Cloudbase Weather
Forecasts, Radar & Air Quality
Free · Designed for iPad. Not verified for macOS.
Forecasts built from the weather models that scored best on past weather, detail by detail, near our four trained airports. See every score in the app. Free METAR widget.
Cloudbase builds your forecast from the weather models that scored best, chosen separately for each forecast detail and each day ahead. Within 250 km of Edmonton, Calgary, Grande Prairie and Ontario (California), each choice that could be scored was first or tied against GFS and the other models Cloudbase can serve there, on our own scoring of 19 months of past weather. Those scores come from the same history used to make the choices, and the app's accuracy pages show every one.
No account required. No ads. Just weather.
— FORECAST & RADAR —
Detailed daily and hourly forecasts with temperature, precipitation, wind, pressure, visibility, and cloud cover — for Canada and the United States. Interactive radar with animated playback and immersive full-screen mode, automatically centered on your location.
— AIR QUALITY —
Real-time AQI with pollutant breakdowns — PM2.5, ozone, smoke, and more — so you know what you're actually breathing before you head outside. Coverage across Canada and the US.
— HOME SCREEN WIDGETS —
A large collection of beautifully designed widgets for your home screen and lock screen. Choose from minimalist, glassmorphic, terminal-style, radial, chart-based, and more. The free METAR widget shows live aviation weather right from your home screen — no app needed.
Each widget can follow the app's current location or be pinned to any city you choose.
— AVIATION WEATHER —
For pilots and weather enthusiasts: live METARs and TAFs for nearby stations, VFR/MVFR/IFR/LIFR flight category indicators, winds aloft, and 24 hours of historical METAR observations — all in one dedicated tab. Covers airports and aerodromes across Canada and the US.
— ALWAYS READY —
Background refresh keeps widget data and offline forecasts current even when the app is closed. Severe weather notifications deliver local alerts the moment conditions change.
— MORE —
• Apple Spotlight integration — search any city from your home screen
• Share extension — open Cloudbase directly from Safari
• Multi-location search with instant switching
• Fully configurable units: metric, imperial, or mixed
• Optimized for iPhone and iPad
• Dark mode throughout
Cloudbase is built for anyone in Canada or the US who takes the weather seriously — whether you're planning a weekend hike, tracking a storm, or checking conditions before a flight.
more Cold Lake joins the forecast. Places nearer Cold Lake than Edmonton, such as Bonnyville, St. Paul, Lac La Biche and Lloydminster, now get forecasts tuned for Cold Lake in the app and in the widgets.
Edmonton, Calgary and Grande Prairie forecasts are slightly more accurate, now that the four Alberta airports share what they learn.
1.8.16 3d ago
Radar widget: rain, snow, mixed precipitation and freezing rain now show in their own colours, the same as the radar map in the app and on the website. A new "Show precipitation type" switch in Map Options turns these colours on or off for both the map and the widget.
Map Options now has a colour key: the precipitation colours, lightning by strike age, and warning areas by severity.
Every weather widget now shows the time it was last updated. Tapping the Radar widget now always opens Radar, even if the app had been closed for a while.
Radar widget: the map under the radar now appears reliably, including after you travel.
1.8.15 4d ago
Ottawa and Toronto now get Cloudbase's own trained forecasts in the app and in widgets. Rain and snow amounts now always add up to the day's total, and widgets show both amounts on any day with rain and snow, freezing-rain and storm days included.
Radar: the time bar now follows your finger, blending smoothly between radar pictures as you swipe. The 1-hour radar forecast shows in amber on the bar, and a new switch in Map Options turns it on or off. In the US, Radar widgets now show the same radar picture as the app. Weather widgets wait briefly for a refresh already in progress, so they show the newest forecast more often.
Widgets now show the name of the place you're in, instead of "Current Location", after you move with the app closed.
1.8.14 6d ago
Weather widgets can now pick up new cities without an app update, starting with Vancouver and Victoria. Improves the diagnostic information the app records about weather widgets.
1.8.12 Oct 24
What’s New in 1.8.11

Thank you for using Cloudbase.
1.8.11 Oct 24
What's New in 1.8.10:
• The Radar widget is much lighter on memory, so it no longer stays on "Loading radar…" on iPhone. Please remove your Radar widget and add it again once after updating.
• Widgets now show each day's steady wind, and add the gust only on gusty days (written like "30G55"), as the app does.
• The Classic widget names freezing rain, freezing drizzle and mixed days instead of "Partly Cloudy".
• Updated forecast recipes: Ontario, California now counts timed rain reports, which changed ten of its recipes.
• The chance of precipitation no longer goes blank when one weather model has a short outage.
Thank you for using Cloudbase.
1.8.10 Oct 23
What's New in 1.8.9:

• Improved forecast-widget reliability and consistency
Thank you for using Cloudbase.
1.8.1 Jul 29
What's New in 1.8.0:

1.7.5 Jun 18
Fixed blank/white widget bug caused by an invalid temp endpoint URL. Improved widget reliability when forecast data is temporarily unavailable. Fixed edge case where aviation widgets could show blank stations. Better handling of empty forecast responses to prevent blank widgets.
1.7.4 Jun 14
• Radar now opens directly to the map with a native "Show Controls" pill — tap it to open a full-height options panel for lightning, warning polygons, and display quality, then swipe down to dismiss.
• Tighter spacing on the Overview page so weather warnings sit closer to the search bar with consistent gaps.
• Fixed tab switching and radar routing so Cloudbase is less likely to jump back to another section after you choose where to go.

• Fixed cases where Home Screen widgets could appear blank, all-white, or stuck in an unclear loading state when forecast data was missing or still refreshing.
• Improved widget forecast accuracy by preserving Cloudbase's real forecast units and only showing gust values when gust data is actually available.
