August 3–9, 2026
Heavy rain, the first paid weekday for Vallarta’s new electric buses, and a two-ship cruise day will shape the week. The most immediate concern is weather: western Jalisco could receive several rounds of heavy rain through Wednesday, testing drainage systems that struggled during last week’s storms.
A wet start to the week
The National Meteorological Service forecasts 50 to 75 millimeters of rain for western Jalisco on Monday, Tuesday and Wednesday. Rainfall could ease to between 25 and 50 millimeters Thursday, although the timing and intensity will vary considerably within the region.
Thunderstorms may bring lightning, strong wind and rapid runoff. Ponding on low streets, rising streams and localized landslides are possible where heavier cells stall. Coastal waves of one to two meters are forecast through Thursday.
The National Hurricane Center does not expect tropical cyclone formation in the eastern Pacific during the next seven days. That does not make this a quiet week of weather. Tropical moisture alone can produce damaging downpours, particularly during the late afternoon and overnight.
Sunday’s last available Puerto Vallarta beach report showed mostly yellow flags. Wildlife warnings remained around the Cuale and Pitillal river mouths, Boca Negra, and beaches near the Westin and Marriott in Marina Vallarta. Conditions and flags can change during the day, especially after storms push runoff and debris into the bay.
New buses face their first weekday test
Monday is the first normal paid weekday for Puerto Vallarta’s new electric bus system following its free introductory weekend. Nineteen buses are operating on the Ixtapa–Centro and Las Juntas–Galerías trunk routes, with a feeder serving CUCosta. The integrated fare is 11 pesos, paid with a Mi Movilidad or Única card.
Published intervals range from five to 14 minutes, and routes and arrival information are expected to appear in Google Maps. This week will provide the first meaningful look at actual weekday frequency, card acceptance and crowding. Riders should carry a charged transit card rather than assume cash will be accepted.
Avenida Federación, meanwhile, was reported more than 90 percent complete entering August. Authorities have suggested it could open during the first days of the month, but no precise opening time was confirmed before publication. Drivers should continue treating unfinished sections as active work zones.
SEAPAL had not posted a new citywide suspension early Monday. The recent interruption affecting 139 colonias was reported to be largely normalized by July 28, and work at México and Las Palmas had been cleared of traffic. No planned Puerto Vallarta-wide CFE shutdown was confirmed for this week; any power interruptions are more likely to be localized consequences of thunderstorms.
At the airport, no broader operational alert was in effect. Afternoon storms in Vallarta or at connecting airports remain the most plausible source of delays, so passengers should consult GAP’s live flight information before leaving for the terminal.
Tuesday brings the week’s largest visitor surge
Puerto Vallarta remains in the federal summer vacation period, which runs through August 30. Federal projections place average local hotel occupancy at 64.4 percent for the season, second among the destinations included in the forecast. Crowds are likely to concentrate around beaches, shopping areas, and weekends rather than remain constant across the city.
Tuesday will be the busiest cruise day. The official ASIPONA calendar lists both Navigator of the Seas and Carnival Panorama, the only cruise calls scheduled during the August 3–9 period. Expect additional taxis, tour buses and pedestrian activity around the maritime terminal, Galerías, the Marina and Avenida Francisco Medina Ascencio from early morning through the afternoon.
In Emiliano Zapata, Coco Cabaret hosts the KWC México national singing finals Monday and Tuesday. Doors open at 4:30 p.m., with performances beginning at 5. Parking is already limited around Francisco I. Madero, so late-afternoon congestion is possible without any formal street closure.
La Casetera performs at The Stage at VidantaWorld Thursday at 8 p.m., adding some northbound evening traffic near the Ameca River crossing. Saturday’s Naturally Mazcal Weekend Market runs from 10 a.m. to 3 p.m. on the eastern side of Isla Cuale, bringing a smaller increase in pedestrian activity downtown.
The drainage test comes early
The developing issue this week is whether recent drain and canal clearing can prevent another round of flooding in Ixtapa. The July 31 storm flooded homes and vehicles in Los Tamarindos, La Calma and La Mina, with water reportedly reaching approximately half a meter in some places. Authorities identified obstructed or silted drainage infrastructure as part of the problem.
The forecast gives the city little time to recover. If rainfall from Monday through Wednesday reaches the upper end of the official range, the same neighborhoods may face another immediate test. The central question is whether emergency desilting has restored enough capacity or merely postponed a larger repair that still needs to be funded and scheduled.
Standing water will also increase mosquito habitat. Jalisco has reported 102 dengue cases through epidemiological week 29, well below last year’s level, while preventive work has reached 56 colonias in Puerto Vallarta. This is the week to empty uncovered containers, clear roof drains, and report persistent pools that remain after the streets have dried.
