Racing Queensland stewards have an emergency plan in place should predicted temperatures eventuate at the Gold Coast and Ipswich race meetings on Saturday.

Temperatures as high as 45C are forecast for Ipswich, where the second south-east Queensland meeting will be held on Saturday.

The prediction is for lower temperatures in the mid to high 30C on the Gold Coast for the Goldmarket meeting.

However, stewards will be well prepared to make certain both horses and jockeys are protected at both meetings.

Chief steward Wade Birch said stewards would use a water bulb to check the humidity remained at an acceptable level.

"It isn't dry heat that we worry about it is the humidity. Should it reach an unacceptable level we would suspend racing until it was safe," he said.

Birch said extra water and hoses as well as buckets of ice would be provided if needed.

A review would be undertaken on Saturday morning and if necessary, horses would be allowed to arrive on course later and also have a delayed entry into the mounting enclosure.
