Month-by-month at a glance
Below is a quick month-by-month table showing typical weather, water-park status, and who usually prefers each month. These are general patterns for Phoenix and the resort; check the resort for exact Oasis Water Park closure dates (it closes around late December/early January for enhancements).
Use this table to match your priorities: cooler outdoor activities, pool days, or avoiding monsoon storms.
| Month | Typical weather & notes | Good for |
|---|---|---|
| January | Mild days, cool mornings; water park may be closed around holiday shutdown | Golf, spa, quiet family stays |
| February | Cool to mild; sunny afternoons | Hiking, golf, outdoor dining |
| March | Warm and comfortable; spring weather | Hiking, water park opens/warms up, families |
| April | Warm, low humidity | Pools, golf, outdoor events |
| May | Hotter but still dry; pool season ramps up | Water-park days, early summer travel |
| June | Very hot; dry, before monsoon rains increase | Young families at water park, early-summer deals |
| July | Hottest month; monsoon thunderstorms possible | Water-park visitors who can handle extreme heat |
| August | Hot with monsoon storms; humid afternoons | Pool and indoor-activity stays |
Best overall months: March–May and late September–November
March through May and late September through November offer the most comfortable daytime temperatures for outdoor activities around South Mountain Preserve and for using resort amenities without extreme heat. These windows are the most popular for hiking, golf, and exploring Phoenix while still being able to enjoy pools and the water park on warm days.
Expect sunny afternoons and cool mornings; these months are good for outdoor dining at Lobby Grill, walking the golf fairways, and booking spa time at the Arizona Grand Spa (note spa hours Mon–Thu 10am–5pm, Fri–Sun 9am–6pm).
- Ideal for hiking in South Mountain and day trips to Tempe or Old Town Scottsdale
- Golf course and outdoor venues are comfortable for play and events
- Water park and pools are warm (pools heated to low 80s year-round) and generally open
| Month range | Why go |
|---|---|
| March–April | Warm days, excellent hiking and golf; spring break crowds possible |
| October–November | Cooling from summer heat, good weather for pools and outdoor events |

Summer (June–August): water-park focus and heat considerations
Summer in Phoenix is hot — July is typically the hottest month — but Arizona Grand Resort & Spa stays busy because of its 7-acre Oasis Water Park, multiple heated pools, lazy river and cabana options. Pools and water-park features are heated to the low 80s year-round and poolside outlets like Oasis Bar & Grill operate during pool hours.
Monsoon season (mainly July and August) can bring dramatic afternoon thunderstorms. Those storms can affect outdoor plans but often pass quickly; the resort operates pools and the water park on a seasonal schedule, so verify hours on your travel dates.
- Best for families who prioritize water-park days and pool time
- Expect afternoon heat — plan pool time in mornings or late afternoons
- Oasis rules: children under 12 must be accompanied by an adult; Slide Canyon Tower has a 48-inch height requirement
| Tip | Action |
|---|---|
| Avoid midday heat | Use pools/water park early or late; seek shade or cabana rentals |
| Monsoon alerts | Check weather; pool operations may pause during lightning |
| Water-park access | Access is included with the Resort Fee; wristband numbers depend on room type |

Winter (December–February): mild days, quieter pools, and outdoor recreation
Winter brings the coolest mornings and mild afternoons — good for hiking, golf, and sightseeing. Pools remain heated into the low 80s, but the Oasis Water Park typically closes for a brief late-December to early-January maintenance window, so check exact closure dates before booking around the holidays.
Winter is a good choice if you want outdoor activities without summer heat: golf, walking the resort grounds, or visiting nearby attractions like Arizona Mills Mall and Tempe Town Lake are pleasant in this season.
- Best for outdoor recreation that needs cooler temperatures (hiking, golf)
- Water park may be closed around Dec 22–Jan 3 for maintenance/enhancements
- Spa and Athletic Club remain available — Athletic Club hours are Mon–Fri 5am–8pm, Sat–Sun 6am–8pm
| Winter perk | Notes |
|---|---|
| Quieter resort pools | Fewer families at peak water-park times outside holidays |
| Easier tee times | On-site 18-hole course is comfortable for winter play |
| Holiday travel | Resort may be busier during holiday weeks despite park maintenance |

Planning tips that affect when to visit
Resort operations and access affect your stay: the Resort Fee includes standard high-speed Wi‑Fi, Athletic Club access, self-parking, and complimentary Oasis Water Park wristbands (the number depends on your confirmed room type). Check whether your chosen suite type (for example Deluxe Suite, Grand Suite, or Suite, Golf View) includes the wristband allotment you need.
Check-in is 4:00 PM (rooms guaranteed by 6:00 PM) and check-out is 11:00 AM. On arrival day, guests may enter Oasis as early as 12:00 PM even if their room isn't ready. The resort does not provide an airport shuttle; use taxi or rideshare options from Phoenix Sky Harbor (about a 10–11 minute drive).
- If you want pool/time at check-in day: arrive before noon to use Oasis (subject to seasonal operation)
- Confirm Oasis Water Park dates — it closes yearly around late December/early January
- Resort is family-friendly; children are welcome though some pools (Adult Only Lap Pool) are reserved for adults
| Resort fact | What to check |
|---|---|
| Resort Fee includes Oasis wristbands | Confirm wristband count for your booked room type |
| No airport shuttle | Plan rideshare or taxi from PHX (about 6–7 miles) |
| Spa hours | Arizona Grand Spa hours vary; book treatments early |
