With a year-round average temperature of 70 degrees, we can still enjoy the outdoors in San Diego in fall. The beaches are less crowded and the sun is still out.
Tide pooling is a popular activity in fall and winter whenever there happen to be minus tides during daylight hours. Cool little sea creatures reveal themselves like hermit crabs, sea anemones, sea cucumbers, octopi and more. Two good places for this are La Jolla Shores Beach near Scripps Pier and the Cabrillo National Monument.
We also have a couple of very popular, county-wide events in fall. The first is Kids Free San Diego, which happens in October. This means that kids are free with a paid adult to various museums, theme parks, restaurants, tours, hotels and other fun activities around town (check to see if any restrictions apply). This makes fall one of the very best times for families to visit San Diego.
And, there are also Halloween and Dia de los Muertos celebrations to enjoy. So, come to San Diego in fall to enjoy good weather, less crowds, annual events and some pretty major discounts.
