Water and safety in Sayulita

The official beach tests, and what they mean

Cofepris, Mexico's federal health-risk agency, tests seawater at tourist beaches before the three holiday periods: Semana Santa, summer and winter. Nayarit's state agency, COESPRISNAY, takes the samples, which for Sayulita come from one point near the middle of the main beach. A beach counts as fit for swimming when enterococci, bacteria that point to sewage, average 200 or fewer per 100 ml over several samples.

Sayulita failed the Semana Santa 2025 round, at 268, after a drainage fault in town. The state cleared it in mid-April once repairs were made, and Cofepris confirmed it that July. Every round since has passed: 66 in summer 2025, 11 in winter 2025, 10 before Easter 2026 and 32 in the latest, summer 2026, sampled 15 to 22 June. San Pancho, the next beach north, usually reads lower still.

Each result is a snapshot from a week or so of sampling, not a daily reading. Our Learning to surf page keeps the round-by-round record, and Surf & weather shows the latest result beside today's sea.

The river mouth after rain

The Sayulita river reaches the sea at the north end of the main beach, and that's where the water is most likely to be dirty. In the rainy season, roughly June to November, heavy rain sends runoff down the river and into the bay for a while afterwards.

Pro Sayulita, a local nonprofit, pays for its own monthly tests at two points. They aren't official and measure a different indicator, but the 2025–26 pattern is plain: the river-mouth end reads far higher than the main beach after the rains, and in July 2026 both points ran high.

So stay out for a few days after heavy rain, keep well south of the river while it's running into the sea, and skip any water that looks brown or smells. Sources disagree on exactly how long to wait, so if in doubt, ask at a surf school.

Rips, shore break and the flags

Rip currents are the main danger on this coast. Canada's travel advice, updated in October 2026, notes that they're common in Mexico and that beaches are often unsupervised, so don't count on a lifeguard. In Sayulita the north end of the bay has the stronger rips and shore break; the south end and Playa los Muertos are gentler. Bigger swells, more common in the rainy season, make everything stronger.

The flags at the beach entrance describe the surf, not the water quality: green is calm, yellow means take care, red means no swimming and black means the beach is closed. If a rip pulls you out, don't fight it: swim parallel to the shore until you're free, then angle back in.

Beginners should take a lesson and stay out of the zone where the waves break. Shuffle your feet in the shallows, as stingrays are reported in the warmer months.

Drinking water and ice

Don't drink the tap water. Rentals usually supply garrafones, 20-liter jugs of purified water, for drinking and cooking, and corner shops sell bottles. Restaurants and cafés in town use purified water and ice.

Brushing your teeth with tap water is fine for most people, but use purified water if your stomach is sensitive. At street stalls, ask about the ice if you're unsure.

Sun, heat and mosquitoes

It's warm all year, and the summer months add heavy humidity. The midday sun on the sand is strong, so plan for shade, a hat and plenty of purified water, and a rash guard if you're surfing.

Mosquitoes are at their worst in the rainy season and bite by day. Dengue is present in Nayarit: the state had 72 confirmed cases by late June 2026, most of them around Tepic. Use a strong repellent, cover up at dawn and dusk, and keep screens shut. If you get a high fever, a bad headache or aching joints, see a doctor, and take acetaminophen rather than ibuprofen or aspirin until you've been checked.

Storm season and official warnings

Most eastern Pacific storms reach this coast between June and November, with the peak in September and October. Direct hits on Sayulita are uncommon; more often a storm passing offshore sends big surf, rip currents and heavy rain. Hurricane Priscilla stayed offshore in October 2025 but brought high seas to the coast, and in mid-October 2026 the US National Hurricane Center put the coast from Cabo Corrientes to San Blas, Sayulita included, under a tropical storm warning for Hurricane Trudy.

For official warnings, follow the National Hurricane Center, Mexico's weather service (SMN, part of CONAGUA) and Protección Civil for Nayarit and Bahía de Banderas. Our Surf & weather page shows any storm within 1,500 km, straight from the hurricane center's feed. When a warning is up, stay out of the sea, keep away from the river and arroyos, and follow Protección Civil's instructions.

In an emergency anywhere in Mexico, call 911.
