Spring is one of the most comfortable times to visit Riverside. Daytime highs average in the mid-70s°F with cooler nights, making downtown walking, guided Mission Inn Museum tours, and visits to nearby museums pleasant.
This season also aligns with local festivals and the university calendar, so expect active downtown streets and restaurants but not the high heat of summer.

- Good for: Mission Inn Museum tours, Riverside Art Museum, walking to the Fox Performing Arts Center
- On-site benefits: heated outdoor pool and Jacuzzi are open year-round (6:00 AM–11:00 PM) and spa treatments at Kelly’s Spa are available

June–August: Summer — hot days, good for pool and spa-focused stays
Summer in Riverside is hot and dry; the hot season runs roughly late June through late September with average highs often above 89°F and August typically the hottest month. If you travel in summer plan indoor breaks or pool time in the heat of the day.
The Mission Inn’s year-round heated outdoor pool and Jacuzzi (open 6:00 AM–11:00 PM) and Kelly’s Spa give easy ways to cool off or relax indoors when temperatures peak.
- Tip: schedule outdoor activities for morning or late afternoon to avoid peak heat

September–November: Fall — warm afternoons, harvest events nearby
