Hilarious that In,gill gets a wind icon for today and tomorrow yet Wellington doesn’t. We are not currently under a watch or warning!

Wind icon in our forecast don’t indicate warnings – it just means it may be a bit windy.

I was wondering what makes WeatherWatch more accurate than the Android weather app?
Couple days ago, the weather app showed a forecast for thunder and rain, whereas WW showed less than 50% chance of rain, which ended up being a lot more accurate.
Cheers,
Cameron.

Hi Cameron, We use The Weather Company – as they are the world’s most accurate weather forecaster, whereas Android phones get their data from a variety of sources. We also add our own formula to some of the data, to improve it in New Zealand due to: 1) NZ’s rugged topography, and 2) The lack of open data from the two commercial Government Agencies (Niwa and MetService).
This forces us to do better – but if we had Government/public weather data (like all other modern nations) we’d be able to nail all isolated downpours/showers too. That is a blindspot the Government has purposely created to keep their two Weather Agencies more commercially viable/relevant.
Also, in Auckland, we manually adjust some forecasts. Wish we had the resources to do that for everyone. 🙂
Thanks for the message
Cheers
Phil D
