Ola de Calor

On Tuesday, August 12, 2025, Baja California Sur is facing a combination of weather conditions that require the community’s attention and caution: extreme temperatures, isolated showers, moderate winds, and elevated waves.

According to the National Meteorological Service (SMN), the day began with mostly clear skies along the coast, but cloud formation is expected by the afternoon, especially over the Sierra La Laguna and Sierra La Giganta ranges. These areas may see light rainfall between 0.1 and 5 millimeters, accompanied by lightning and gusts of wind. While the showers will be isolated, they could create hazardous conditions in mountainous zones and rural roads.

Heatwave: The Silent Risk

The forecast warns of maximum temperatures near 40 °C (104 °F) in La Paz, Los Cabos, Comondú, Loreto, and Mulegé, with even higher “feels like” temperatures due to humidity. These conditions are considered high risk for health, especially for the elderly, children, and people with chronic illnesses.The BCS Health Secretariat has issued recommendations: stay hydrated at all times, avoid direct sun exposure between 11:00 a.m. and 4:00 p.m., and watch for signs of heatstroke such as dizziness, headache, flushed skin, or disorientation.

Waves and Wind: Coastal Precautions

The SMN also forecasts waves of 1.5 to 2.5 meters along the western coast, from Punta Abreojos to Bahía Magdalena. These conditions directly affect fishermen, small vessels, and tourism activities such as boat tours or water sports.The Port Authority has urged small craft to exercise extreme caution and, in some cases, suspend trips. Winds of 30–40 km/h (19–25 mph), combined with the swell, can create dangerous currents for swimmers.

Potential Lightning in High Areas

In mountainous zones like Sierra La Laguna and Sierra La Giganta, afternoon cloud development could bring lightning activity. While rainfall would be light, lightning poses risks for hikers and rural communities. Authorities recommend suspending outdoor activities during storms and seeking safe shelter.

Why This Matters for BCS Residents

1. Personal health and safety: The combination of high heat and humidity increases the risk of heatstroke and dehydration, a recurring summer concern in the region.

2. Economic impact: Fishermen and coastal tourism providers rely on safe marine conditions; winds and waves directly affect their activity and income.

3. Visitor protection: BCS hosts thousands of tourists in August, and ensuring their safety in adverse weather is key to maintaining its reputation as a secure destination.

4. Community preparedness: Early information allows rural communities to take steps to protect people and property from storms or electrical activity.
