外洋クルーズ寄港地 海況・テンダーリスク＆混雑トラッカー

返金不可の寄港地観光を予約する前に——サントリーニ島のケーブルカー90分待ちや、強風によるテンダーボート（通船）の上陸中止、ラヴェンナからヴェネツィアへの2時間バス移動に驚く前に——主要12港の今後7日間の沖合波浪予報と通年の港湾事情を確認しましょう。

地中海：入場制限＆長距離移動スポット

Greece·8,000 pax/day cap · €20 fee

Santorini (Thira)

抜港・猛暑の高リスク
沖合の波高: 2.1 m最大瞬間風速: 27 kt最高気温: 20°C

着岸・テンダーボートの実情: 100% open-caldera tender to Old Port (Skala) for independent guests; ship-sold excursions tender to Athinios ferry port first.

市内移動と実際の費用: Cable car from Old Port to Fira (€10 each way, 6 seats/car, 1,200 pax/hr max) or 588 slippery stone steps shared with donkeys.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Strict 8,000/day municipal cruise cap + €20 peak-season disembarkation levy (Jun–Sep). When 3+ ships overlap Tue–Thu, cable car queues hit 60–90 min each way.

シニア移動判定: High friction for walkers/scooters: tender step-across in swell + long standing queue in direct sun at the cable car.

プロの対策: Book an early morning ship excursion that tenders to Athinios (where motorcoaches meet you at sea level) or take the local water-taxi transfer directly from Old Port to Ammoudi Bay (Oia).

Greece·€20 peak island fee · Wind-prone

Mykonos

抜港・猛暑の高リスク
沖合の波高: 1.3 m最大瞬間風速: 29 kt最高気温: 19°C

着岸・テンダーボートの実情: One mega-ship docks at Tourlos New Port pier; additional ships anchor offshore and tender directly to Old Harbor.

市内移動と実際の費用: From Tourlos Pier: €2.50 SeaBus water taxi (10 min to Old Harbor) or €10–€12 cruise shuttle bus. Do not walk the narrow shoulderless coastal road.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Greece's €20 peak-season island levy applies Jun–Sep. Famous 'Meltemi' katabatic north winds funnel down the Mykonos strait in July–August, causing ~1 in 5 summer tender calls to delay or skip.

シニア移動判定: Moderate: once in Chora (Mykonos Town), streets are flat marble flagstones, though narrow and crowded around Little Venice.

プロの対策: Always take the €2.50 SeaBus from the Tourlos pier instead of the €12 cruise line shuttle bus—it drops you right at the Old Harbor cafés with zero stairs.

Strong wind gusts (29 kt / 33 mph)Mykonos
Italy·>25,000 GT Lagoon Ban · €5–€10 Day Fee

Venice (Ravenna / Marghera)

通常運航
沖合の波高: 1.1 m最大瞬間風速: 20 kt最高気温: 14°C

着岸・テンダーボートの実情: All ships >25,000 GT are banned from the Giudecca Canal. Royal Caribbean, Celebrity & Princess dock in Ravenna (90 mi / 145 km south); MSC, NCL & Holland America use industrial Marghera or Trieste.

市内移動と実際の費用: From Ravenna (Porto Corsini): 2 hr 15 min–2 hr 45 min motorcoach transfer ($65–$95 pp one-way). From Marghera/Fusina: 25–40 min coach/boat transfer after mandatory check-in at Marittima.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Venice enforces a €5–€10 Day-Tripper Access Fee (Contributo di Accesso) with QR checks at Piazzale Roma & Santa Lucia station on peak spring/summer dates.

シニア移動判定: High fatigue on turnaround days: 2.5-hour coach ride from Ravenna + Venice's 400+ stepped footbridges and vaporetto boarding ramps.

プロの対策: Check your booking confirmation's fine print before booking flights: if your ship actually sails from Ravenna, flying into Bologna (BLQ, 75 min away) is often far easier than Venice Marco Polo (VCE).

Favorable 7-day marine window (3.6 ft / 1.1 m swell · 20 kt wind)Venice
Italy·45 mi / 72 km from Rome · Heat Alert

Rome (Civitavecchia)

通常運航
沖合の波高: 0.7 m最大瞬間風速: 11 kt最高気温: 19°C

着岸・テンダーボートの実情: Deep-water pier at Civitavecchia (zero tender risk), but walking inside the industrial port is banned—mandatory free port shuttle to Largo della Pace gate.

市内移動と実際の費用: 75–90 min each way to Rome: Trenitalia regional train (€12 round-trip with BIRG pass; drop at Roma S. Pietro for Vatican) or Civitavecchia Express (€16) or private van (€350–€450/day).

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Up to 6 mega-ships (20,000+ cruisers) disembark simultaneously between 7:00–8:30 AM. July–August pavement temps in the Roman Forum regularly exceed 98°F / 37°C with zero shade.

シニア移動判定: Strenuous: 3 hours of round-trip transit + 5–7 miles of uneven Roman cobblestones (sampietrini) and train station stairs.

