Long Range Forecasts

The long range weather forecasters do not have a very good accuracy rate - long range predictions are notoriously problematical.  But there are a few published forecasts for the coming summer... 

UK Met Office

"The most likely scenario for the summer is above average temperatures and slightly below normal rainfall." 

Weather Action

"We predict a cooler summer." 

London Weather Index

"This summer will be the hottest summer for five years, with a greater than 50% chance of a mini-drought." 

British Weather Services

"2001 will see a hot summer."

University College London, Benfield Greig Hazard Research Centre

"Coming spring 2001 Central England Temperature is expected to be close to the 1971-2000 average. Forecast: 8.59 +/-0.56 C; Average 1971-2000: 8.55 +/-0.78 C."


Whatever the weather, join us for a fun party...and if it does rain, we'll stay in the drinks tent, taunt the rowing crews and organise a wet T-shirt competition.
