Or is it a myth?
There isn't a cloud in the sky and the weather is gorgeous. Good news for most us, but not for the thousands of students that will be cooped up in exam halls for the next couple of weeks.
I sat the Junior Leaving Cert in 2004 and the Leaving Cert two years later, and from memory I can distinctly remember the sun brazenly hanging above the skyline of Mohill Co. Leitrim for the duration of those exams, taunting those furiously writing, stressing and sweating in the exam halls below.
The weather does seem to improve around the time of the Leaving Cert, especially during the intense first three days which feature both English papers, an Irish paper and a Mathematics one.
Of course, the Leaving Cert's allotted space on the calendar in early June would probably explain the reasonably good weather. Then again this is Ireland, where summer does not necessarily translate into summer weather.
So is it a myth that the Leaving Cert is a period of sweetness and light from a climate perspective?
Generally rain has stayed away during the opening salvos of the Leaving Cert in the past decade.
In 2005, 2006, 2007, 2009 and 2010, there was little to no precipitation during the first three days of the exams, while rainfall was limited in 2004 and 2011.
However last year was far from great weather-wise during the first three days, with precipitation at its highest point in comparison to the rest of the decade and less sunshine that month than an average June.
But temperatures in 2012 were pretty good, especially in comparison to 2008 and 2011 which were below the June average of about 14°C.
