Where did Sydney's summer go?
About one week after western suburbs endured its hottest four-day heatwave in 37 years; Sydney is likely to be heading for it coolest February period in more than 50 years. The city is in the middle of at least a week where the temperature stays below 25 degrees. The likely number of days is nine, with next Wednesday being the first day warmer than 25 since last Sunday. This will make it the longest February stretch below 25 degrees since the 1950s. Sydney also had nine days in-a-row below 25 in February 1953 and eight in 1996. The last time there was a longer stretch was in 1950 when there were 13. The extraordinary turnaround from last week's heat is a due to plenty of cloud and showers being blown in by persistent onshore southeasterly winds. When will the summer warmth return? The middle of next week as winds turn warmer northeasterly, but it will only be brief, just a few days. The city is likely to reach the high 20s, possibly the low 30s, but a cooler change late next week will put an end to that warmth. Western suburbs will hit the low-to-mid 30s before the change. Frequent cooler changes for the rest of the month will the chances small of a prolonged heatwave.
