When the Pacific Northwest turns up the heat in July, many Portland and Vancouver homeowners assume it’s time to shut the lid on their hot tub. But here’s the truth: hot tubs aren’t just for winter. With the right settings and a few simple habits, they can be a relaxing oasis—even during a midsummer heatwave.
At Rose City Pool & Spa, we help our customers make the most of their hot tubs year-round. Whether you’re trying to cool down in Camas or unwind after sunset in Southeast Portland, here’s how to soak smart and safe this summer.
Can You Use a Hot Tub in Hot Weather? Absolutely.
While a 104°F soak might not sound appealing when it’s 90° outside, most hot tubs are adjustable—and more versatile than you think.
In fact, lowering your hot tub temperature creates a spa-like cooling effect while still delivering the benefits of hydrotherapy. During the day, it can feel like a plunge pool. At night, it becomes the perfect way to relax without overheating.
Benefits of hot tub use in warm weather:
- Relieves muscle tension after summer workouts or yardwork
- Promotes better sleep when used in the evening
- Helps reduce anxiety and stress, even in the heat
- Encourages circulation, especially when used at lower temps
The key is adjusting your routine to match the climate.
Smart Soaking Tips for Heatwave Conditions
Here in the Portland-Vancouver metro, heatwaves are becoming more frequent—and more intense. July highs often creep into the 90s, with UV index warnings and air quality advisories. But that doesn’t mean your hot tub has to sit unused.
1. Turn the Temperature Down
Set your spa between 85°F and 95°F during heatwaves. It still feels warm without being stifling—and it protects your equipment from overexertion.
2. Soak Early or Late
Plan your hot tub time before 10 a.m. or after 8 p.m. to avoid direct sun and high UV exposure. These windows offer cooler air and less water evaporation.
3. Stay Hydrated
Even light soaking can lead to dehydration in the summer. Keep a bottle of water nearby and limit sessions to 15–20 minutes during hot spells.
4. Keep the Cover On During the Day
Direct sunlight raises your water temperature and breaks down sanitizer. Use your spa cover to maintain cooler water and reduce chemical use.
5. Use Shade or Umbrellas
Install a canopy, umbrella, or pergola to provide partial shade. This helps keep your spa temperature stable and makes midday soaks more comfortable.
Don’t Ignore Summer Water Care
Warm temperatures accelerate chemical breakdown, bacteria growth, and water cloudiness. If your spa gets daily sun exposure or increased use during the summer, weekly maintenance is critical.
What we recommend:
- Test and balance water twice a week
- Shock after heavy use or parties
- Rinse filters weekly, and deep clean monthly
- Watch for foam or odor, which indicate buildup of oils or debris
Need help staying on top of it all? Our weekly hot tub/spa maintenance service keeps your system running safely while you focus on relaxing.

Protect Your Equipment from Heat Damage
While you’re managing your own comfort, don’t forget about your spa system. Prolonged heat can cause wear and tear on spa components—especially if water levels are low or the cover is left off.
Watch for:
- Low water levels from evaporation
- Faded or cracked spa covers due to UV exposure
- Pump strain or short-cycling in extreme heat
If your spa cover is sagging, splitting, or waterlogged, it may be time for a replacement. We offer cover inspections and replacement consultations across Portland and Vancouver.
→ Book a cover check to keep your hot tub protected and efficient all summer.
A Hot Tub for All Seasons—Even July
Portland evenings don’t lose their magic just because it’s midsummer. In fact, some of the best soaks happen when the sun sets late and the temperature drops to that perfect high-60s range. Whether you’re using your hot tub for recovery, relaxation, or connection, there’s no reason to shut it down when the heat rises.
With a few smart adjustments, your hot tub can continue to support your wellness routine—even during the hottest days of the year.
