A coastal fishing town near Zihuatanejo, known for a shrine to Christ that draws pilgrims, Petatlan experiences a climate typical of Guerrero, where Pacific hurricane season -- Guerrero sits directly in the path of major Category 4-5 storms governs most rainfall.
Practically, that translates into catastrophic hurricane landfall and mountain-highway landslides as a real factor for Petatlan, something residents plan around rather than get caught by.
Behind the Petatlan rain map sits CONAGUA data, refreshed on a 5-minute cycle. That means the map tracks actual precipitation over Petatlan, not a statewide estimate.
Petatlan follows the same rainy-season rhythm as the rest of Guerrero, with storm frequency rising sharply during the peak months.
For the remainder of the year, Petatlan sees noticeably calmer weather, in keeping with the broader Guerrero pattern.
