What happens in extreme heat or bad weather, and when is a pennant game abandoned?

These rules are for Open Gender Saturday and Thursday pennant. Women's Tuesday and Friday pennant have their own conditions.

Rescheduling for forecast heat. If the 4.30pm Perth BOM forecast is 35 degrees or above, clubs can agree to change a start time. For Thursday, the forecast is checked on the Monday, clubs can pick any time on Thursday, and both must email Bowls WA by 5.30pm Wednesday. For Saturday it is the Wednesday forecast, the new time can be Friday evening or Saturday before 3.30pm (not Sunday), and the email goes by 5.30pm Friday. If a club doesn't want to change, the scheduled time stands.

General abandonment. If the forecast is 41 degrees or over, all pennant games are cancelled at 5.00pm the day before, announced on the Bowls WA website. Bowls WA can also call one for other extreme conditions. Points are shared equally.

On the day (Umpire of the Day, using the club's designated BOM weather station).

• At 38 degrees up to 40 degrees: play starts as scheduled. After 30 minutes of play, the umpire calls players off at the end of each rink's current end for a 10-minute rest, then play resumes for 30 minutes, repeating while the temperature stays at 38 or above. A side that refuses to leave or return is warned, then forfeited.
• At 40 degrees and over: play is deferred. A game not started within 60 minutes of the agreed start is abandoned.

Other weather. If the host club's greens are closed before play, the game is abandoned and points are shared equally. If play is delayed, the game can't be abandoned until 60 minutes of cumulative delay has passed unless conditions make play highly unlikely, and after 60 minutes it must be abandoned. If the prescribed number of ends (56 for four-team sides, 42 for three-team sides) was played, the game counts as completed. Otherwise it's incomplete and points are shared equally.
