Big Weather

Big Weather at a glance

Big Weather is a macOS menu bar weather app from Urtti Apps Oy. It keeps the current temperature in the menu bar and opens a forecast panel with the days ahead represented as a single temperature-and-rain curve, so users can inspect conditions without working through a conventional table.

The app supports current-location forecasts and searches for cities worldwide, with saved places for switching between locations. The free version covers core short-range weather information; Premium expands the forecast horizon and adds features including official warnings, on-device AI summaries on compatible Macs, Apple's weather data, more frequent updates, and Family Sharing.

Features

Menu bar weather

The current temperature stays visible in the macOS menu bar, with conditions available from the same compact interface.

Interactive forecast curve

A curve combines temperature and rain across the next 48 hours in the free version, or up to 10 days with Premium. Move the cursor along it to inspect individual hours.

Forecast details and layouts

The panel includes UV, wind, pressure, humidity, and multi-day forecast information; a plain-text layout is available instead of the chart.

Locations and saved places

Use your current location or search for any city in the world, then save places for quick switching.

On-device AI insights

Premium can display a short daily forecast statement and a weekly summary. On compatible Macs, Apple Intelligence generates these locally rather than sending the location to an AI service.

Official weather warnings

Premium displays official warnings word for word for covered locations in the US, Canada, Mexico, and Europe, with markers on affected days.

Use cases

  • Checking weather during desktop work

    Keep the current temperature visible while working and open the panel only when you need a more detailed look at the coming hours.

  • Planning around changing conditions

    Scrub through the curve to identify when rain or temperature changes occur, without interpreting a dense hourly table.

  • Comparing multiple locations

    Save a home location, travel destination, or other frequently checked city and switch between them from the app.

  • Adapting the display

    Use the plain-text layout, unit controls, and light or dark appearance to make the forecast easier to read in a preferred format.

  • Monitoring significant weather

    With Premium, review official warnings and locally generated AI summaries when deciding how to approach a day or week of weather.

Pros and Cons

Pros

  • The temperature and conditions are accessible directly from the menu bar.
  • The forecast curve provides hour-by-hour temperature and rain information in a visual format.

  • Users can choose chart or plain-text presentation, light or dark appearance, and Celsius, Fahrenheit, or both.
  • Premium includes official weather warnings and optional on-device AI summaries on supported Macs.

Cons

  • It is Mac-only and requires macOS 15.2 or later.
  • AI insights have additional requirements: Premium, macOS 27, and a Mac with Apple Intelligence.
  • The site does not document integrations or team-oriented collaboration features.

FAQ

How do I install Big Weather?

Big Weather is available from the Mac App Store and requires macOS 15.2 or later. It runs in the macOS menu bar and opens its forecast panel when selected.

What location and privacy options does Big Weather provide?

The app can use your current location or any city in the world. Your location is sent to the weather service to retrieve a forecast; the site says Big Weather does not keep a user profile and has no ads.

What is included in the free version and Premium?

The free version shows 48 hours of temperature and rain, a three-day forecast, UV for today and tomorrow, wind, pressure, and humidity. Premium extends the hourly forecast to 10 days and adds AI insights, official weather warnings, Apple's weather data, more frequent updates, and Family Sharing.

Why might AI insights not be available?

AI insights require Premium, macOS 27, and a Mac with Apple Intelligence. Apple Intelligence writes the summaries on the Mac; other Macs receive the regular summary instead.

Can I use Premium on more than one Mac?

Premium can be used across your Macs with Family Sharing. The site does not describe team workspaces or business collaboration features.
