What you get

More than temperature

Check the air before opening the windows: pollutants, pollen and visibility are updated with every forecast.

Rain in the next hour

See the next sixty minutes of rain or snow as a simple bar, and get a heads-up before the first drops fall.

Ten-day outlook

A clear daily strip with the essentials, and an hourly view when you need to pick the best window for a run.

Alerts that matter

Choose which alerts you want: severe warnings only, or also gentle reminders like a frost overnight or high UV at noon.

About Clearcast

Weather is local, and a national forecast rarely tells you about the shower that will hit your street at 17:40. We use high-resolution radar and short-term models to give a minute-by-minute picture for the next hour, then hand over to longer-range models for the week. Alerts are limited to what matters for your saved places, and you decide how loud they are allowed to be.

How it works

  1. 1Allow location access or search for a city.
  2. 2Choose which warnings should notify you.
  3. 3Check the day ahead in a single sentence.
  4. 4Follow the forecast for family and friends far away.

Frequently asked questions

How often is the forecast updated?

Hourly for the next two days and four times a day for the longer outlook. Severe weather alerts are pushed as soon as they are issued.

Can I follow more than one place?

Yes. Save as many locations as you like and switch between them with a swipe. Each one keeps its own alerts.

Where does the forecast data come from?

We combine several public meteorological models and pick the one that has been most accurate for your area over the last weeks.
