The Environment Agency is issuing a flood warning warning for four areas - three in south east England and one in Anglia – and is monitoring 41 areas for possible flooding.
The Suffolk Show, which receives 90,000 visitors a year, was forced to cancel the second day of its event on 8 June.
Staging the show typically costs £1.4m. Organiser Suffolk Agricultural Association has underwritten the event by £500,000 rather than the usual figure of approximately £100,000. It said in a statement that "events of this nature are difficult to insure against such issues as severe weather."
Charlbury Riverside Festival in Oxfordshire was scheduled for this weekend (16 -17 June) but has been postponed until later in the year due to the weather conditions.
The free music festival attracted 5,000 people last year and had more than 30 bands in the lineup for this year’s event.
Kathryn Custance, an organiser of the festival, told Event: "The particular problem with our event is that we’re on a field that’s surrounded by river, it’s technically an island. It’s not flooded now but we don’t want it to flood before the weekend and for the Environment Agency or the council to shut the festival down for us."
For the first time since World War I, the weather also led to the cancellation of Durham Regatta. The rowing competition was planning to hold its 179th event from 9 -10 June. Nigel van Zwanenberg, chairman of the regatta, said: "This is a ‘first’ that none of us wanted. As far as anyone can tell, and we have one member who has been to 59 Durham regattas, not even one day of the regatta has ever been lost before. Indeed, it previously took a World War to prevent the regatta from taking place. The weather for a June weekend was truly awful."
A medieval fayre planned for Saturday (16 June) at Winterbourne Medieval Barn in south Gloucestershire has also been cancelled. Organisers said in a statement: "After much heart searching, the trustees and organisers have regrettably decided to cancel this event owing to the prevailing weather conditions.
"We apologise to those who were so looking forward to this event and hope they will continue their enthusiastic support of our future events."
