Northern lights in Ohio tonight
The aurora forecast for Ohio, hour by hour: the Kp index NOAA expects, how dark it gets, the Moon and the clouds, for the north of the state (Toledo) where the odds are best.
Unlikely Sunday, October 25
The highest Kp expected after dark tonight is 3. Toledo (north Ohio) needs about Kp 7 to see the aurora low on the northern horizon, and the sky cover forecast after dark averages 30%. The Moon is 100% lit.

What Kp you need in Ohio
The farther north (in magnetic terms) you stand, the lower the Kp you need. From Toledo, an aurora usually shows low on the northern horizon once Kp reaches about 7; overhead displays need about two steps more. A phone camera in night mode often records it one step earlier than the eye. How we estimate this: our method.
How often the aurora reaches Ohio
Our own count from the official Kp archive: on how many nights each year the Kp index reached about 7 or more while it was dark at Toledo. Clouds are not counted, so the real number of nights with a visible aurora is lower. Over the last 10 years the average was 2.4 nights a year; in 2025 it was 8.

The next 27 days
NOAA's 27-day outlook has no day with a largest Kp near the 7 that Toledo needs. The outlook repeats the Sun's 27-day rotation and cannot see sudden storms, so check the 3-day forecast too.

Where to watch in Ohio
Ohio's best aurora spots are along Lake Erie, where the shoreline faces north over the water. Toledo and the islands region see displays during strong storms. Columbus and Cincinnati need bigger events and a drive away from the lights.
Stand on a Lake Erie beach and look out over the lake. Inland, pick open farmland north of town.
- Maumee Bay State Park: Lake Erie state park just east of Toledo
- East Harbor State Park: Lake Erie state park on the Marblehead Peninsula
- Headlands Beach State Park: long Lake Erie beach in Mentor, northeast of Cleveland
- Observatory Park: county park built for stargazing in Geauga County, east of Cleveland

Questions people ask
Can you see the northern lights in Ohio?
Yes, on active nights. From Toledo it takes about Kp 7, which happened on about 2.4 nights a year over the last 10 years (before clouds).
What time is best?
Usually between 10 pm and 2 am local time, when the sky is fully dark and your location faces the night side of the auroral oval. Storms can bring it earlier or later.
Which way should I look?
North, toward a low, open horizon away from city lights. In strong storms the aurora can climb higher or appear overhead.
Is this an official forecast?
No. It is our estimate built from NOAA's Kp forecast, the National Weather Service sky cover forecast and the Sun and Moon positions. It is not a promise.
