San Diego’s coastline promises a blend of misty mornings and sunny afternoons for the perfect laid-back summer vibe this week.

San Diego, get ready for a slight twist in your famously steady weather pattern — locals may want to double-check their picnic and surf plans over the next few days as coastal clouds linger longer than usual.

While the city’s beautiful June gloom is still living up to its name, a gentle warm-up is in the cards with plenty of afternoon sunshine to brighten spirits. Here’s a breakdown of what you can expect for the next three days, so you don’t get caught off guard on your morning jog or sunset stroll.

What does it mean for you?

Monday will greet you with the typical marine layer, so don’t be surprised if the beaches look more London than SoCal before noon. By mid-afternoon, expect the sun to break through, with pleasant warmth perfect for an afternoon patio lunch.

Tuesday sees slightly more fog in the early hours but turns into a postcard San Diego day by lunch — ideal for surf sessions or an early evening run along the bay. Zero chance of rain means you can ditch the umbrella.

Wednesday shapes up to be the warmest of the trio, so if you’re thinking about a midweek beach day or a hike up Torrey Pines, this might be your sweet spot. Bring sunscreen; the UV index will edge higher as the marine layer retreats earlier than usual.

Locals know San Diego loves to surprise with these subtle shifts — so layering up in the morning and peeling off by lunch remains the local style hack.

Enjoy the week, and keep an eye on the sky — even our sunshine city likes to remind us who’s boss now and then.
