Best time to visit, month by month
Best time to visit Margaritaville Resort Cape Cod depends on what you want: for warm beach weather and full water-park hours, visit June–August; for fewer crowds, warm days, and clearer skies, aim for September or late May–June. Winter (December–March) is the quietest time for lower crowds and indoor amenities like the Fins Up! Indoor Water Park and St. Somewhere Spa, but ocean swimming will be cold.

What to expect by season
Summer (June–August) is the resort's busiest period: warmest air and ocean temperatures, outdoor-pool and Salty Rim Bar & Grill open weather permitting, and full water-park schedules during school vacation weeks.
Shoulder seasons—late May–June and September—offer mild, often pleasant weather, smaller crowds, and clearer skies in September, while many local ferry and sightseeing options remain operating.
- Summer: warmest days, busiest, beaches and outdoor amenities active
- Shoulder (May/June & September): fewer crowds, good weather for sightseeing and whale watching
- Fall (October–November): cooler, quieter; good for walks, golf, and off-peak rates
- Winter (Dec–Mar): lowest occupancy; indoor facilities (spa, indoor pool, water park with passes) remain available
Month-by-month at a glance
Below is a short month-by-month guide to typical conditions and what’s open. Exact hours and seasonal openings can vary year to year; check with the resort for current schedules.
Fins Up! Water Park has its own schedule and requires a separate admission pass (resort guests get a 50% discount code); outdoor pool and Salty Rim Bar & Grill operate subject to weather.
| Month | Typical conditions / resort notes |
|---|---|
| January–February | Cold, quiet; indoor facilities (spa, indoor pool) available; lowest visitor numbers |
| March–April | Cool spring transition; some outdoor services still limited; Fins Up! may have reduced hours |
| May | Late-May warms up; shoulder-season rates and fewer crowds; some outdoor amenities open |
| June | Warmer weather, outdoor pool usually open; start of high season for beaches and ferries |
| July–August | Peak summer—warmest air and ocean temps, busiest hotel and full summer hours |
| September | Often the best balance: warm days, clearer skies, smaller crowds; many activities still running |
| October–November | Cooler, quieter; good for off-season walks, golf and exploring nearby towns |
| December | Quiet, indoor amenities still available; limited beach activity due to cold |
When families should visit
Families who prioritize the indoor water park should book June–August or school vacation weeks when Fins Up! has its busiest schedule; remember every visitor, including non-swimmers and spectators, needs a pass.
If you want to mix water-park time with quiet afternoons, consider September or late May–June when the water park is open but crowds are smaller and local attractions remain accessible.
- Fins Up! Indoor Water Park: 30,000 sq ft; separate pass required for each person
- Resort guests receive a 50% discount code for water-park passes
- Children’s pool, lazy river, and waterslide available on-site
Beach and outdoor activity timing
Warmest ocean temperatures are in August (water averages around the mid-60s °F), so swimmers will find August the most comfortable month for Nantucket Sound beaches like Kalmus Beach and Craigville Beach.
Whale-watching season generally runs April–October, with June–September often the best months for sightings; ferry service to Nantucket and Martha’s Vineyard runs seasonally with frequent summer departures from Hyannis Harbor.
- Kalmus Beach: roughly 3 miles from the resort (good for windsurfing/kiteboarding and swimming in summer)
- Craigville Beach: about 4 miles away, a popular summer beach
- Whale watching: active April–October; peak viewing June–September
If you prefer quieter stays (late fall–spring)
Visit in late fall or winter for fewer guests, easier restaurant and attraction reservations, and lower onsite crowding. Note that ocean swimming will be cold outside summer months.
Indoor amenities like St. Somewhere Spa, Fins Up! (hours and pass requirements vary), and the fitness center remain options for off-season visits, but check spa hours—St. Somewhere Spa is closed Tuesdays and Wednesdays and has limited weekday hours.
- St. Somewhere Spa hours: Sunday–Monday 9 AM–3 PM; Friday–Saturday 9 AM–5 PM; Tuesday–Wednesday closed; Thursday by appointment
- Check Fins Up! Water Park hours before travel—weekday and off-season hours differ from peak-summer schedules
- Expect fewer local-service hours for ferries, tours, and some seasonal businesses in winter
