Hi WW, I am a bit confused with today’s forecast so am hoping you can put me right.

In your heading you say a SouthWesterly air flow lies over the country which I assume is all of NZ but in the Northland Auckland forecast you say we will have Northwesterly winds. 

Can you please tell me why this is and what the difference is here?

Thank you for any response.

Hi there

The overall general flow is yes a southwesterly. But sitting off the west coast of the North Island is a low pressure system directing a more west to northwest airflow over the upper North Island, it would have been more prudent for me to mention this in the outline above so thankyou for mentioning this. Often it becomes complex to mention every detail in that outline, mostly we are just looking at the overall picture in that part of the forecast.

But yes, geneally the weather over the country is coming from the southwest. There will often be different winds for various regions in different overall flows.

In Canterbury in a northwest airflow we often get a northeasterly in Christchurch for example.

Thanks for writing in.

Thank you for your response, I did think that something like that was the reason and can understand why you did not mention it. Thank you.
