Incorrect weather in Southern hemisphere

I've notice flying in South America, the weather displayed is sometimes incorrect.
I'm currently at 34'30 south and 58 west and latest weather was from DIAP in Abidjan! a few minutes later, the corect weather showed up for SADF. I then asked for a metar for SAGA and again got the weather for DIAP.
I've seen this a couple of times before, but just figured it was a glitch, which apparently it is...
