Quick Look by Season

Season Surface Temp (approx.) Typical Visibility Wind & Sea State Wildlife Highlights
Nov–Apr (Cool & Clear) 66–75°F (19–24°C) 40–80 ft (12–24 m) in stable spells North winds (“Nortes”) can blow; many calm windows; cooler water Whale sharks (La Paz), humpbacks (offshore), sea lions (year-round)
May–Jun (Warming & Stable) 72–82°F (22–28°C) 30–70 ft (9–21 m) Generally mellow; AM glass; light PM breeze Mobula (manta) aggregations, sea turtles, reef life
Jul–Oct (Warmest Water) 80–88°F (27–31°C) 30–80 ft (9–24 m) when stable Calmer seas overall; occasional tropical moisture Peak snorkeling comfort, pelagics in blue water, bioluminescence nights

Conditions vary by week. Your captain will shape the route and daily plan around the best windows.


Wind & Sea Patterns (What This Means for Your Days)

  • Mornings are typically calm → ideal for eFoiling, paddle laps, and easy snorkel starts.

  • Afternoons bring a predictable seabreeze → great for scenic sails, swims in protected bays, and beach time.

  • Winter “Nortes” (Nov–Mar) can kick up short-period chop; we tuck into lee anchorages and time crossings smartly.

  • Summer (Jul–Oct) generally has warmer water and longer calm spells; occasional tropical moisture dictates conservative routing.

  • Around La Paz, nighttime Coromuel breezes (late spring–summer) can cool things down; we choose anchorages accordingly.


Water Temps & Visibility

  • La Paz / Espíritu Santo area: Winter lows in the upper 60s°F; clear days can deliver excellent viz on reefs and in caves.

  • Late spring through early fall: Water warms quickly (low-80s°F common), visibility improves after bloom cycles stabilize.

  • Thermoclines are normal; a thin neoprene top or shorty adds comfort even in summer if you run cool.


Wildlife Calendar (Typical Windows)

  • Sea lions: Year-round; playful colonies make for iconic snorkel sessions.

  • Whale sharks (La Paz): Roughly late Oct–April (permit-regulated).

  • Mobula (manta) rays: Often April–July and Oct–Nov; epic schooling behavior.

  • Humpbacks: Winter–early spring offshore; acoustic treats on quiet nights.

  • Bioluminescence: Most noticeable on dark, calm summer nights.

  • Turtles, reef life: Year-round with frequent sightings.

Wildlife is wild—no guarantees, but timing and local knowledge help a lot.


Favorite Secluded Anchorages (South of Loreto to La Paz)

  • Isla Espíritu Santo / Partida: Cathedral-like cliffs, sea caves, luminous shallows, protected coves for night swims.

  • Isla San Francisco: Crescent-shaped bay with hiking ridges and glassy shallows—postcard snorkeling.

  • San Evaristo: Quiet village vibe, mangrove pockets, excellent beach picnics.

  • Isla Cerralvo (Jacques Cousteau): Blue-water edges for pelagics; choose coves for wind protection.

  • Balandra (day stop): Legendary sandbars and color; we time our visits to avoid crowds and protect the ecosystem.

Your exact route will depend on wind, swell, and your group’s priorities (eFoil sessions, scuba, snorkel, beach time).


eFoil, Snorkel & Scuba — Best Practices

  • eFoil: Max fun at sunrise in protected water; we rotate batteries and riders to keep the stoke high. Give wildlife and swimmers space; observe local speed/etiquette.

  • Snorkel: Gentle entries off the stern or from the dinghy; we target coves with current breaks and kelp/rock structure for fish life.

  • Scuba: From reef ledges to sea lion hotspots; certified divers only (or ask us about discovery dives with trusted partners). We plan dives around currents and visibility windows.


What to Pack (Charter-Smart List)

Water & Sun

  • Reef-safe sunscreen, lip balm SPF

  • Rashguard or 2–3mm shorty (winter: consider 3–5mm full)

  • Polarized sunglasses + retainer, wide-brim hat

  • Refillable water bottle

Activity Gear

  • eFoil accessories if you have preferences (we supply the essentials)

  • Snorkel mask that fits your face (boat has full sets; your own always seals best)

  • Dive computer & log (certified divers), C-card

  • Action camera, spare batteries, dry bag

Boat Life

  • Soft-sided duffel (no hard suitcases), light sweater for evenings

  • Sandals + reef-safe water shoes

  • Motion tabs/ginger (if you’re sensitive), personal meds

  • Minimalist outfits—swim/live, rinse/repeat

We take care of the big items—vessel, crew, chef, safety, gear staging, and logistics—so you can travel light.
