I saw the Mediterranean Sea before I was one year old. As for an actual ocean, I am not sure, it was probably the Pacific when I was in Australia (at the age of 29).
I was born and have lived in Virginia my entire life. The first time I saw the Atlantic Ocean was probably around 1984 and during an elementary school trip, when I was nine going on ten years old.
I was born in an inland city but my family moved to a Pacific island not long after. Story is that I was slow to learn to walk because our housegirl carried me all the time, so it was probably before I was 1.
Weston Super Sludge? You'd be lucky to see the sea at all, when ever I've gone (which I try not too, I prefer Weymouth) the sea is always out. Saying that, the first time I saw the sea for the first time was on my first holiday in August 84 when I was about ten months old pretty much around the corner from WSM at Brean. First time I properly saw the actual Atlantic Ocean was a couple of years ago when on on West Coast of Ireland.
I was 4 when we moved to Pensacola. Saw the Atlantic proper when I was 8 on a vacation trip to the penninsula. Saw the Pacific at 18.
No doubt sometime in the summer of 1961. We lived in Dorchester when I was born, and it was normal to make the rounds of Savin Hill, Malibu, and Tenean beaches, so I'm sure my mother brought me around as soon as the weather was nice enough.
May I add another question: When did you first smell the Sea? What I mean is that whenever I return home from the deep of Germany I notice the milder air up here, surrounded by the sea! (and that I think it relates to the smell of the air).
Probably when my parents walked out of the hospital with me to take me home, so I'm going to say 4 days old.
I was born in May, so I probably smelled the ocean shortly after I was born, the first day it was warm enough to open the windows.
The sea has a smell? But perhaps that's because I've lived very close to the sea for a decades that I don't notice it.
When I lived close to the sea I never noticed the smell. We moved from there ten years ago, and a few years ago we attended our niece's wedding and stayed at a hotel right by the seaside. That was the first time I really noticed the smell of the sea.
Different seas smell stronger. The Atlantic on the US east coast is very pungent. You can barely smell the Pacific in CA or where I live in comparison. It's all about rotting stuff.