プロの対策: If visiting the Vatican or Piazza Navona, get off the train at Roma San Pietro station (50 min from Civitavecchia) instead of riding an extra 25 min into chaotic Roma Termini.

カリブ海＆バハマ：うねり＆巨大桟橋の混雑

Bahamas·2-Mega-Ship Pier · 25 kt Wind Limit

CocoCay & Nassau

通常運航
沖合の波高: 1.0 m最大瞬間風速: 20 kt最高気温: 28°C

着岸・テンダーボートの実情: Both CocoCay and Nassau have deep-water piers (no tenders), but CocoCay's exposed north pier cannot safely berth Icon/Oasis-class hulls when cold-front north swells or crosswinds exceed ~25–28 knots.

市内移動と実際の費用: CocoCay: Free island tram loop from the pier + complimentary beach wheelchairs. Nassau: Reformed Prince George Wharf is a 5–8 min flat walk to Bay Street ($5 water taxi to Paradise Island).

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: CocoCay caps at 2 Royal Caribbean/Celebrity ships/day (~11,000–13,000 guests). Nassau can host up to 6 ships simultaneously (25,000+ pax).

シニア移動判定: Excellent once docked: CocoCay's paved pathways, pier trams, and sand wheelchairs are the gold standard for accessibility.

プロの対策: In winter (Dec–Mar), Passing US cold fronts trigger 15–20% of CocoCay pier aborts—don't prepay $200+ waterpark passes without checking that missed-port refunds go back to your card, not expiring onboard credit.

Cayman Islands·100% Tender Port · No Cruise Pier

Grand Cayman (George Town)

注意 / 波やや高し
沖合の波高: 1.0 m最大瞬間風速: 22 kt最高気温: 28°C

着岸・テンダーボートの実情: No cruise pier exists in Grand Cayman (voters blocked it to protect coral reefs). All ships anchor off George Town and use double-deck local tenders.

市内移動と実際の費用: Tenders land right in downtown George Town at Royal Watler / North or South Terminal. Shared vans to Seven Mile Beach cost $6–$8 pp right outside the gate.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: When winter 'Nor'wester' swells hit George Town Harbor, max 2–3 ships can relocate to sheltered Spotts Bay on the south coast (20 min taxi from town); excess ships must skip the island entirely.

シニア移動判定: Moderate-to-High: boarding rolling tenders in swell requires stepping across a moving ramp; collapsible wheelchairs only.

プロの対策: If your ship diverts to Spotts Bay dock due to swell, expect heavy congestion for taxis—pre-booked Stingray City operators automatically reroute their buses to pick you up at Spotts.

Mexico·Up to 8 Ships / 28,000 Pax Daily

Cozumel

通常運航
沖合の波高: 0.3 m最大瞬間風速: 14 kt最高気温: 30°C

着岸・テンダーボートの実情: 3 deep-water piers (Punta Langosta downtown; International & Puerta Maya 3 miles south). Almost never skips, but the exposed concrete pier walk is 1,200+ ft in blazing sun.

市内移動と実際の費用: Regulated taxi stands at every pier ($15–$18 per cab for up to 4 guests to beach clubs). Beware the 45-min high-speed ferry to Playa del Carmen (for Tulum/Chichen Itza): the Cozumel Channel is notorious for rough cross-swell seasickness.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Busiest cruise port in the Western Hemisphere: Tue–Thu regularly see 6 to 8 mega-ships (22,000–28,000 passengers) competing for beach club loungers and taxis.

シニア移動判定: Watch the 1/4-mile unshaded pier walk: request a complimentary cycle-rickshaw (pedicab, tip $3–$5) from the ship gangway to the terminal entrance.

プロの対策: On 6+ ship days, skip the crowded free beaches and book a capacity-capped beach club (Nachi Cocom caps at 130 guests/day) or stay on the island rather than enduring the rough mainland ferry to Tulum.

Favorable 7-day marine window (1 ft / 0.3 m swell · 14 kt wind)Cozumel
Mexico·100% Tender · Pacific Surge

Cabo San Lucas

注意 / 波やや高し
沖合の波高: 1.4 m最大瞬間風速: 22 kt最高気温: 30°C

着岸・テンダーボートの実情: 100% open-bay tender where the Pacific Ocean meets the Sea of Cortez. Long-period Pacific groundswells roll around Land's End, making tender boarding bouncy.

市内移動と実際の費用: Tenders dock directly at the Cabo Marina pier. Water taxis to Lover's Beach / The Arch cost $12–$15 pp right at the marina.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Many Mexican Riviera itineraries only schedule a short 6.5-hour call (e.g., 11:00 AM–5:30 PM), meaning losing 90 minutes waiting for tender ticket group #18 cuts your port day in half.

シニア移動判定: Moderate: Marina boardwalk is flat and paved, but Pacific swell causes noticeable vertical rise/fall at the ship's tender platform.

プロの対策: Line up 25 minutes before tender ticket distribution starts in the morning—getting off on Tender #1–3 gives you nearly two extra hours ashore on short Cabo calls.

