Wellington's Weather Tendencies

So we have quite a temperamental climate in Wellington which likes to change it's mind almost everyday. I have looked into the climate profile for Wellington to get a bit of a better understanding of how to design my space. I will need to keep in mind providing shelter from both the sun and wind/rain. I have found the website myweather2.com which provides insight into weather tendencies month to month for cities around the world.. 

All of the below statistics can be found at:

I am not going into detail on this blog for the average sunshine hours, precipitation, temperature etc. for each month of the year for Wellington however I will have an overview look at the year:

Due to the fact that students and most staff are not at Massey over January/early February, I feel that for my public space shelter from the rain and wind is going to be more of a focus rather than the sun. We get sunny days all year round don't get me wrong, however looking at the graphs, the probability of rain and wind is much higher than having hot sunny days. Obviously when it is raining and windy, people would rather be inside anyway, however I want there to at least be one area of my public space that people can enjoy no matter the weather.
