In the Northern Hemisphere, the synoptic winds should oppose the seabreeze if synoptic low pressure is off to the left \ synoptic high pressure is off to the right when looking at the ocean along a regionally representative shoreline during the daytime...
And the synoptic winds will oppose the landbreeze if synoptic low pressure is off to the right \ synoptic high pressure is off to the left when looking at the ocean along a representative shoreline during the night\early morning.
(Flip directions for SH) Also it's worth noting that seabreeze boundary "fronts" can penetrate quite far inland and take time to fade away... even after temperatures have equalized at the shoreline or the landbreeze has started to develop near the coast... and if there are thunderstorms along the seabreeze boundaries, the cool air released by the rainfall often further reinforces the thermal gradient... I've certainly seen seabreeze boundaries persist deep into the night hundreds of miles from the coast.
