UC San Diego
UC San Diego sits on the coastal bluffs of La Jolla, a huge research university split into eight residential colleges — first-years are admitted into one, and it becomes their neighborhood, dorm cluster, and dining hall for the first two years. The Tritons run in blue and gold, Geisel Library rises like a spaceship over the eucalyptus, and the Pacific is a short walk down the hill.
What to wear in La Jolla, month by month
This corner of the country breaks every generic packing list. It is not about surviving cold — it is about staying dry through a long gray winter and a famously short, beautiful summer.
| Move-in (Sept) | 66–76°F | Warm, bright, and dry — classic San Diego, with cool ocean-air evenings. No A/C needed; a fan handles the odd warm afternoon. |
| Oct–Nov | 58–72°F | Mild and mostly sunny, the water still swimmable early on. Tees by day, a light layer after sunset. |
| Dec–Feb | 48–66°F | The 'winter' — cooler and the year's only real rain, but no cold. A rain shell and a hoodie beat a parka; it never snows. |
| Mar–Apr | 52–68°F | Mild spring, a few gray-marine mornings that burn off by noon. Layers and a light jacket. |
| May–Jun | 58–70°F | 'May Gray' and 'June Gloom' — a low coastal overcast most mornings, then mild and pleasant. Still layers weather. |
What UC San Diego lets you bring
- A fan — the halls have no A/C, and a handful of warm weeks each fall and spring earn it
- Layers and a light jacket — coastal nights are cool year-round even when days are warm
- A bike, skateboard, or scooter — the campus is big and spread across neighborhoods
- Twin XL bedding (confirm your specific hall)
- UL/ETL power strip with a built-in circuit breaker — not a bare extension cord
- Damage-free wall hangings like Command strips — no nails or screws
- Low-draw LED desk and task lamps
- A fan, a reusable water bottle, and UL-listed electronics
- Open-coil / open-flame cooking: toasters, toaster ovens, air fryers, hot plates, electric grills, sandwich makers
- Candles, incense, wax warmers, and anything with an open flame
- Halogen lamps
- Extension cords without a breaker; outlet splitters and multi-plug adapters
- Space heaters and personal A/C units (unless your school provides/approves them)
- Hoverboards, e-scooters, e-bikes, and other e-mobility devices
- Weapons of any kind — including decorative — and fireworks
- A/C units — not permitted in the residence halls
- Microwaves in standard residence-hall rooms (fine in apartment units with kitchens)
- Candles, incense, halogen lamps, and space heaters
- Hot plates, grills, and toasters in non-kitchen rooms
These come from UC San Diego's official housing pages and cover the essentials plus the genuinely local rules. Double-check the current official guidance before you buy — policies and renovations change every year.

Where you'll live at UC San Diego
The eight colleges
UC San Diego's defining feature: every undergraduate belongs to one of eight residential colleges, and first-years live in their own college's dorm neighborhood. You don't pick it — you're assigned, and each college has its own general-education requirements, dining hall, traditions, and personality. Housing is guaranteed for two years, and most first-years are in doubles or triples with community bathrooms (some colleges offer apartment-style units). Here's the lay of the land.
The original college (1964) on the southwest side near the beach path — a demanding, broad 'Renaissance' general-education core, and eight multistory residence halls (Argo, Blake, Fleet and others) around Revelle Plaza, in doubles and triples with some singles.
The free-spirited college with the lightest GE requirements — first-years fill the Tenaya and Tioga high-rise residence halls around a central green, mostly doubles and triples.
Built around social justice and the 'scholar and citizen' ideal — first-years live in the new Ridge Walk Living and Learning Neighborhood apartments on the north end of campus.
An internationally focused college on the northeast rise, with residence-hall suites of doubles and triples bordering a community green and Café Ventanas.
'Toward a life in balance,' popular with engineering and CS majors — residence halls overlooking the UCSD Ecological Reserve, plus apartments near Canyon Vista.
Themed around culture, art, and technology, housed in three modern buildings at the North Torrey Pines Living and Learning Neighborhood, with suite lounges and kitchenettes.
A climate-and-global-themed college whose modern apartments — many with full kitchens and ocean views — sit at the north end of campus.
UCSD's newest college, focused on community engagement and social justice, with a mix of residence-hall and apartment units near Revelle.
