Mexico faces Sahara dust plume and July thunderstorms

A dust plume from the Sahara Desert is expected to cross the Atlantic and reach Mexican territory in July, bringing dry, warm air that will lower humidity, reduce rainfall in many regions and raise temperatures up to 46 °C in parts of the country. Meteorologists warn that while dust concentrations are low, the particles can irritate eyes, throat and nasal passages, especially for vulnerable groups, and advise staying hydrated and limiting sun exposure.

At the same time, the National Water Commission forecasts moderate to strong rains and thunderstorms for Oaxaca beginning 1 July, with heavy downpours, lightning, gusty winds and possible hail in coastal, Sierra Sur and Mixteca areas. The storm system will also generate elevated sea waves and strong rip currents along the Oaxaca coastline, prompting local authorities to urge residents and tourists to follow civil‑protection directives.
