The state’s housing market ended 2015 on a strong note, especially in some spots.

Sales of single-family homes in Massachusetts surged 16.6 percent in December, while the median price climbed to $335,000, up 4.7 percent compared to a year prior, according to figures out Wednesday from the Warren Group. For the full year, sales jumped 10.5 percent while the median price ticked up 3 percent to $340,000. Condos notched similar gains.

Statewide, home prices are now at their highest level since 2007, though still a bit below the $355,000 median price in 2005. At $316,810, median condo prices have never been higher.

The figures came after a slow start to the year, which market-watchers attributed to the rough weather last winter. Once spring hit, sales picked up, and remained so, said Warren Group chief executive Tim Warren.

“The market stayed strong all the way through December because the region’s economy is very strong,’’ he said. “Buyers felt confident in their futures, and sellers finally saw the value of their homes return to near-peak levels in many parts of the state.’’

But not everywhere had the same results. Among cities, towns, and neighborhoods in Eastern Massachusetts with at least 50 home sales, Charlestown saw prices climb 33 percent in 2015, while Medfield, Jamaica Plain, and Winthrop all had price gains of at least 15 percent. Meanwhile prices in Middleton fell 15 percent compared to last year.

Among the 263 communities in Massachusetts with at least 500 single-family home sales over the last decade, 57 now have median prices above 2005 levels, central Boston and Cambridge each up more than 80 percent since then. The vast majority of towns, though, remain below their prior highs. In Eastern Massachusetts, Hyannis, Somerset, and New Bedford remain deepest underwater, with home prices in each community at least 22 percent below 2005.
