Het weer in Mamaia (Constanța) in november

Romania's forum describes February as genuinely cold nationwide, typically 0-5C by day with a real chance of snow, and one Bucharest visitor reported nights as low as -14C during a cold snap. Mamaia's coastal position moderates things somewhat compared to inland cities, but posters were clear the Black Sea coast is fundamentally a summer destination - most of what makes Mamaia appealing (the beach, the resort strip) is dormant this time of year, so it's really a stopover rather than a winter destination in its own right.

Forum posters name the July 15 to August 25 window as the best time to visit Mamaia, when the Black Sea stays warm and comparatively shallow near shore. Posters describe typical conditions as very warm, above 30C in Romania's lower-elevation coastal areas, with one visitor even in late September reporting a fabulous 32C with clear skies and a gentle breeze - suggesting August itself should run at least as warm. Posters consistently flag real crowding as the trade-off for that peak-season heat and sunshine, describing Mamaia as one of Romania's more traditional resorts and especially packed during July and August. Posters generally rate August as ideal for a beach vacation here, crowds notwithstanding.
