Your thermometer says 18°, the Project Planner says 16°. Neither is wrong: they're measuring different things. Here's why, and how to use the numbers you trust.
Why It's Different
- It's for an area, not your garden. Weather services work out the weather over an area of several kilometers, or use the stations nearest to it. Hills, water, towns and a sunny wall all change what your own thermometer reads.
- The newest days aren't settled. Services can take up to a week to finish the latest days, so they can change after you first look.
- Past days get corrected. Now and then a service improves its data, and older days change a little.
Try Another Weather Source
- Press Weather Source above the weather.
- Choose Meteostat for measurements from real weather stations near your place, or another Open-Meteo model.
- Press Save and Search, and compare.
See what each source and model is in Weather Sources.
Fix a Few Days
- In the table under the chart, press the number you want to change. Edit Weather Data opens on it, with every day's weather in a grid.
- Type your reading and press Enter. Change as many days as you like; to paste readings from a spreadsheet, copy them there and paste them on the first day.
- Press Apply.
Use Your Own Readings for Every Day
If you've kept a log, from your own thermometer or a weather station nearby, bring it all in at once:
- Press Download at the top of the Weather step, then Download CSV.
- Open the file in Excel, Numbers or Google Sheets. Put your readings in place of the ones there, keeping the dates and the column headings, and save it as CSV.
- Press Edit, then Import File, and choose your file. The values it changes are marked; check them, then press Apply.
What the file needs is in CSV File Requirements.
Keep the Weather From Changing
A saved project keeps its weather. Opening it never looks the weather up again, and its saved days only change if you use Check for Updates and choose the new values. A gallery page keeps the weather it was published with, too.
A link doesn't carry the weather, though: whoever opens it gets the weather fresh.
The easiest way to share your weather is your project's gallery page: Open a Copy there opens it with the weather it was published with.
To send someone your weather exactly as it is, without a gallery page:
- Wait until your last day is about 6 days ago with Open-Meteo, or 8 with Meteostat, so it's settled.
- Press Download at the top of the Weather step, then Download CSV, and send them the file with the link.
- They press Edit, then Import File, choose that file (without changing it), and press Apply.
Their weather source then shows Custom.
If Something Goes Wrong
Pressing a value does nothing
With Grouping set to Weekly, the table shows weeks, which can't be changed. Press Edit › Edit Weather Data instead: it always shows days.
Apply is greyed out
Nothing has changed yet. A value typed the same as it was isn't a change.
Some rows were skipped
The import lists the rows it couldn't read. Usually it's a date in another format or a heading that was changed. Check them against CSV File Requirements, and import again.
I can't change the place or dates any more
They're locked so your weather isn't replaced by accident. Press Reload Weather Data to go back to the weather source (your changes are lost), or start a new project.
Someone opened my link and saw other weather
A link doesn't carry edited weather: it's looked up again. Send them your CSV file to import.
It still looks wrong
Press Weather Data Feedback under the table to tell me about it.
