Hyperlocal Weather
An air quality forecast — not just today's reading
Most apps show one AQI number for right now. Hyperlocal Weather gives you a true air quality forecast: live AQI with its category and main pollutant, health advice for you and for sensitive groups, an hour-by-hour chart covering the next 84 hours and a 3-day outlook. Free on iPhone & Android, worldwide.
Everything an AQI app should tell you
Advice for you — and for sensitive groups
An AQI number alone doesn't tell your family what to do. Hyperlocal Weather translates the index into plain-language health recommendations: one set for the general population and a separate set for people with asthma or heart conditions, the elderly and children.
- Category, not just a number — e.g. 32 Good, so the index is instantly readable.
- Main pollutant identified — know if PM2.5, ozone or another pollutant is driving the AQI.
- Two-tier recommendations — general population and sensitive groups, side by side.
Pick the cleanest hours before you head out
Because it's a forecast rather than a snapshot, you can schedule a run, a bike commute or the kids' park trip for the hours when the air will be at its best — and see how air quality fits into the wider weather picture for the days ahead.
- 84-hour bar chart — hourly AQI for the next three and a half days.
- 3-day outlook — a quick day-by-day read on where the air is heading.
- Weather in context — pair the AQI forecast with the full daily forecast in one app.
Why an air quality forecast beats a current AQI reading
The AQI (Air Quality Index) condenses pollutant concentrations — fine particles like PM2.5, ozone, nitrogen dioxide and more — into a single number with a category such as Good, Moderate or Unhealthy. A current reading tells you what you're breathing right now. But air quality swings through the day: traffic peaks, wind shifts, smoke drifts in and out. An air pollution forecast tells you what you'll be breathing at 7 am tomorrow — which is what actually matters when you're deciding when to run, ventilate the house or take the kids outside.
How Hyperlocal Weather forecasts AQI
Hyperlocal Weather builds its AQI forecast for your exact coordinates, drawing on the same engine that powers the rest of the app — Foreca, Apple WeatherKit and real weather-station observations. You get the live index with its main pollutant, an hourly chart covering the next 84 hours and a 3-day outlook, all inside a full weather app rather than a single-purpose AQI app. You can also turn on custom weather notifications to be alerted when the air quality at your location changes.
Who benefits most from an AQI forecast?
- People with asthma or heart conditions who need to time medication, masks or indoor days.
- Parents and carers deciding when children or elderly relatives should be outdoors.
- Runners and cyclists choosing the cleanest training window of the day.
- Anyone near wildfire smoke or city smog watching for the air to clear.
Air quality is one piece of the day's plan — combine it with the hourly forecast graph for rain and wind, or check climate normals to see how today compares with a typical day at your location.
Air quality forecast questions
How far ahead does the air quality forecast go?
Hyperlocal Weather forecasts AQI hour by hour for the next 84 hours — three and a half days — as a colour-coded bar chart, plus a simple 3-day outlook. So instead of only seeing the air quality right now, you can plan runs, bike commutes and outdoor time around the cleaner hours ahead.
Does the app tell me which pollutant is the problem?
Yes. Alongside the AQI number and its category (such as 32 Good), the app names the main pollutant driving the index — for example PM2.5 — so you know whether you're dealing with fine particles, ozone or something else.
Is there health advice for asthma and other sensitive groups?
Yes. Every reading comes with two sets of health recommendations: one for the general population and one for sensitive groups — people with asthma or heart conditions, the elderly and children — so each member of your household knows what today's air means for them.
Can I get a notification when air quality changes?
Yes. Hyperlocal Weather supports optional custom notifications for air quality, so you can be alerted when the AQI at your location changes — useful during pollen season, wildfire smoke events or city smog episodes. The app is free on iPhone and Android and works worldwide.
