The weather in San Diego is a major reason why the city is one of the nation's most popular vacation destinations. Ask a San Diegan where his or her umbrella is and odds are that they don't have a clue... if they even have an umbrella to begin with.
With so many outdoor activities to choose from, it's important to mention how this list was narrowed. You won't find shopping listed since the majority of shopping malls and districts are outdoors to begin with. Just know that if the weather is great--or even it if isn't--retail therapy al fresco is always a possibility.
With 70 miles of beaches each offering different amenities and experiences, it could have been easy to make this an entire list dedicated to sand and surf. In fact, some residents might argue that's the right thing to do. However, La Jolla Shores Beach is a perfect place to learn how to surf, launch a kayak or let the kids run around while Coronado Municipal Beach is another popular choice for calm water and expansive sand. The remainder of the activities listed provide fantastic photo, picnic and educational opportunities for all ages.
The weather averages 70 degrees year-round though it's important to mention that "May grey" and "June gloom", really does mean that the sun hides behind a marine layer often during these months, though shorts are still prevalent.
