The first day of the Royal Welsh Show got underway today.
Crowds of more than 50,000 people are expected every day at the four-day agricultural events.
Organisers have been told by public health bodies to prepare for the extreme heat.
They have spent more than £50,000 on extra fans and ventilation in livestock sheds to keep the approximate 8,000 animals as cool as possible while extra water will be available.
An RWAS spokeswoman said: “Numerous provisions are also being made within the livestock section. Additional water will be available, and fans have been installed in all the livestock buildings with new upgraded fans in the most vulnerable areas.
“Arrival times for livestock have been amended in order to welcome stock in the early morning and late evenings, to avoid queues at the hottest times of the day.
“Temperatures in the livestock buildings will be monitored continuously, to support real-time decisions. Consideration will also be given to class timings, which can be changed if necessary.”
