There's little chance of rain in September, but evenings near the ocean can feel chilly. Bring a light to mid-weight jacket or extra layer to stay comfortable.

Otherwise, you can wear short-sleeved shirts and lightweight pants, with an extra layer for cooler days and places, but you'll find you need fewer shorts than earlier in the year.

Tips for San Diego in September

Hotel occupancy is lower in September than it was in the summer. That makes it easier to find a good rate at a hotel in your preferred area.
