Just one week later on the 8th of June, the weather conditions for a Marathon were a lot more favourable.
The graph above shows the temperature recorded on an elevated site near Cork city one week apart. The actual temperature in the city may have been a bit higher, especially in sheltered spots.
On Marathon day, the temperature was already 16 degrees by the time of the start of the race and just 2 hours later had climbed above 21 degrees C. In all likelyhood, there were spots along the course that were close to 25 deg C especially in the afternoon.
Compare that to the weather 1 week later when it was overcast all day with a wind from the North-East. At 9am, it was only 12 deg C and it struggled to get to 15 deg C in the afternoon.
For the last 3 years, 2007 and 2009 were above 20 deg C and 2008 was not too far behind. The Cork Marathon seems to be getting a reputation as a Marathon at the wrong time of year. However, what if the Marathon had been on the 8th?........imagine the difference that 10 deg C would make.
