Ports closed, hurricane warning in force: Mexico's Pacific coast braces
What happened
The FCDO updated its travel advice for Mexico on 9 October 2026 to warn about Hurricane Simon. The advice states that Hurricane Simon is bringing heavy rain to Mexico's Pacific coast. It says the storm was forecast to intensify to a major hurricane, making landfall around Manzanillo on Sunday 11 October, then progressing through Jalisco state, including the regions surrounding Puerto Vallarta and Guadalajara. It warns this could result in life-threatening flooding and landslides, very high winds and dangerous ocean conditions. A hurricane warning is in place. Two practical lines in the advice matter most for travellers: flights could be affected, and ports have been closed. On the storm itself, the US National Hurricane Center placed Simon about 65 miles south-southwest of Manzanillo in one advisory, as a Category 4 hurricane with winds near 150 mph. A later update put top winds at 155 mph, just short of Category 5. Forecast rainfall was substantial: totals of 250 to 500 mm, with isolated amounts up to 750 mm. For context, that upper figure is roughly what some parts of the UK receive in a year, falling in a matter of days. Mexico's civil protection agency said Simon could come ashore on Sunday morning, 11 October, between La Huerta and Tomatlán in Jalisco. Other forecasts put the landfall zone between Manzanillo and Puerto Vallarta. Authorities told residents across 24 municipalities to stay indoors or reach shelters. Forecasters noted the storm could still weaken to Category 3 or 4 at landfall, and that the exact timing and landfall point remained uncertain.
Why this matters
This stretch of coast is not a remote one. Puerto Vallarta is one of Mexico's best-known beach destinations, and Guadalajara is the country's second-largest city. October sits at the tail of the Pacific hurricane season, which is exactly when a lot of people book winter sun. So there will be British travellers in the affected area right now, and more with flights booked in the coming days. The detail that catches people out is rarely the wind. It is the water. In mountainous coastal regions, the heaviest rainfall often falls inland of where the storm comes ashore, and it runs downhill fast. Flooding and landslides can cut roads a long way from the coast, in places that felt safe. That is why 250 to 500 mm of rain is the most important figure in this story, more than the wind speed. Wind damages buildings. Water strands people, closes roads, cuts power and contaminates water supplies. The closure of ports is a signal worth reading too. Authorities close ports before conditions become dangerous, not after. If you had a cruise, a ferry or a boat trip booked, assume disruption. The honest point about timing is this. As this article was written, landfall was forecast for Sunday 11 October and the outcome was not yet known. Nobody reading this should assume the worst has happened, and nobody should assume it has passed. The situation was live.
What the evidence actually says
Hurricane forecasting has become genuinely good at a few days out, and it remains uncertain about details. Both halves of that are important. What forecasters were confident about: a powerful hurricane approaching Mexico's Pacific coast, with destructive winds, life-threatening storm surge and very heavy rain. What they were not confident about: exactly where and when it would come ashore, and how strong it would be at that moment. Sources placed the landfall zone variously between La Huerta and Tomatlán, around Manzanillo, and between Manzanillo and Puerto Vallarta. Timing estimates ranged from Saturday night to Sunday afternoon. The National Hurricane Center noted Simon might weaken to Category 3 or 4 before landfall. That spread is not forecasters disagreeing out of incompetence. It is what honest uncertainty looks like a day or two before landfall. A difference of 50 miles in landfall position changes which towns take the worst of it. The practical lesson is to act on the warning area rather than the forecast dot. If you are anywhere along that stretch of coast, the useful assumption is that you might be affected, not that you probably will not be. It is also worth noting that forecast wind figures for a storm at sea describe the storm, not necessarily what your location will experience. Winds weaken over land and vary a great deal with terrain. One honest caveat about this article: at the time of writing, no post-landfall damage reports were available. The figures here are forecasts and official warnings, not an account of what happened. For the current situation, the FCDO page, the National Hurricane Center and Mexico's Meteorological Service are the sources to check, and the FCDO specifically advises monitoring both of the latter two.
Practical advice
If you are in the affected area, follow advice from local authorities and your tour operator. This is the FCDO's own instruction, and it comes first because local authorities know which roads and shelters are safe. If you are told to shelter or stay indoors, do it, and do not go to the beach to look at the sea. Dangerous ocean conditions kill people who went to watch. Move to higher ground if local authorities advise it, and treat flood water as unsafe to walk or drive through. Moving water does not need to be deep to knock you off your feet or float a car. Fill water containers and charge devices while you still have power and supply. Power cuts and water interruptions are among the most common after-effects. If you have a flight booked, contact your airline. Flights could be affected and ports have been closed, so do not travel to an airport or port without checking. Do not cancel independently before speaking to your insurer and operator. Your rights depend on the wording of your policy and on official advice, and a self-cancellation can weaken your position. Sign up for email alerts on the FCDO Mexico page so updates reach you, and monitor the US National Hurricane Center and Mexico's Meteorological Service, as the FCDO recommends. Tell someone at home where you are and check in with them. In a storm with power and phone disruption, a prearranged check-in time is worth more than constant contact. On medicines, keep what you need with you rather than in a hotel safe or a hold bag, and keep more than the trip requires. If you are delayed for days, a supply that only covered the planned stay becomes a problem. A written list of your medicines, with generic names and doses, is genuinely useful if you need help from a local pharmacy or clinic. And after any flood, treat tap water as suspect until authorities say otherwise, and avoid contact with flood water where you can.
What to know
The FCDO updated its Mexico travel advice on 9 October 2026 to warn about Hurricane Simon. A hurricane warning is in place, ports have been closed, and flights could be affected. Simon was forecast to make landfall around Manzanillo on Sunday 11 October and move through Jalisco state, including the areas around Puerto Vallarta and Guadalajara. The FCDO warns of life-threatening flooding and landslides, very high winds and dangerous ocean conditions. The storm was a Category 4 hurricane with winds near 150 mph, later reported at 155 mph, with forecast rainfall of 250 to 500 mm and isolated totals up to 750 mm. Authorities told residents in 24 municipalities to stay indoors or reach shelters. Landfall location, timing and intensity all remained uncertain, and forecasters said Simon might weaken to Category 3 or 4 before coming ashore. This article was written before landfall and contains forecasts and warnings, not damage reports. Check the FCDO page, the US National Hurricane Center and Mexico's Meteorological Service for the current position. The water is usually the bigger danger than the wind. Follow local authorities, keep essential medicines with you, and contact your airline or operator rather than your own assumptions.
