What To Pack

For the warmest days, pack short-sleeved shirts and lightweight pants or shorts, as casual attire is common throughout San Diego.

If a beach visit is in your itinerary, don’t forget your swimsuit. Additionally, sunscreen is a necessity in the sunny San Diego climate.

After enjoying the beach, getting sand off your feet can be a challenge. Consider packing baby powder or cornstarch to make this task easier. Simply sprinkle it on your skin and watch the sand brush off with ease.

As temperatures can drop quickly near the coast, it’s advisable to bring a mid-weight jacket or layers for added warmth.

If you’re interested in hiking, be sure to include active clothing and appropriate footwear in your luggage.

August Travel Tips

  • August sees high hotel occupancy rates in San Diego, so it is wise to reserve accommodations as early as possible to secure preferable rates and availability.
  • When large conventions take place, hotel demand in the Gaslamp and downtown areas increases. To avoid these peak times, consider consulting a convention calendar for optimal travel dates.
  • This time of year, beaches may experience “red tides,” which are caused by rapid algae growth. Swimming during these periods is not recommended for safety.
  • Despite expectations of bright sunshine, early August can sometimes bring overcast weather, known as “Fogust,” particularly along the coastline.
  • San Diego’s warm evenings offer excellent opportunities for outdoor activities, ensuring enjoyment well into the night.
  • No matter the season, planning ahead can enhance your enjoyment in San Diego and help avoid common travel pitfalls.
