Northern Lights in Massachusetts: Tonight's Aurora Forecast
Massachusetts needs about Kp 7 on the northern horizon. Live NOAA Kp, tonight's cloud cover and moon, the aurora oval map, and the darkest places to watch from.
Aurora season is open — equinox weeks bring the most stormsThe Massachusetts aurora season at a glance
Live · NOAA SWPCThe 10–11 May 2024 G5 storm was visible from Boston Common and Cape Cod beaches. NOAA rated it G5, the top of its scale — nothing weaker reaches Massachusetts without a camera.
Can you see the northern lights tonight in Massachusetts?
The verdict below combines NOAA SWPC's planetary Kp forecast with the Kp 7 that Massachusetts's darkest northern spots need, tonight's cloud cover from Open-Meteo at Mount Greylock summit, the moon, and the hours of full darkness. Then each city and dark-sky site gets its own cloud reading — the sky often clears inland when the lakeshore or coast is socked in.

The aurora oval over Massachusetts right now
NOAA's OVATION model maps where aurora is likely overhead in the next 30–90 minutes. Green cells mean a small chance, red a strong one. The map opens on Mount Greylock summit; enter a ZIP to recenter, and widen the span to see the whole oval across Canada.

Best places to see the northern lights in Massachusetts
You need a real storm (Kp 7+). When one is forecast, get to the Quabbin or the Berkshires early — the North Shore beaches fill up fast. Use your phone camera in night mode to confirm a faint red glow your eyes can't pick out.
Mount Greylock summit
Highest point in the state; looks north over the Hoosac Valley toward Vermont.
Parker River National Wildlife Refuge, Plum Island
A barrier beach facing open ocean to the north-east, away from Boston's glow.
Race Point Beach, Provincetown
The tip of Cape Cod has water on three sides — the best ocean horizon in the state.
Quabbin Reservoir, Enfield Lookout
Forty square miles of protected watershed with no lights on the water.
When to see the northern lights in Massachusetts
September – November autumn season
The equinox weeks around September 22 are statistically the most geomagnetically active of the year, and nights are long again. For Massachusetts this is the best window to catch a G3+ storm, which happen most often around the equinoxes.
December – February cold and clear
Geomagnetic activity dips, but long nights and cold dry air give the best transparency of the year. Watch the 3-day forecast; any G3+ storm is worth a drive north.
March – April spring season
The March equinox brings the second annual peak in geomagnetic storms. Nights are still long in March. By late April the late sunsets start to cut into viewing time.
May – August short nights
Short nights and twilight — summer haze and late sunsets make faint displays hard to see. Big storms still punch through: NOAA rated the 10–11 May 2024 event G5, the top of its scale, and it was seen across most of the lower 48.
How to see — and photograph — the aurora from Massachusetts
Kp, geomagnetic latitude, and solar cycle 25
The aurora forms in an oval around the geomagnetic pole, which sits over northern Canada rather than at the geographic pole. That tilt is why the eastern United States is magnetically "further north" than the West: Massachusetts is at about 52° geomagnetic latitude. The planetary K-index (Kp, 0–9) measures how disturbed Earth's magnetic field is; as Kp rises, the oval expands toward the equator by roughly 2° of latitude per step. From Massachusetts's darkest northern areas, Kp 7 brings the oval's edge into view on the horizon; Kp 9 puts it overhead.
NOAA's G-scale is a simpler label on the same thing: G1 (Kp 5) minor, G2 (Kp 6) moderate, G3 (Kp 7) strong, G4 (Kp 8) severe, G5 (Kp 9) extreme. Solar cycle 25 reached its maximum in 2024–2025 — NOAA rated the 10–11 May 2024 storm G5, the top of its scale — and the declining phase of a cycle historically produces the biggest individual storms, so 2026 and 2027 remain good years to watch. Storms also cluster near the equinoxes, which is why September–October and March–April are "aurora season" everywhere in the lower 48.
