Spring and autumn are by far the best times to visit Red Bluff. Summers are brutally hot — July and August routinely top 100°F (38°C) with little relief at night — and the smoke from California wildfires can be heavy. Winters are mild but wet, with the Sacramento River frequently in flood.
The Red Bluff Round-Up rodeo, held in April, is the town's largest annual event and draws crowds of cowboys and visitors from across the West.
