While Staten Island, in general, can be relatively humid because of its proximity to the bay, the spring and summer months are generally pleasant, if not a little sticky. As an upper middle class neighborhood, the area is nice to explore and will generally help you avoid the more tourist-heavy attractions in New York City.
If you’re venturing up towards Fort Wadsworth, Arrochar has a few more hills than most other places in New York. Staten Island, in general, is less urban-flatness and harbors more of a suburban feel. From Quintard Street up towards Sand Lane, you’ll likely find mostly flat terrain and going North of Sand Lane towards Lily Pond, you’ll run into those few humps here and there. None of it poses any real challenge to those walking about in the area unless they need regular assistance on any terrain. Arrochar can be much lighter in traffic as well when you venture closer to the housing areas, offering less risk than some of the busier parts of the city during rush hour. However, it might be wise to expect some foot traffic heading towards the Franklin D. Roosevelt Boardwalk during the late spring and summer months as the beach is not very far away.
While Arrochar has a few small green areas, most of them are playgrounds or recreational areas such as The Big Field or Old Town Playground. Wandering just outside of the Arrochar borders to the south will bring you to the much bigger and dog-friendly area known as Ocean Breeze Park. With more than 110 acres of recreational areas, horseback riding trails, and places to run and fish, Ocean Breeze offers plenty for any outdoor enthusiast. However, if you’re looking for places inside of Arrochar, you’re not exactly spoiled for choice, though the residential areas likely provide some small reprieve from the urban layout of most of New York City. The Big Field in particular, while not offering many utilities and lacking any fencing, can be a decent place to go for a little bit of open exercise with an energetic pooch. Otherwise, you’ll likely have to go the extra mile to find more natural areas to explore.
