You've probably heard the rumors that May is the "sweet spot" for a Bermuda getaway. Honestly? It's mostly true, but there is a specific rhythm to the island this time of year that catches first-timers off guard. May 2025 is shaping up to be a classic transition month. It's that weird, wonderful window where the island stops pretending it’s "cool" and starts leaning hard into the subtropical heat.
If you're looking for the Bermuda weather in May 2025, you aren't just looking for a spreadsheet of numbers. You want to know if you'll actually want to get in the water at Horseshoe Bay or if you'll be shivering the second a cloud blocks the sun.

The Temperature Reality Check
Let's talk air. Historically, and looking at the trends for 2025, you’re looking at daytime highs that hover around 76°F (24°C). By the end of the month, it frequently pushes 80°F (27°C).
Is it hot? Kinda.
Is it sweltering? Not yet.
The nights are the real hero here. They dip to about 67°F (19°C). It’s that perfect "balcony and a glass of wine" weather where you don't need the AC, but you aren't sweating through your sheets either. But here’s the thing: the humidity starts its upward climb in May. You’ll feel it. That crisp Atlantic air starts getting a bit "heavy" as the month progresses.
Can You Actually Swim?
This is the big debate among locals and visitors. Bermudians have a very strict rule: they do not get in the water until Bermuda Day, which falls on Friday, May 23, 2025. Before that? They think the water is freezing.
For the rest of us? The water temperature averages around 72°F (22°C).
If you’re coming from the UK or the US Northeast, that feels like a heated pool. If you’re coming from Florida, it’ll feel like an ice bath. It’s refreshing, sure, but you might want a "shorty" wetsuit if you plan on snorkeling for more than twenty minutes. The visibility, however, is world-class in May because the plankton hasn't gone into full summer bloom yet.
Rain, Clouds, and the "May Grey" Myth
Don't panic if you see rain on your 10-day forecast. Bermuda doesn't really have a "monsoon season." Rain in May usually comes in the form of short, violent bursts that last ten minutes and then vanish like they were never there.
- Average Rainfall: About 3.3 inches for the month.
- Sunshine: You get roughly 8 hours of bright sun a day.
- The Cloud Factor: Cloud cover actually increases throughout May, rising from 48% to 60%.
Basically, you’ll get those dramatic, puffy white clouds that look great in photos but might briefly block your tanning session.
Why the 2025 Forecast is a Little Different
Meteorologists at NOAA and the Bermuda Weather Service have been keeping a close eye on Atlantic sea surface temperatures. For 2025, the Atlantic is running a bit warmer than the 30-year average.
What does that mean for you?
It means the humidity might kick in earlier than usual. It also means the chance of a "pre-season" subtropical depression is slightly elevated, though still very low. Remember, hurricane season doesn't officially start until June 1st, so May is generally considered a "safe" month for travel.
Bermuda Day: The May 23rd Turning Point
If your trip overlaps with Friday, May 23, 2025, you aren't just getting weather; you're getting a cultural explosion. This is the 46th Annual Bermuda Day. The parade in Hamilton is loud, colorful, and intense.

The weather for Bermuda Day is traditionally "scorching," at least by local standards. It’s the day the island officially declares it is summer. Expect the humidity to be high and the sun to be biting. If you're standing on Front Street watching the Gombey dancers, you will need high-SPF sunscreen. The UV index in Bermuda during late May is no joke—it often hits 8 or 9 (Very High).
Packing for the Transition
Packing for May is a bit of a puzzle. You can't just bring bikinis and board shorts.
- The Layer Rule: You need a light sweater or a linen blazer for the evenings. The ocean breeze at night can feel surprisingly chilly when you're dining seaside.
- The "Smart-Casual" Factor: Bermuda isn't Cancun. If you walk into a restaurant in Hamilton in just a swimsuit cover-up, you're going to get some looks.
- Footwear: Bring sneakers for the Railway Trail. The limestone can be slippery if it catches one of those quick May showers.
What Nobody Tells You About May
The "Bermuda High" (a semi-permanent high-pressure system) starts to establish itself in May. This is what gives the island its steady breezes. If you're a sailor or into windsurfing, May is arguably the best month of the year. The winds are consistent—usually coming from the South or Southwest—but they aren't "stormy."
Also, the flora is peaking. The oleanders and hibiscus are in full tilt. The island smells like flowers and salt. Honestly, it’s a sensory overload that you just don't get in the dead of August when the heat kills off some of the more delicate blooms.
Actionable Advice for Your May 2025 Trip
- Book Your Ferry Early: The seasonal orange route from Dockyard to St. George's is fully operational in May. It's the best $5 view you'll ever get.
- Watch the Wind: If the wind is coming from the South, head to the North Shore beaches (like Shelly Bay) for calm water. If it’s coming from the North, the South Shore (Horseshoe, Warwick Long Bay) will be wavy but stunning.
- Sunscreen Strategy: Apply more than you think. The breeze masks the heat, so you won't feel yourself burning until it's too late.
- Bermuda Day Logistics: If you are in Hamilton on May 23rd, the city basically shuts down for the parade. Don't plan on catching a taxi easily that afternoon.
May in Bermuda is about the balance between the cool remnants of spring and the impending sizzle of summer. It's a month of "firsts"—the first swim, the first boat party, and the first time you'll need to wipe sweat off your forehead. Plan for the sun, pack for the breeze, and you'll see exactly why this is the month locals love most.
Your next step for a May 2025 trip should be checking the specific cruise or flight schedules for the Bermuda Day weekend, as Hamilton hotel capacity usually hits 100% at least six months in advance.
