Forecasters track three low-pressure zones in the Pacific as BCS mixes heat and heavy rain on August 10
None of the systems poses an immediate threat to the peninsula, but the state is entering the most active stretch of cyclone season.
Mexico's National Meteorological Service is monitoring three low-pressure zones in the Pacific Ocean on August 10, 2026, none of them an immediate threat to Baja California Sur. The closest sat roughly 3,465 kilometers west-southwest of Cabo San Lucas, with a 30% chance of becoming a tropical cyclone within 48 hours and up to 90% within seven days.
Given that distance, the system implies no direct short-term impact on the peninsula. Even so, August opens the most active period of the Pacific cyclone season, which in the state runs through November.
For this Monday, according to the official forecast, a heat wave overlaps with moisture from the Mexican monsoon across Baja California Sur. Highs of 35 to 40 °C are expected alongside rainfall that in isolated spots could reach up to 50 millimeters, with lightning over the Sierra de La Laguna and nearby areas.
The mix of hot ground and scattered storms is what triggers sudden surges in the arroyos (dry streambeds), the main hazard for residents during these months. State Civil Protection stresses every season not to cross streams or fords with running water, even when they look shallow, and not to park vehicles in their channels.
As a practical guide, authorities advise keeping documents and medicines handy, identifying the nearest temporary shelter, and following only official notices from the weather service and Civil Protection, avoiding unverified chain messages. The cyclone tracking update is posted several times a day on the meteorological agency's portal.
The municipalities under this heat-and-scattered-rain pattern are La Paz, Los Cabos, Comondú, Loreto and Mulegé. Residents are advised to stay hydrated and avoid midday sun because of the heat wave, while taking extra care when driving during storms.
