The league and the LTA take the safety and well being of players, spectators and officials extremely seriously.
The LTA has introduced an Extreme Heat Policy in addition to the Adverse Weather Policy to provide guidance to players and tournament officials during a heat wave. This new policy is inline with those of the ITF, WTA and other leading federations. Any wheelchair competitions should follow the ITF Wheelchair Circuit Regulations.
Heat Stress Index
The Heat Stress Index Chart provides a general guideline for assessing the potential severity of heat stress. Individual reactions to heat will differ. It should be remembered that heat illness can occur at lower temperatures than indicated and susceptibility increases in the very young and elderly. Exposure to direct sunshine can also increase the Heat Stress Index.

Please refer to the LTA Extreme Heat Policy for full details.
