Puerto Vallarta’s Sunday forecast looks calmer at street level than the wider Pacific map suggests. The city is starting June 7 with heat, humidity, shifting clouds, and only limited rain in the day’s main forecast. Still, federal forecasters are watching heavier rainfall in parts of Jalisco and two developing systems farther south in the Pacific. That leaves the bay with a familiar early rainy-season setup. Beach plans may work. The afternoon sky may still have other ideas.
Warm Sunday in the bay
Puerto Vallarta begins Sunday, June 7, with a forecast that looks calmer at street level than the wider Pacific map. Early local readings sat near 26°C (79°F), with a few clouds over the city. The day’s high is expected near 31°C, or 88°F, and the overnight low should settle around 24 to 25°C, or 74 to 77°F.
Humidity is already part of the day. A morning feed showed it at near 84 percent, with a light wind of around 4 km/h (2.5 mph) from the northeast. Another daily forecast put the afternoon wind at about 13 km/h (8 mph) from the northwest. That gives the bay a little movement in the air, not enough to erase the sticky June feel.
The forecast favors shifting clouds and sun through much of the day. It does not rule out rain. One local outlook listed a 60 percent chance of precipitation, with only about 1 mm (0.04 inches) of rainfall expected. Another kept the daily chance of rain low while still showing a heat index near 41°C (105°F) in exposed areas.
The maximum UV index is forecast at 13, which is extreme. That makes the middle of the day punishing even without a storm nearby.
The stronger rain signal is outside the city forecast
The official national forecast is wetter than the city forecast, but its strongest signal is not aimed squarely at Puerto Vallarta. Federal forecasters placed southern Jalisco under “lluvias muy fuertes con puntuales intensas,” a category equal to 75 to 150 mm of rain, or roughly 3 to 6 inches, in localized zones.
That wording is worth reading carefully. It points to southern Jalisco and nearby Pacific states, not a confirmed heavy-rain warning for Puerto Vallarta. Still, it keeps the region in an early rainy-season setup. The bay can start the day with workable skies while heavier weather builds elsewhere along the coast.
The Puerto Vallarta weather guide explains the usual June patterns. The rainy season runs from June through October, and the first part of the day often behaves differently from the late afternoon or evening. Humidity hangs around. Clouds thicken. Then a short burst can turn loud over the mountains and move toward town.
Pacific systems stay on the watch map
The Pacific is already busy for the first week of June. An earlier report by PVDN said a low-pressure system a couple of hundred miles south of Acapulco had a 90 percent chance of becoming a tropical depression within 48 hours and through seven days. The system is expected to move toward southern Mexico tonight and Monday.
The bulletin said “heavy rainfall and life-threatening flash flooding” are possible across portions of southern Mexico through early this week.
A separate system offshore of Central America also had a 70 percent chance of forming. Farther west, Tropical Depression Amanda remained well east-southeast of the Hawaiian Islands and was forecast to weaken into a remnant low by late Sunday.
A recent Pacific hurricane season guide for Puerto Vallarta made the same local point in plainer terms. Banderas Bay, Cabo Corrientes, and the Sierra Madre can influence nearby storm behavior, but water is still the city’s usual problem when storms pass close enough. Heavy rain can swell rivers, loosen hillsides, and flood low spots even when the wind is not the main event.
Monday looks wetter
Monday’s forecast turns cloudier. The high is expected near 29°C (84°F), with the low around 24°C (75°F). Afternoon showers are possible, and the chance of rain increases compared with Sunday.
Sunrise was around 6:19 a.m., and sunset is expected near 7:40 p.m. The evening should stay warm and damp. If clouds build over the hills late in the day, that will fit the season more than it will feel like a surprise.
