It's never too hot or too cold in San Diego. Winter temperatures usually hover in the 60s and daily highs in the summer rarely exceed 80°F.
Fly into San Diego International Airport (SAN), conveniently located 3 miles from downtown. If you're coming from northern California, we love the alternative scenic route by train on Amtrak (stop at Sante Fe Depot). To easily access the wider region, we recommend renting a car once you arrive. However, the many local trolleys also provide an entertaining travel option around downtown and out to nearby sights and neighborhoods.
