This guide breaks down exactly what to expect from Cabo's weather in July. We'll cover temperatures, rain patterns, ocean conditions, and how all of it affects your plans. Whether you're weighing water activities, wildlife encounters, or simply deciding what to pack, you'll find the specifics here. By the end, you'll know if July fits what you're looking for and how to make the most of it.
What's the Average Temperature in Cabo San Lucas During July
July delivers consistent summer heat across Cabo San Lucas, with average daytime highs around 91°F (33°C) and overnight lows settling around 77–79°F (25–26°C). That 12–14°F daily swing means mornings start comfortably, afternoons bring full-strength sun, and evenings cool off enough for outdoor dining.
Expect roughly 11 sunshine hours per day, giving you plenty of daylight for both land and water adventures.
How Hot Does It Get in Cabo San Lucas in July
The thermometer tells one story, but your body tells another. While air temperatures peak around 91°F in the early afternoon, humidity hovering near 70% pushes the heat index closer to 104°F. Mornings tend to feel like dry heat, but by late afternoon, the air turns noticeably sticky.
Coastal breezes near the Marina district waterfront and beaches take the edge off, which is why water-based activities during midday feel more like relief than compromise.
Is It Cold in Cabo San Lucas in July
Cold weather simply isn't part of the equation in July. This is Cabo's warmest stretch of the year, and even the coolest moments (early mornings and late nights) stay in the upper 70s°F. Leave the layers, fleece, and long pants at home.
The only chill you might encounter is aggressive air conditioning inside restaurants and hotel lobbies, so a light cover-up works double duty if you're moving between indoor and outdoor spaces.
What's the Temperature Like at Night in Cabo San Lucas in July
Evenings in Cabo during July settle into a comfortable 77–79°F, warm enough that you won't need a jacket walking through the Marina district or sitting down for a late dinner. The humidity eases slightly after sunset, and any lingering coastal breeze makes the air feel pleasant rather than heavy.
It's the kind of weather that extends your day naturally, whether you're strolling through town or watching the last light fade over the Pacific around 8 PM.
Is the Water Warm Enough to Swim in July
July's ocean temperatures are some of the best you'll find all year, ranging from about 73°F in early July to 84°F by month's end as the Sea of Cortez steadily warms. That progression means comfortable swimming from day one, with conditions only improving as the weeks pass. No wetsuit needed, just a swimsuit and, if you're spending extended time in the water, a rash guard for sun protection rather than warmth.
Scuba diving conditions are particularly strong, as underwater visibility improves dramatically in mid-July, often reaching 30 to 60 feet. These warm temperatures mean kids and adults alike can stay in the water for long stretches, making midday ocean time the perfect counterbalance to peak afternoon heat.
Does It Rain in Cabo San Lucas in July
July brings very little rain to Cabo San Lucas. The month typically sees only one to two rainy days total, and even those tend to be brief. When showers do arrive, they're usually quick 15-minute bursts in the late afternoon or evening, the kind that clear out as fast as they roll in, leaving blue skies behind.
Morning and early afternoon hours stay reliably dry, so you can plan outdoor activities with confidence during the first half of each day.
How Much Rain Should You Expect in Cabo San Lucas in July
Total rainfall for the entire month of July averages just 12–20mm (roughly half to three-quarters of an inch). To put that in perspective, that's about one-quarter of peak rainy season levels.
The pattern matters as much as the amount: rather than steady drizzle, July's rain falls in isolated late-afternoon episodes that pass quickly. Most days see zero precipitation, and flights and beach plans go uninterrupted throughout the month.
Is July Part of the Rainy Season in Cabo San Lucas
Technically, yes. July marks the very beginning of Cabo's rainy season, which officially starts around July 9 and extends into January each year. However, July represents the early, mild phase, receiving roughly one-third of what arrives later in summer, and even less compared to September totals.
That positioning makes it a strategic window for travelers who want off-season pricing and more availability without the heavier rains that come later.
Should You Worry About Hurricane and Storms in Cabo San Lucas in July
July falls within the Eastern Pacific hurricane season, but the risk is statistically low. Only 10 tropical cyclones have affected the Baja California Peninsula in July since comprehensive record-keeping began, compared to 56 in September. Modern forecasting provides three to five days of advance notice for potential impacts.
Travel insurance that covers weather-related changes is always a smart move during summer months.
Is It Windy in Cabo San Lucas in July
July is one of the calmest months of the year in Cabo, with average wind speeds of just 8.0 mph from the northwest. That translates to minimal surface chop, smooth conditions for boat tours, and beach days free from sand-blasting gusts.
Mornings are especially still, with light afternoon breezes picking up later. For anyone prone to seasickness, July's calm seas are a genuine advantage over windier winter months.
What Wildlife Shows Up in Cabo San Lucas in July
July is a standout month for marine life in Cabo, driven by the warming waters of the Sea of Cortez. The warmer temperatures draw an impressive cast: giant manta rays hit their peak season, silky and hammerhead sharks move into the area, and sea lions are mid-breeding season. Meanwhile, sea turtle nesting begins along local beaches, with five species of sea turtles present through December.
Year-round dolphin sightings are common near reefs and underwater canyons, while sperm whales pass through the Sea of Cortez during this period. The notable absences are humpback and gray whales, which fuel winter whale watching between November and April, and January and March, respectively.
Does the Weather Affect Tours in Cabo San Lucas During July
Tours rarely face cancellations during July. The brief, predictable rain pattern means operators adjust timing and location rather than scrapping itineraries. Morning departures are strongly preferred across water-based activities, taking advantage of the calmest seas and most comfortable temperatures.
An interesting counterpoint to rainy-season concerns: brief showers can actually clear the water, creating some of the best conditions for snorkeling and diving.
What to Bring for Cabo San Lucas in July
Weather determines everything you pack. July's conditions in Cabo San Lucas mean you'll want lightweight, breathable fabrics, like linen, cotton, and quick-dry materials, along with serious sun protection.
The UV index reaches 11+ (Extreme), so a wide-brimmed hat, polarized sunglasses, and sun-protective clothing are essential. A light packable jacket handles both the occasional brief shower and overly air-conditioned restaurants. Pack multiple swimsuits since humidity slows drying time.
Best Things to Do in Cabo San Lucas in July
July brings specific advantages to Cabo San Lucas. Warm, clear water opens up exceptional snorkeling and diving, while calm seas make boat-based activities consistently enjoyable. Giant manta ray sightings peak this month, and the beginning of sea turtle nesting season adds wonder to time on the coast. Summer timing means more availability and breathing room on popular activities, and extended daylight until 8 PM stretches every day further.
