The Forecast Channel allows weather reports and forecasts to be downloaded onto the console from the Internet via the WiiConnect24 service. The Forecast Channel displays a view of the Earth as a globe (courtesy of NASA), with which users can view weather in other regions. The user can also spin the globe. When fully zoomed out, an accurate star map is visible in the background (the Big Dipper and the constellation Orion are easily recognizable, for example). The Forecast Channel features include the current forecast, the UV index, today's overall forecast, tomorrow's forecast, a 5-day forecast (only for the selected country), and a laundry check (Japan only). Certain games (like Madden NFL 07 and NiGHTS: Journey of Dreams) can use the Forecast Channel to simulate weather conditions depending on the player's region.

Emulation Information

Shut Down

This channel's original online functionality has been shut down as of June 28, 2013 and works in neither Dolphin or on Wii hardware.

WiiConnect24 Revival Services

Both RiiConnect24 and WiiLink can provide WiiConnect24 support in Dolphin through a variety of means. As of 5.0-19724, users can automatically redirect to use the WiiLink service in Dolphin without needing to patch channels or manually download VFF files outside of the emulator. This can be enabled in `Options → Configuration → Wii` under the "Enable WiiConnect24 via WiiLink" setting.

Stale VFF Files

As of 5.0-17613, Dolphin now supports downloading VFF files from WiiConnect24 services just like a real Wii. This allows users to connect to services like RiiConnect24 and WiiLink without the need for a VFF Downloader. Users that have previous used a VFF downloader may need to delete old VFF files before the new services will work. This is because VFF files downloaded with some revisions of the VFF downloader have been hacked to never expire, so the emulated system will never attempt to download new ones.

Support on Older Dolphin Versions

Prior to 5.0-17613 some WiiConnect24 channels can still be made to work through the use of a VFF Downloader. There is a program that RiiConnect24 made as a workaround to download the latest weather data regularly. See this tutorial for more details.

Missing Game List Banner

Certain Wii apps and homebrew apps never create savefiles that are handled by the emulated Wii's internal savefile lists, so no banners are ever generated for them in Dolphin.

Prototype channel animation

Under various circumstances, including to have Wii Menu installed → install Forecast Channel as a WAD to NAND → remove Forecast Channel from NAND again → open anything else directly from Dolphin → return to the Wii Menu, prototype logos are shown as if Forecast Channel thinks it's on System Menu 2.0 from the North American Wii launch in 2006, and will also show an Update prompt that for users of System Menu 4.3x can't update anything anyway. The rest of Dolphin will work as normal.

The prototype is often referred to as "Forecast Channel dummy", and plays a special "3 tone with fadeout" jingle when clicking on it in Wii Menu.


Wii Menu Crashes Loading Forecast Channel's Banner

The Wii Menu crashes when loading Forecast Channel's banner. This is a problem with the Wii Menu; more info here. Resolved with 5.0-3147.


This channel does not need non-default settings to run properly.

5.0-2877 Windows 7 Intel Celeron G1610 @2.6 GHz Intel HD Graphics Well, it started, but since the service was shut down i don't know how many stars should i put to it. It ran the same on my wii. "Unable to get latest information." EblfIYH
5.0-5033 macOS Intel Core i5 @ 2.7 GHz Intel Iris Pro If you copy over the VFF from a Wii that has RiiConnect24, it works perfectly. Larsenv
5.0-21088 Windows 11 AMD Ryzen 5 3600 @ 3.6 GHz NVIDIA GeForce RTX 3060 Works perfectly by running "Perform Online System Update" → "Europe", turning on "Enable WiiConnect24 via WiiLink", then "Load Wii System Menu 4.3E", and opening Forecast Channel from there. The default country with this method is Switzerland, which would have to be changed in the System Menu settings. DandelionSprout
