🌦️ BAJA CALIFORNIA — June 2025
June in Baja has been one wild ride. Foggy coastlines one minute, triple-digit inland heat the next. Here’s a clear, fun breakdown of what’s driving these swings—and what they spell for us in Baja.
Fog at Dawn, Sunshine by Noon
Thanks to the cold California Current, coastal towns like Ensenada and Rosarito are waking up to classic “June Gloom.” Thick marine fog envelopes the coast overnight, breaking up by afternoon. Mornings often feel brisk—perfect for a hoodie—but those clouds usually vanish by 10 a.m. .
Inland Heatwave: When the Sun Turns Up
Step inland, and things get sweaty fast. Places like Mexicali are hitting mid-90s to over 100°F. That’s a result of a shrinking marine layer and a high-pressure ridge pushing hot air into the valleys. NOAA data shows this is part of a wider trend of early-season heatwave conditions from mid-June to July .
Why Climate Change Matters
It’s no coincidence. Scientists warn global warming is raising these extremes—boosting inland max temps and intensifying coastal fog layers. Recent Mexican heatwaves were 1.5 °C hotter and 35–200 times more likely due to climate change .
Pacific Storms Stirring the Pot
June 2025 isn’t your usual early season. Tropical Storms Barbara and Cosme spun up near Mexico between June 8–11—right on Baja’s doorstep—causing high surf and choppy seas . Then came Hurricane Erick, the earliest major hurricane on record to make landfall—in Southwestern Mexico—peaking as a Category 4, then walloping Oaxaca by June 19 .
Though Erick made no direct landfall in Baja, it stirred splashes and moisture offshore—and hinted at a stormier season ahead .
A March Cold Front Preps June
Flashback to March: Two strong cold fronts slammed Baja, whipping up 50–70 km/h winds and rough seas, per CONAGUA . Those storms kick-started a shift in the air column, lowering humidity inland and paving the way for heat domes later. Combine that with early tropical systems, and you get the perfect storm of temperature swings.
🧭 What This Means for You
| Coastal Life | Inland Living |
|---|---|
| Bring a sweater—June fog is no joke. | Avoid midday sun—it’s scorch city. |
| Boaters: expect seas up to 3 m; check CONAGUA charts. | Stay hydrated—temps over 45 °C reported in parts. |
| Fog may slow traffic, but no red alerts so far. | Watch for heat advisories—but rainfall’s still low. |
Weather Tips for Surviving Baja’s Wild June
