Earth's global average sea surface temperature has reached record-breaking high levels over the past week as El Niño gains strength in the Pacific Ocean.

Christchurch has seen its hottest June temperature on record, hitting 25.1 C at 2pm today, as northwesterly winds buffet the South Island and lower North Island.

The European climate service Copernicus says the world's oceans have reached their hottest temperature on record.

On February 3, 1947, the small village of Snag in Yukon, Canada, experienced the coldest temperature ever officially recorded in the country and all of North America, reaching an astonishing −63°C (−81.4°F). To put this extreme cold into perspective, it is roughly equivalent to the average surface temperature of Mars. The temperature was so severe that the alcohol in thermometers fell below the measurable scale, requiring the weather observer, Gordon Toole, to manually mark the thermometer so it could be sent to Toronto for precise calibration. The air, dense and still due to the extreme cold, carried sounds over extraordinary distances; dogs barking from over 6 kilometers away could be clearly heard. The freezing conditions caused exhaled breath to solidify instantly, producing a hissing sound and forming fine white powder in the air. People walking outside left visible streaks of frozen breath that lingered for minutes. The Snag weather station operated from 1943 to 1966, and this record has remained unbroken since. The name 'Snag' originates from the Klondike gold rush era, referring to submerged tree trunks that posed hazards to boats navigating the silty waters nearby.
