Questions
How accurate are these forecasts?⌄
It depends on the model and how far out you're looking. GraphCast beats the old-school forecasts on 90%+ of metrics out to 10 days (published in Science, 2023). FourCastNet is strong on extreme weather within a 6-day window. Prithvi WxC takes an existing forecast and zooms it in — so its accuracy depends on the input. Every forecast shows you exactly what the model said, hour by hour, so you can see for yourself.
Is my data private?⌄
Yes. Your searches and saved forecasts are yours. We keep logs for 30 days for debugging and then throw them away. We never sell your data.
What happens if a model is wrong?⌄
Models get it wrong sometimes — physics is hard and the atmosphere is chaotic. We don't hide that. Every forecast shows you what the model said and how confident it is (when the model tells us). If GraphCast predicts rain and it's sunny, you can see exactly where the model drifted.
Can I use this for my business?⌄
Yes. Every model we serve is open-source and commercial-friendly (Apache 2.0, BSD-3, or US Public Domain). We deliberately don't serve Aurora or Pangu-Weather — their licenses are research-only. You don't need to worry about attribution; we handle it.
Do I need to code?⌄
No. Pick a spot, pick a model, click run. That's it. If you do want to automate (ping your Slack when frost is coming, pull forecasts into a spreadsheet), there's a developer path too — but it's optional.
What's the free plan?⌄
500 checks a month. That's enough for about 100 GraphCast runs, 50 hyperlocal zoom-ins, or unlimited baseline Open-Meteo forecasts — no card required. Academic emails (.edu, .ac.uk) get 750. If you hit the limit and want more, plans start at $29/month.
Forecast your spot in 30 seconds.
No card. No install. Free for your first 500 checks every month.
