Historical statistics for July 2025, not live status or a forecast for this year’s July. For today’s conditions at EWR, see live FAA status.
EWR in July carries a cancellation problem, not just a delay problem: 6.8% of scheduled flights never operate, against 2.5% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 10,478 flights, of which Republic Airways flew 1,981 at 72.2% on time.
Republic Airways is the most reliable of the six carriers covered here at 72.2% on time across 1,981 flights.

These figures cover 10,478 departures from Newark Liberty International in July 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
July next to EWR's other months
Against EWR's own year, July ran 10 points worse than the twelve-month rate of 77.7%, which makes it the worst of the twelve months in the data. Cancellations are where July stands out: 6.82% of scheduled departures were called off, 2.3 times the airport's rate across the year.

Departure window
The best time of day to leave EWR in July
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 44 points, against 10 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am1,780 flights89.6%
- 8am–11am1,853 flights85.5%
- 11am–2pm1,643 flights76.4%
- 2pm–5pm2,004 flights58.5%
- 5pm–8pm1,794 flights45.1%
- 8pm–5am1,404 flights45.7%
Scale runs 35% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 45.1% on time, against 89.6% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 2pm–5pm window is the busiest, with 2,004 flights scheduled in it.
Across the week, Saturday is the strongest day at 73.5% on time and Monday the weakest at 64.1%. 9 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at EWR in July
The choice of carrier is not cosmetic here. Republic Airways arrives on time 72.2% of the time; JetBlue Airways manages 62.5%. Sample sizes sit next to every figure, because a two-point gap across 513 flights means less than a ten-point one.

| United Airlines | 5,582 | 67.7% | 107 min | 4.64% | C− |

Republic Airways cancels 13.4% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
What held EWR up in July
One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 327,000 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.
- 43%Late-arriving aircraft
- 24%National Airspace System
- 22%Carrier
- 10%Extreme weather
- 0%Security
43% 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 327,000 reported delay minutes here, that single category outweighs weather by 4 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 327,252 reported delay minutes.
Cancellations run at 6.82%, against 2.45% nationally. That is about one flight in fifteen cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 17.7% of arrivals land a full hour or more behind schedule, against 12.1% 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.
What to do with this
Flying from EWR in July
For a July trip through EWR: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 89.6% on time, and with 17.7% of arrivals an hour or more late, a connection here deserves more slack than the same trip in May would.
