Showers, M4 Delays and Train Changes

Wake Up Sydney with Johnny Rocket brings you the latest weather, traffic and train updates for Friday 21 August 2026, helping Sydney start the day informed and prepared. Today is shaping up as a mild and showery day across the city before a brighter, sunnier weekend arrives. Sydney CBD is currently 16.7°C and heading for a top of 23°C with showers expected, while Parramatta is starting cooler at 13.6°C and reaching 22°C with a shower or two. Bondi is sitting at 17.3°C, with a forecast top of 21°C and showers along the coast. On the roads, the key issue is at Eastern Creek, where a truck breakdown is affecting the M4 Motorway westbound near the Brabham Drive underpass. The shoulder is impacted and the speed limit has been reduced to 40 km/h, so westbound drivers should allow extra travel time and take care near recovery crews. Elsewhere across Sydney, traffic is moving well. For public transport, it is the final day of Blue Mountains Line trackwork. Buses are replacing trains between Lithgow and Mount Victoria, with some buses towards Mount Victoria leaving up to 15 minutes earlier than the usual train timetable. Trains continue between Mount Victoria and Central on a changed timetable, and Bathurst services are also running to adjusted schedules. Passengers connecting with NSW TrainLink Regional Coaches at Lithgow should confirm departure times by calling 132 232. The rest of the Sydney train network is running smoothly.
