Adelaide is about finally warming above average, breaking its longest run of February days below 25 degrees in decades. There were signs of the warmth arriving yesterday. It became the warmest day in more than a week, but it was still five degrees below average, only reaching 24 degrees. Today the city looks like reaching 30 degrees for only the second time this month. Normally in February there are 12 or 13 days this warm, so its been a significantly cool end to summer. For those who like the heat, there will be a brief burst of northerly winds on Tuesday and Wednesday, when the temperature will nudge the mid 30s, the hottest its been in more than two weeks. Thursday and Friday will be a little cooler, but still near 30 degrees, before it heats up on the weekend. Both Saturday and Sunday should get to the low-to-mid 30s before a stronger cooler change on Monday, which looks like heralding a return to cooler days. Since the first weekend of the month, Adelaide and much of SA has been stuck in a spell of southerly winds, a result of a near-stationarty high over the Bight. It has failed to warm to 25 degrees in each of the last eight days, which makes it the longest run of days this cool in February since 1990. In that February there were eight days in a row cooler than 24 degrees. A similar feat occurred in 1980, also eight consecutive days below 25 degrees. The last time there was a longer run of sub-25-degree days in February was in 1972, 40 years ago. In that February there were 10 in a row below 24 degrees. February is typically the warmest time of the year with a long-term average maximum of 29.4 degrees.
