Living near a warm-ish ocean has a moderating effect on temperatures. The last place I lived was about a mile, or just under 2 km, from the ocean, and we didn't even need heating in winter. I think the coldest it ever got there was 6 C, early morning in the middle of winter one time. Normal winter minimums were around 10 Celsius. Didn't need a jacket even. And unpleasantly hot weather was rare as well.
A lot of the smell of the sea comes from things like stagnant saltwater on rock platforms, seaweed, mud flats, pollution. If the ocean is clean and there are sandy beaches without too much tidal variation in water levels, then there isn't much smell at all.
