The average highs hover around a glorious 72°F (22°C). That’s short-sleeves-in-the-sun and a light jacket for evening strolls weather. The sun still shines bright, but with a softer, golden glow that makes the historic mansions look like they’re posing for a postcard. And the humidity? It drops like a rock after Labor Day, so your hair will actually behave.
This isn’t just “nice” weather—it’s adventure weather. The ocean water is still warm from the summer sun, often in the high 60s through mid-September. That means you can actually swim, paddleboard, or kayak without turning into a human popsicle. Go ahead, dip your toes in—I dare you.
Your New Favorite Outdoor Escape
Think of the Cliff Walk in September. The crowds have thinned, the wild roses are still blooming, and the breeze carries salt and a hint of autumn. You can hike the entire 3.5-mile stretch without bumping elbows, stopping to watch the waves crash against the rocks. This is the Newport that locals cherish, and now it’s yours to discover.
Or maybe you’re a sailor at heart. September’s winds are steady and sweet, perfect for a sunset sail. Book a small boat charter, or just grab a seat at a waterfront bar on Bowen’s Wharf. Watch the sky turn mango and lavender as the temperature dips to a cozy 60°F. Don’t forget a sweater—you’ll thank me later.
