Every forecast across Greater Portland, highway-clear.
Official National Weather Service forecasts for Greater Portland — Cumberland, York and Sagadahoc counties, from Casco Bay and the Old Port south along the beaches to Biddeford, Kennebunk and Kittery, and inland to Sanford, Standish and Bridgton.
Every Maine region shares one system — the same maps, the same live radar, the same climate record. Portland is where the nor'easters come ashore. The rain-snow line sets up along this coast almost every winter storm, sometimes right over the peninsula, and a foot inland at Gorham can mean rain at the waterfront. In summer the sea breeze holds the beaches twenty degrees cooler than Sanford.
