White Linen Blazer Day
A white linen blazer over matching wide-leg linen trousers and a blue collarless blouse stays entirely polished through warm rain. Slide sandals and gold aviators make it feel like summer despite the drizzle.
What to Wear in San Diego in March
In March, San Diego averages highs of 68°F and lows of 54°F with about 6 rainy days — mild Southern California coastal weather with morning marine layer and pleasant afternoons. Balboa Park's 1,200 acres of gardens and museums are excellent in March's comfortable temperatures before summer crowds. A light jacket for mornings handles the coastal marine layer; the afternoons are warm enough for light fabrics.

Based on typical March conditions in San Diego. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
March in San Diego is mild and pleasant — highs averaging 68°F, lows at 54°F, and 6 rainy days that are often just passing fronts rather than sustained rain. San Diego's famously consistent climate means March doesn't feel dramatically different from February or April; the city's year-round pleasant-weather reputation is well-earned. Balboa Park's 17 museums, gardens, and the San Diego Zoo are excellent in March without summer's crowds. La Jolla Cove and the Pacific Beach boardwalk are comfortable for outdoor walking in light layers. San Diego's beach-casual and active-lifestyle aesthetic runs year-round — March is no exception. Light layers handle the 14°F daily swing: a light jacket or zip fleece for the morning marine layer that keeps the coast around 54°F until midday, with the jacket removed for comfortable 68°F afternoons. Comfortable shoes work for Balboa Park's extensive walking paths, and sandals handle Pacific Beach boardwalk activity. The 6 rainy days are usually passing — a compact umbrella is useful but not critical.
Curated Looks
Casual
Linen Under Rain Jacket
A black rain jacket over ivory linen trousers refuses to look sloppy in warm rain. Espadrilles and a crochet bucket hat keep the warm-weather mood alive below the waterline.
Chic
Blush Jacket Tortoise
A blush cropped jacket over a white linen blouse and ivory wide-leg trousers refuses to look heavy in warm rain. Tortoiseshell cat-eye sunglasses are the editorial punctuation.
Cozy
Parka and the Ivory Mules
A black longline parka over a crewneck sweatshirt in warm rain has a deliberateness that works. Ivory satin mules and a cream beanie are the contrasts that make it.
Cute
Double Denim Rainy Day
A light wash denim jacket over a denim mini skirt makes a strong case for double denim in warm rain. The black square neck top underneath adds structure.
Formal
Black Blazer Pleated Rain
A black blazer over an ivory blouse and pleated maxi skirt in warm rain is complete formal coverage. Black mule heels are the practical formal choice when espadrilles are off the table.
Sporty
Yellow Jacket Biker
A yellow hooded rain jacket over biker shorts and a longline tee handles warm rain with high-visibility attitude. Ivory pointed-toe mules are the surprising finishing note.