Moderate chop (4.6 ft / 1.4 m)Cabo San Lucas

アラスカ＆北米：郊外岸壁＆氷河入場枠

Alaska, USA·5-Ship / 16k Daily Cap · Glacier Permit Cap

Juneau

注意 / 波やや高し
沖合の波高: 0.5 m最大瞬間風速: 26 kt最高気温: 6°C

着岸・テンダーボートの実情: 4 downtown berths (CT, AS, FK,ACT), but the 4th & 5th ships use AJ Dock (1.2 mi south, mandatory shuttle) or anchor in Gastineau Channel and tender.

市内移動と実際の費用: Downtown berths step right off at the Mt. Roberts Tramway. However, U.S. Forest Service commercial visitor caps at Mendenhall Glacier mean walk-up 'Blue Bus' glacier shuttles frequently sell out by 10:30 AM.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Juneau enforces a 5-large-ship daily limit plus a 2026 passenger cap (16,000 pax/day Sun–Fri, 12,000 on Saturdays). Helicopter glacier landings cancel ~25–30% of the time due to low cloud ceilings.

シニア移動判定: Good at downtown berths (CT/AS), but AJ Dock requires boarding school-bus shuttles with steep steps.

プロの対策: Never wait until you dock in Juneau to book Mendenhall Glacier transport—commercial Forest Service permits cap daily bus seats, and standard taxis cost $90+ round-trip and cannot enter the bus drop zone.

Breezy channel gusts (26 kt / 30 mph)Juneau
Alaska, USA·Ward Cove = 7 mi Out of Town

Ketchikan (Downtown vs. Ward Cove)

抜港・猛暑の高リスク
沖合の波高: 1.4 m最大瞬間風速: 39 kt最高気温: 9°C

着岸・テンダーボートの実情: Princess, Holland America, Celebrity & Royal Caribbean dock right downtown at Berths 1–4 (steps from Creek Street). Norwegian (NCL), Oceania & Regent dock at private Ward Cove, 7 miles north.

市内移動と実際の費用: From Ward Cove: Free shuttle bus takes 20–25 min each way along a two-lane road, dropping at Berth 4 (still a 10–15 min walk to Creek Street). Round-trip shuttle queues + transit eat 60–90 minutes of a short 5–6 hour port call.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Peak summer days bring 4 downtown ships + 2 Ward Cove mega-ships (~18,000 guests into a town of 8,000 residents).

シニア移動判定: Crucial line distinction: Holland America & Princess put you 100 yards from downtown; NCL's Ward Cove requires long warehouse walks and shuttle lines.

プロの対策: If sailing NCL to Ward Cove on a short 7:00 AM–1:30 PM call, book an excursion that departs directly from the Ward Cove dock rather than burning 90 minutes riding the town shuttle back and forth.

Strong wind gusts (39 kt / 45 mph)Ketchikan
Alaska, USA·Rockslide Mitigation · Wind Tunnel

Skagway

通常運航
沖合の波高: 0.5 m最大瞬間風速: 19 kt最高気温: 7°C

着岸・テンダーボートの実情: Broadway & Ore Docks have direct walk-off access; Railroad Dock (used by large Royal Caribbean & Princess ships) operates under rockslide mitigation rules that require shuttle buses or short tender runs from the forward berth.

市内移動と実際の費用: Flat 8-minute walk (or $2 SMART town shuttle) into historic Broadway Street. White Pass & Yukon Route train boards directly adjacent to the docks.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Lynn Canal acts as a natural fjord wind tunnel: afternoon southerly winds frequently hit 25–35 knots, complicating tender operations at Railroad Dock Forward.

シニア移動判定: Very flat town grid once past the dock, and the White Pass Scenic Railway has hydraulic wheelchair lifts on every departure.

プロの対策: Book the morning departure of the White Pass & Yukon Route Railway—morning clouds often burn off by 10 AM and afternoon fjord winds won't affect your return to the ship.

Smooth marine conditions today (1.6 ft swell · 19 kt wind), with 6 choppy/breezy day(s) in the 7-day outlook.Skagway
Maine, USA·1,000 Pax/Day Cap · 100% Tender

Bar Harbor (Acadia)

注意 / 波やや高し
沖合の波高: 0.5 m最大瞬間風速: 22 kt最高気温: 20°C

着岸・テンダーボートの実情: 100% tender port anchoring in Frenchman Bay. At low tide (11-foot tidal range), the Town Pier gangway ramp becomes noticeably steep.

市内移動と実際の費用: Tenders land right at the Village Green / Main Street. Free propane-powered Island Explorer buses run to Acadia National Park from late June through mid-October.

乗客数制限と混雑ピーク & プロの対策

乗客数制限と混雑ピーク: Strict municipal 1,000-passenger daily disembarkation cap upheld by federal court—nearly all large mainstream ships have been forced to drop Bar Harbor for Portland or Eastport unless grandfathered or under 1,000 berths.

シニア移動判定: Check low-tide timing: the floating tender dock ramp at Bar Harbor Town Pier can hit a steep incline during extreme low tides.

プロの対策: If visiting Cadillac Mountain in Acadia independently, remember the National Park Service requires timed vehicle summit reservations ($6) released 2 days ahead at 10:00 AM ET.
