A humid, four-season Central Jersey climate

Somerville experiences hot, humid summers and cold winters typical of inland Central New Jersey, distinct from the more coastal-moderated climate at the Jersey Shore.

No direct coastal-storm or hurricane-landfall risk

Somerville sits well inland from the Jersey Shore and carries no direct hurricane-landfall or coastal storm-surge risk -- see new-jersey.js for the state's fuller, two-layered coastal-versus-inland flood-risk disclosure.

A real, regional Raritan River flood-monitoring concern

Somerset County officials actively monitor the Raritan River for flood risk during storm events, a real, ongoing regional concern. This pass did not identify a Somerville-specific FEMA flood-zone breakdown distinct from this county-level monitoring -- confirm current, address-specific flood-zone status directly for any target property, particularly near the river itself.
