Weather Metric is a free UK weather tool for people running building sites, on the web and on iPhone. This page is how to get help with it, and what it does and does not do.
It goes straight to Chris, who built it and reads them himself. Usually answered within a working day or two. It helps to say which site or postcode you were looking at, whether you were on the app or the website, and what you expected to see.
There is also a feedback box on the tool itself, under Ask for something at the foot of any tab. It reaches the same place and needs no sign-in.
Yes, and it stays free. There is no account, no subscription, no in-app purchase and no advertising. It is a free side product of Construction Metric, and it earns its keep by showing what that record keeping is like.
No. Type a postcode and it works. Nothing is held about you unless you choose to register for the emails or send feedback.
Measured rainfall comes from the nearest Environment Agency rain gauge, and the record names the station and states its distance from your site. Forecast and modelled conditions come from Open-Meteo, which blends the Met Office, ECMWF, GFS and ICON models. Daylight is computed from your coordinates. Warnings come from the Met Office. Radar and the live map are Windy.com in their own frame. The record always says which kind of figure it is showing, because measured, modelled and computed are different kinds of claim.
Forecast, radar, daylight and air quality cover the whole United Kingdom. Measured rainfall depends on Environment Agency gauge coverage, which is England, and the record always states the distance to the nearest gauge so you can judge whether it speaks for your site. Live traffic cameras are London only, through Transport for London open data.
Only to centre the forecast on where you are standing. You can type a postcode instead and never grant it. The coordinates are sent to the server to fetch the forecast for that point and are not stored against you.
No, and they are not meant for that. They are a planning aid set to figures you choose yourself, and the wind figure is a forecast at 10 metres, not a reading at the hook. The lift plan, the crane manufacturer’s own limits, the crane’s anemometer and the appointed person decide whether a lift happens. Nothing on the page authorises work or clears a site after lightning.
One click on the link at the foot of any Weather Metric email. There is no sign-in, and it stops both the Monday forecast and the daily limit warning at once.
Only what you type. If you register for the emails: your address, company, occupation, the site you named and the working limits you set, so the emails can be about your site rather than a generic one. If you send feedback: the message, and an email address only if you give one for a reply. There are no accounts, no advertising and no tracking across other sites.
Unsubscribing removes you from the list. If you want everything erased instead, email and say so, and it will be done and confirmed.
Please report it. Say which site or postcode, what the page showed and what you expected. An error in a weather record matters more than most bugs, because people keep these figures.
Free, with no purchases of any kind, and it needs iOS 16 or later. It shows the same tool as the website and fetches live data, so it needs a connection to show anything new. If a screen stays empty, check the signal first, then email and say which screen it was.
Location is optional. The app asks only when you press My location, and you can use a postcode instead and never grant it.
Weather Metric is made by AI Metric Ltd, a company registered in England and Wales, number 16448110, in Liverpool. It is a free side product of Construction Metric, which keeps the whole site record: the WhatsApp photographs, the diaries, the documents and the programme.
