Which radars cover Seabrook Beach?
The closest NEXRAD Doppler radar is KBOX (Boston, MA), about 66 miles south-southwest. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Seabrook Beach | View |
|---|---|---|---|
| KBOX Boston, MA | 66 mi south-southwest | 5,200 ft | Good — most storms and steady rain or snow show clearly |
| KGYX Portland, ME | 75 mi north-northeast | 6,300 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KCXX Burlington, VT | 162 mi northwest | 20,700 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
