Swimming at river mouths requires extra caution due to meeting currents from river and ocean. Water conditions can change rapidly with tides and river flow. The mixing waters may create unpredictable currents. Local knowledge is valuable, so observe where locals swim if present. Generally safer during calm weather and lower river flows. Children should be closely supervised. The unique environment makes it better suited for wading and enjoying scenery than serious swimming.

Late afternoon and evening offer spectacular sunset views as the sun sets over the river meeting the Pacific Ocean. Summer provides warmest conditions but check river water levels after rain. Autumn and spring offer comfortable temperatures with beautiful light for photography. Early morning can be serene but misses the famous sunset views. Avoid visiting immediately after heavy rains when river flow increases significantly. Weekdays typically have fewer visitors than weekends.
