UP to 35,000 people are expected to attend the Battle of Evesham and medieval festival today.
Mick Hurst, the director of the event, said: "Yesterday, we had a fantastic turnout of people, probably due to the weather.
"I go and take photos of the audience for my records and there was a massive audience.
"If we get the same turnout today we should be reaching probably 35,000 people.
"All of the re-enactors loved it, they think Evesham is a wonderful place to come and perform their hobby.
"So, the weather wasn't too hot yesterday while they were running around in nine stone of armour and padded quilts underneath the armour.
"The beer tent did really well, all the food and drink traders are happy bunnies.
"We had to close the car park at 1 pm yesterday because it was full and that was 550 cars.

"People drifted in and out all day so we sporadically reopened it.
"We signposted people to the car park in town when it was full. We have marshalls who helped people with that."
The Battle of Lewes re-enactment took place today at 12 pm and the Battle of Evesham re-enactment will be at 4 pm.
Other stalls with refreshments, medieval food and crafts and much more will be open throughout the day.
While the warm weather has been brilliant for attracting people to the outdoor event, some of the live history performers expressed concern about the heat.
Chris Binns said: "The battle later will be interesting with it being this hot.

"Some of the hardcore members have been walking around in their chainmail all day though, I don't know how they're doing it."
Martin Latham, who was participating in the re-enactment, said: "We did a re-enactment in Tewkesbury in around 30-degree heat once and people were fainting.
"People have fainted before so it might happen today, it depends on how hydrated everyone is."
The Battle of Evesham, was one of the two main battles of 13th century England's Second Barons' War.
It marked the defeat of Simon de Montfort, Earl of Leicester, and the rebellious barons by the future King Edward I, who led the forces of his father, King Henry III.
It took place on August 4, 1265, near Evesham.
