low formerly cyclone so-and-so”.

We have added a new feature to the "towns & cities" section on metservice.com. "Past Weather" is now located below the ten day forecast for most locations showing wind, air temperatures and rainfall in a graphical format.

- the highest wind gust
- the direction the wind was blowing from
- the highest and lowest air temperatures; and

Summer is the time of year when there's lots of pollen - and hayfever - around. Pollen grains are shed from flowering plants and are typically 15 to 50 millionths of a metre across - about the same width as a human hair.
