Hi weather watch How much rain would nelson need to make the grass on the moutains around the city to go green?

PAUL Cornille on 12/03/2026 6:05pm

Hi Can you please advise where i can find daily soil temps ?

WW Forecast Team on 12/03/2026 7:17pm

Hi Paul, sadly in NZ the Government has commercialised this historical information via MetService and Niwa. (In all other modern countries it is easily freely available from sites like ours). We suggest your local council, as they often have some good public data (although not all do). Failing that, email Niwa and simply ask them to find out for you.
Kind regards,
Phil D

Hi Team, where do I go on your website to find how the highs and lows are predicted to be in 2 weeks time, as shown in your monthly climate watch. Maybe you could look at do a mid month climate watch. In this instance I am looking at planning something for the weekend 7th/8th March. I am sure there are interested people out there.

WW Forecast Team on 22/02/2026 10:27pm

Hi Bruce, forecasts don’t generally go out more than 10 to 15 days in our part of the world, as they aren’t reliable beyond that point. We are thinking about doing mid-month climate updates though, just not quite there yet.

Kind regards
– WW

Hello, we are hosting the RC Aerobatic NZ Masters & F3A World Cup event in Hamilton (https://maps.app.goo.gl/R17Q8bdwDwNbJqaq6) from 27 Feb to 1 Mar and will be welcoming a number of international competitors.
We are closely monitoring the expected wind conditions and rainfall over those dates. Would it be possible to provide detailed wind forecasts and probability of rain information for the Hamilton Model Aero Club during that period please.
We really appreciate the work you do — thank you in advance for your help.

For (yacht) offshore sailings our best planner is Maritime wind forecasts. NZ being an island I think the same reports would provide the critical info you require for flying events

Alison on 13/02/2026 11:16am

Hi team, just a heads up, the IAUCKL797 isn’t showing any rain readings, and it would have got a good bit of rain fall recorded today. Does it need a reboot to start getting data back? Thanks team, love your work you do for us, and LOVE the app ❤️
