What to Wear in San Diego in May
May in San Diego is defined by 'May Gray' — a marine layer that keeps mornings overcast and temperatures at a mild 61°F before burning off to reveal sunny afternoons reaching 73°F along the Balboa Park mesas and La Jolla Cove. Light layering is the San Diego May strategy: a denim jacket or linen blazer over a sundress for mornings, shed by early afternoon on clear days. With just one rainy day typical in May, the only weather challenge is the morning chill.

Based on typical May conditions in San Diego. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
San Diego in May ushers in pleasantly mild weather, characterized by comfortable temperatures and the iconic "May Gray" phenomenon. You can expect average daytime highs to range from the mid-60s to low 70s°F (18-22°C), while evenings and early mornings typically settle into the high 50s°F (14-15°C). The distinguishing feature of May is often a thick marine layer or fog that hugs the coast in the mornings, lending a cooler, overcast start to the day. However, this usually burns off by midday, revealing abundant sunshine and blue skies. Precipitation is exceptionally rare in May, so you can confidently leave the heavy rain gear at home, as the region experiences very little rainfall this time of year. The key to comfortable dressing in San Diego this month is strategic layering. Begin with breathable basics like t-shirts or light long-sleeved tops. Always carry a versatile outer layer such as a denim jacket, light cardigan, or a stylish bomber jacket to combat the morning chill and evening breezes, especially near the ocean. For bottoms, jeans, capris, light trousers, or flowy skirts and dresses are perfect. Comfortable walking shoes are a must for exploring, and don't forget sunglasses for when that glorious sun breaks through. While the ocean water is still cool, pack swimwear if beach lounging or hotel pools are on your agenda. This strategy ensures you're prepared for the cool coastal mornings and warm, sunny afternoons.
