Historical statistics for August 2025, not live status or a forecast for this year’s August. For today’s conditions at EWR, see live FAA status.
EWR in August lands a B, level with the national rate of 77.4%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 10,410 flights, of which Republic Airways flew 1,980 at 81.2% on time.
Republic Airways is the most reliable of the six carriers covered here at 81.2% on time across 1,980 flights.

EWR across all twelve months
These figures cover 10,410 departures from Newark Liberty International in August 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.
Against the year
August next to EWR's other months
Against EWR's own year, August ran level with the twelve-month rate of 77.7%, which makes it number seven of twelve months, best first. Cancellations were unusually low for EWR in August, at 1.20% against 3.03% across the year. Either side of it, July ran 68.2% on time and September 82.7%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window
The best time of day to leave EWR in August
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 points, against 9 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,798 flights91.7%
- 8am–11am1,790 flights88.5%
- 11am–2pm1,660 flights82.1%
- 2pm–5pm1,997 flights70.3%
- 5pm–8pm1,753 flights66.7%
- 8pm–5am1,412 flights66.5%
Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.7% of the time, against 66.5% for the overnight window. That is 25 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 1,997 flights scheduled in it.
Across the week, Tuesday is the strongest day at 87.6% on time and Thursday the weakest at 70.0%. 18 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at EWR in August
The choice of carrier is not cosmetic here. Republic Airways arrives on time 81.2% of the time; JetBlue Airways manages 72.5%. Sample sizes sit next to every figure, because a two-point gap across 514 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlines | 5,516 | 77.3% | 84 min | 0.94% | B+ |
| Republic Airways | 1,980 | 81.2% | 75 min | 2.02% | B |

Republic leads JetBlue by 9 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes
What held EWR up in August
One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 192,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 48%Late-arriving aircraft
- 27%Carrier
- 18%National Airspace System
- 7%Extreme weather
- 0%Security
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 192,000 reported delay minutes here, that single category outweighs weather by 7 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 192,020 reported delay minutes.
Cancellations sit at 1.20% against a national 1.08%, which is ordinary. Diversions add another 0.44%.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.0% of arrivals land a full hour or more behind schedule, against 8.2% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

Flying from EWR in August
