Installed on 1.7, haven't tried it with 2.5. Works great for a simple weather module, easy to custimize. Looks great on a light colored template, but looks bad on a dark template.

Works fine for me, except for two issues. Firstly, it uses "floor" instead of "round" for the celcius to fahrenheit calculations, so 2.9C is displayed as 2C (not a big issue, and easily fixed with a quick hack). More importantly, it has a limited set of icons, so "sunny", "mostly sunny" and "partly sunny" are all shown with a blazing sun icon, which is pretty misleading.

Would be better if it had proper timezone support for my locality, Australia ACST (UTC+9:30)

ACDT (UTC+10:30) etc.

When I opt to use Google weather feed, the icons don't show and there is no option to use Google's default icons.

The Backend user interface would be more friendly if it were to use Joomlas default styling instead of the orange sliding DIV's.

I don't understand why you can not forecast more than 2 days when using Yahoo Weather.

Apart from the above mentioned it has great functionality, easy to implement and looks clean from the front end.

Beautiful, easy to setup and to install. Work in a "little" town in the west of France!



Unfortunately, the support is not free, even for one question…. I hope it will in the future!



Thanks

Weather data through yahoo is accurate

Clean look, great icons, nice feel

Good customization options.

Thanks!!



(tried many other extensions but they didn't come close to matching this one)

Does exactly what it says. Easy setup and support for multiple languages ​​(including PT-BR). I'm using on my site and recommend it to everyone. Perfect.

I like it but I experienced that my site got a loooooong load time and a nasty PHP XML error because the weather service was down for some hours. I got my site up and running normal again when I disabled the weather module (using Joomla 1.5 and GK1 v.1.2). So kind of weather online service check is needed in order to use it fully on a professional site :-) So for now I have disabled it, but I loved it before I knew about the missing weather service online check.

Works well for "famous" cities like London, Paris etc.



But for anywhere else it's very hard to know what to put for Location and you'll get "An error occured - you set wrong location or data for your location are unavailable".



Supposedly it uses both (or either?) Google and Yahoo weather. But it's not immediately apparent if this can be configured or how, or which one it is using at any given time.



The location I want (Yanbu, Saudi Arabia) shows up in both Google and Yahoo weather, but I've tried all possible combinations of names and spellings and can't get anything but the error message. Perhaps with clearer documentation it is simple.



Click on the "need you help" link and you'll be invited to pay between 40 and 199 Euros.



I'm not too impressed.

Problem with certain countries (Lecce, Gallipoli, Otranto ....)

I downloaded the extension from their Gavick website the version 1.1.0 which the website says was last updated Jan 25, 2011. However, upon installation, the backend says the extension was actually Jan 31, 2010 update.



The extension itself looks nice. Unfortunately, the latitude, longitude, and timezone settings don't work. Supposedly, based on these settings the displayed icons will alternately show either a sun or a moon depending on the time of the day for these settings. However, in my case, the icons appear stuck as a moon 24 hours a day based on the latitude/longitude settings i obtained from Google Maps. If you change the values to null, the icons are stuck to a sun all day long for 24 hours. Changing timezone values don't have any effect.



Also, the weather forecast displayed seems to be less accurate compared to The Weather Underground. The other day, it was raining heavily here in my place, but the forecast says "Partly Cloudy", while The Weather Underground accurately says "Rainy".
