Which address should you search to check the weather in Antarctica and the North Pole on your mobile phone?

The closest to Antarctica is Ushuaia in Argentina, which can only be a rough reference. After crossing the Drake Passage, the weather is difficult to predict, and there are currently no weather reports there on my mobile phone. When I go to Antarctica, I get on the boat and listen to the instructions on the boat. He will make arrangements according to the weather conditions.

Arctic is the northernmost city in Russia, I don’t remember.
