Best time to cross the Causeway, hour by hour
We keep a record of every jam score at Woodlands. These charts show the average score for each hour of the day, built only from hours when real people reported the queue. Use them to pick a better time to go.
The short answer
From 71 days of reports at Woodlands (2026-08-03 to 2026-10-12):
- SG → JB on weekdays, cars: busiest around 7pm (63/100), calmest around 3pm (27/100).
- SG → JB on weekdays, people and buses: busiest around 7pm (57/100), calmest around 2pm (29/100).
- JB → SG on weekdays, cars: busiest around 6am (60/100), calmest around 2pm (32/100).
- JB → SG on weekdays, people and buses: busiest around 7pm (53/100), calmest around 2pm (30/100).
In general: going into Singapore, avoid weekday mornings before 9am and weekday evenings from 6pm to 9pm. Going into JB, avoid weekday evenings from 6pm to 9pm. Weekdays from late morning to mid-afternoon are the calmest both ways.

How to read these charts
Each bar is the average of our live jam score in that hour, across all the days we have. We only count moments when people had actually posted about the queue, not our own guesses. Hours with reports on fewer than 5 days are shown striped, because a few posts are not enough to trust. Late at night we rarely get reports, so those hours are mostly striped.
An average hides the bad days. A normal Tuesday at 7pm and the evening before a long weekend look very different, and public holidays, school holidays, rain and accidents can all make a quiet hour jialat. Use the charts to plan, then check the live score before you leave.
These charts cover Woodlands only. We do not yet have enough reports from Tuas to draw a fair chart. We update them as more reports come in.
