A poor year for English grapes?

We are all putting on brave faces this year but we have to admit that so far it has been a horrible year for English grapes.

Just to recap – After a very warm, dry March (the third warmest on record), we had the coldest (for 23 years) and wettest April on record. May was cold then very warm so was average overall, but better in the north than the south. June turned out to be the wettest dullest month on record. June is a key month for grape growers, the vines normally flower in June but with 145mm of rain, which is twice the normal average, any flowers would have been washed off and it was cold and windy as well. So April – June 2012 turned out to be the wettest period since records began in 1910.

Hosepipe bans were abandoned as reservoirs were replenished and July wasn’t much better. As temperatures dipped and the heating was turned on people were asking whether we would ever have a summer. Luckily, the end of July and early August has turned out to be a little warmer.

So this year has not followed the trend of recent years for hotter and hotter English summers. However, as my kids always point out ‘it’s not global warming but climate change, Dad.’ And the statistics back that up.

Did you know that in June 2012 the average surface temperatures in the northern hemisphere hit an all-time high, 1.3°C above average!

What’s more globally the average land surface temperature for June 2012 was also the all-time highest on record, at 1.07°C above average. The global average surface temperature for January–June 2012 was the 11th warmest on record, at 0.52°C above the 20th century average.

The trouble is that whilst Austria basked in record 37.7°C heat and experienced its warmest June since records began 250 years ago, the average UK temperature was 0.3°C (0.5°F) below the 1971–2000 average, making this the coolest June since 1991.

You won’t have to tell the Americans this. July 2012 was the hottest July in north America since their records began. And the Greenland ice sheet melted at such an alarming pace that scientists couldn’t believe the data.

According to the NOAA what they call an ‘anomaly’ has not just affected Great Britain but the whole of northern Europe. Norway had one of the coldest Junes on record and northern France was also suffered.

At Rathfinny the biggest problem has been the wind. You normally get the odd summer storm, which whistles up the English Channel. Remember the Fastnet yacht races, which were devastated in 1979 and 2007? This year we had several storms and the winds seem to have been unrelenting. This is not great news for young vines, which stop growing when the wind picks-up. We planted trees as wind breaks in 2010 but they are still too immature to have any effect.

So our vines are still growing and are doing okay but should be a lot bigger. However, I feel sorry for other more established English vineyards that are likely to have very poor year and low crop yields. Of course we could all be saved by a scorching August and September. But the message is to look to the long term, the UK is still a beneficiary of ‘climate change’ and it is likely that next year will follow the trend of the last twenty years and be another scorcher.

In the meantime with a lot of hard work led by Cameron, David, Felix and Ian the trellising work is now nearly complete. We have a vineyard…
