Perth's current warm streak is not likely to end until at least Saturday April 2nd, by then it will have run a record 13 days. Today is the city's third consecutive day of heating to 30 degrees or hotter and it looks like being well into April before it fails to reach 30. This will make it the longest warm spell this deep into autumn in more than 130 yeas of records. Perth and much of the west coast has been under the influence of easterly winds, gaining heat as they blow across the land. Low pressure troughs near the west coast have caused these easterlies to become fresh at times and hold out cooling sea breezes. The interior has been kept warm with help from cold fronts staying well south of Western Australia. A similar set-up occurred last March when Perth had eight consecutive days of 30 degrees or hotter, including one 35-degree day and one 40. The longest run of 30-degree days this late in autumn is 12 days, set in 1998, running from March 24th to April 4th. Inland parts have had longer streaks this late in the season. In 1995 Perth airport recorded 19 consecutive 30-degree days, ending March 28th. As for rain, the city may extend its dry spell to beyond two months.
