Temperatures will build again later this week and over the coming weekend, likely peaking on Sunday and Monday.

Some exceptionally high temperatures are possible and cumulative effects of warm nights and hot days are expected to bring widespread impacts to people and infrastructure.

This period of hot weather is expected to continue into the early part of next week, hence an update extending this warning into Monday is likely.

What to expect

  • Substantial changes in working practices and daily routines likely to be required
  • Significantly more people are likely to visit coastal areas, lakes and rivers leading to increased risk of water safety incidents
