Cabo San Lucas in May runs Pacific-Mexican dry shoulder season. SMN (Servicio Meteorológico Nacional) Los Cabos data put afternoon highs at 32°C / 90°F and overnight lows at 17°C / 63°F with 0 rain days; UV index 11 (extreme), humidity 55% (dry compared to Cancún's Caribbean 75%). The 12°C / 22°F diurnal swing is the Cabo signature — pack a pashmina or light cardigan even in May for the 17°C / 63°F Médano Beach evening breeze and the Pedregal hillside cooler nights. The dressing register splits two: the resort imports (Tory Burch, Lilly Pulitzer Palm Beach 1959, Tommy Bahama, Heidi Klein swimwear, Eres swimwear at the Esperanza, Mar Adentro, One&Only Palmilla, Las Ventanas al Paraíso) for daytime + Mexican heritage (Pineda Covalín founded Mexico City 1996 — silk-printed scarves citing Mexican folk-art motifs; Carla Fernández founded Mexico City 2000 — handwoven heritage with Mexican artisan collectives) for evening at Edith's, Flora Farm, El Farallon. The Marina Cabo San Lucas anchors sportfishing; El Arco (the iconic granite arch at Land's End where Pacific meets Sea of Cortez) is the recognized sunset-cruise destination. Reef-safe sunscreen not legally mandated in BCS but Santa María Cove snorkel operators enforce mineral-only; pack zinc-based for the Cabo Pulmo National Park (UNESCO Bisbee's Black & Blue territory). Spring break (mid-March through mid-April) ends; May is the calm before peak summer rates climb in June.
Cabo May is the dry-Pacific shoulder — Médano Beach at peak walking weather, the El Arco granite sunset cruise at calm seas, the San José del Cabo Art District Thursday-night Art Walk landing the Pineda Covalín spring collection. Linen + huaraches + pashmina for the night drop.
The capsule
- Lightweight cotton sundress or linen midi — SMN Los Cabos logs 32°C / 90°F afternoons through May with 12-knot Pacific trade winds and 55% humidity (dry compared to Cancún). Cotton in coral, ivory, or sand for the daily Médano Beach walk and the Marina shopping; linen in oat for the Edith's (Cabo San Lucas, the heritage Mexican-fusion fine dining) sunset reservation. Skip rayon — the dry Pacific air still wrinkles at midday.
- Linen wide-leg trousers or cotton shorts — Daily wear at the Marina Cabo San Lucas, the San José del Cabo Art District (the heritage Thursday-night Art Walk runs 5pm-9pm, November-June), and the Cabo Pulmo National Park drive. Linen in flax for the Flora Farm farm-to-table reservation (San José del Cabo, the heritage organic-farm restaurant since 2009); cotton shorts for the Médano paddleboard morning. Skip black — heat-absorbing in 32°C / 90°F afternoons.
- Leather huaraches — Mexican heritage sandal — Mexican leather huaraches (the heritage hand-woven leather sandal — local San José del Cabo and Todos Santos artisans sell at the Art District for $40-80, Mexico City brands like Pineda Covalín stock the polished version $150+) in cognac or natural for the Marina cobble walking and the Médano Beach restaurant runs. Skip flip-flops at every recognized restaurant — huaraches are the local-correct casual.
- Swim + cotton cover-up + sun shirt — Pacific Sea of Cortez at 23°C / 73°F per SMN — cooler than Cancún Caribbean. Cover-up in white or pastel for the Médano Beach swim and the Santa María Cove snorkel boat (operators enforce mineral-only sunscreen); UPF 50 long-sleeve sun shirt for the Cabo Pulmo National Park snorkel — UV index 11 burns shoulders in 20 minutes.
- Pashmina or light cardigan — Pacific evenings drop the Médano restaurants to 19°C / 66°F and the Pedregal hillside (200m / 660ft elevation) to 16-18°C / 61-64°F. Cotton or merino in ivory layers under the linen midi for the El Farallon (Pedregal cliff dining at the Resort at Pedregal — the heritage cliffside seafood) sunset and the One&Only Palmilla evening.
- Wide-brim sun hat + polarized sunglasses + SPF 50 — Pacific UV index 11 (extreme) by 10am. SPF 50 (mineral preferred for snorkel days) and a wide-brim sun hat for the El Arco sunset cruise (the Pisces Yachts catamaran is the recognized operator); polarized lenses cut Pacific glare on the Médano paddleboard morning. The Sea of Cortez sunlight reflects sharper than Caribbean — pack zinc-based for snorkel days even though BCS doesn't legally require it.
- Pineda Covalín or Carla Fernández silk — for evening — Pineda Covalín (Mexico City 1996 — silk-printed scarves citing Mexican folk-art motifs, Day-of-the-Dead patterns, Yucatecan textile patterns) and Carla Fernández (Mexico City 2000 — handwoven heritage with Mexican artisan collectives, the recognized Mexican-couture-with-craft heritage) hold the Mexican heritage register at evening. The El Farallon, Edith's, Flora Farm, Acre Resort, El Merkado dinners read with the heritage scarf or the Carla Fernández linen-and-rebozo dress.
- Margaritaville-style or Tommy Bahama Hawaiian shirt — for casual evening — The Marina Cabo San Lucas casual restaurants (Solomon's Landing, El Squid Roe, Cabo Wabo Cantina — the heritage Sammy Hagar bar since 1990) read Tommy Bahama (Florida-popular Hawaiian-shirt heritage) or local guayabera (the Mexican-Caribbean men's shirt — pleated front, four pockets, worn untucked). Skip the Cabo Wabo at evening if you don't like the spring-break-extension crowd; the Marina restaurants run more polished.
