One of the big yearly holiday events for Finland is this weekend, Juhannus, also known as midsummer. Unfortunately, the weather has been anything but summery for the past week and a half. After the 4th coldest day of the past 6 years, temperatures plummeted on Wednesday morning to -1.4C. This is the coldest in at least the last 6 years. It's hard to find exact records, but some websites indicate the lowest ever recorded June temperature in Jyväskylä is around -3C.
Unlike a day earlier, Wednesday managed to climb above 10C. It actually got to 15.1C during the day. Thursday and yesterday, however, failed to reach that mark with 14.3C and 12.7C respectively.

Surprisingly (or then maybe it's not that surprising if you know Finland), all midsummer weekends in the past 6 years haven't been that warm. Not one day in all those weekends since 2009 has measured above 25C, the highest being 23.4C on June 25 in 2010. Based on current forecasts, the midsummer weekend this year will have the lowest average temperature.
While Jyväskylä struggles to climb above 15C, today Sydney Airport made it 3 straight days above 20C for the 4th time this month. This is quite unusual for June. It occurred twice in June last year, but not once between 2009 and 2012. Years before 2009 also show few, if any, occurrences. Yesterday's 22.3C was the second warmest maximum of the month so far. It got to 20.3C today.
The warmer temperatures have been accompanied by drier conditions also. Today was the 5th straight day without rain, the longest stretch since late May.
At this point, Sydney Airport is on track to record one of its warmest Junes on record.
