Hurricane Polo: what the UK's updated Mexico travel advice actually says
What happened
The Foreign, Commonwealth and Development Office updated its Mexico travel advice on 28 September 2026 to add information about Hurricane Polo. The advice states that Hurricane Polo will impact Baja California Sur on the afternoon and evening of 28 September, and is forecast to continue into Sinaloa and Sonora states over the following days. It warns of high winds, dangerous sea conditions and heavy rain, 'with risks of life-threatening flooding and landslides'. The FCDO asks travellers to monitor local and international weather updates, including from the US National Hurricane Center and the Mexican Meteorological Service, and to follow advice from local authorities and their tour operator. It notes that local authorities have published guidance on emergency preparedness and on where emergency shelters are. It also makes a point that is easy to miss: 'Post storm environments can remain hazardous, including due to damage to infrastructure, flooding, possible power outages and limited communications.' British travellers affected by the hurricane and needing consular help are directed to call the British Embassy in Mexico on +52 55 1670 3200. Separately, the advice notes that Mexico's hurricane season normally runs from June to November and can affect both the Pacific and Atlantic coasts.
Why this matters
Baja California Sur is not an obscure corner of Mexico. It includes Los Cabos and La Paz, which are popular with British holidaymakers, and Sinaloa includes Mazatlán. These are places with hotels, cruise stops and flights. The phrase 'life-threatening flooding and landslides' is not standard FCDO boilerplate. It is a deliberate escalation in the language used, and worth taking at face value. The point about post-storm conditions is the one travellers most often underestimate. The hurricane makes the news; the week afterwards does not. But that week is when roads are washed out, power is intermittent, mobile networks are patchy, water supplies may be unsafe and hospitals are stretched. People are frequently injured after a storm rather than during it, often by standing water, debris or damaged electrics. Travel insurance is the other reason this matters, and the timing is crucial. Once a named storm is forecast for your destination, insurers usually treat it as a 'known event'. Buying or upgrading a policy after that point generally will not cover disruption caused by that storm. Insurance bought before the storm was named is a very different proposition from insurance bought this week. And FCDO advice itself affects insurance. If the FCDO advises against travel to a place and you go anyway, many policies become void.
What the evidence actually says
It is important to read the advice precisely, because it is easy to over- or under-state. The FCDO has not advised against travel to Baja California Sur, Sinaloa or Sonora because of Hurricane Polo. It has added a warning and told travellers to monitor forecasts and follow local instructions. That is a meaningful distinction. The separate 'advise against all but essential travel' warnings in the Mexico advice relate to security concerns in particular states, not to this storm. The forecast element should also be read as a forecast. The advice says Polo 'is forecast to continue into Sinaloa and Sonora states over the following days'. Hurricane tracks change, sometimes substantially and at short notice. That is exactly why the advice tells you to monitor the US National Hurricane Center and the Mexican Meteorological Service rather than relying on a single statement. This is also a seasonal pattern rather than a freak event. The advice notes that hurricane season in Mexico normally runs from June to November. Anyone travelling to Mexico's coasts in those months should expect the possibility, and the FCDO separately maintains general guidance on extreme weather and natural hazards. One useful comparison in the advice: Hurricane Otis hit near Acapulco in 2023 as a Category 5 storm and seriously damaged infrastructure. Reconstruction still disrupts tourism there, and the FCDO advises against all but essential travel to Acapulco - three years later. That is a reminder that storm effects on a destination can outlast the storm by years.
Practical advice
If you are in the affected area now, follow the instructions of local authorities and your hotel or tour operator. They have local information you do not. Know where the nearest emergency shelter is before you need it. Fill water containers and charge your phone and a power bank while power is on. Stay away from the sea and from swollen rivers. If you need consular help, the British Embassy in Mexico is on +52 55 1670 3200. If you are due to travel soon, contact your airline and tour operator rather than assuming. Package holidays booked with a UK operator carry stronger protections than separately booked flights and hotels, and ATOL protection applies to many package flights. Ask specifically what the operator will do if the resort is damaged, not just if the flight is cancelled. Sign up for FCDO email alerts for Mexico so you get updates automatically rather than checking. It takes a minute on the gov.uk travel advice page. On insurance, be realistic. If you already have a policy from before Polo was named, read the natural catastrophe and travel disruption sections now. If you are buying now, ask the insurer directly and in writing whether Polo-related disruption is covered; assume it is not. On health, this is where storms catch travellers out. Carry your medicines in your hand luggage, in original packaging, with enough for at least a week longer than your trip - pharmacies close and supply chains break after a storm. Take a photograph or a copy of your repeat prescription list, including the generic drug names, because brand names differ abroad. If you use insulin or anything needing refrigeration, plan for a power cut. After a storm, treat tap water as unsafe unless authorities say otherwise, and do not wade through floodwater - it commonly carries sewage, chemicals and hidden debris. Keep cuts clean and covered. Finally, make sure someone at home has your itinerary and knows how to reach you, because communications may be limited.
What to know
UK travel advice for Mexico was updated on 28 September 2026 to warn that Hurricane Polo would hit Baja California Sur that afternoon and evening, and is forecast to move into Sinaloa and Sonora over the following days, bringing high winds, dangerous seas, heavy rain and risks of life-threatening flooding and landslides. The FCDO has not advised against travel to those states because of the storm, but tells travellers to monitor forecasts and follow local instructions. The most underrated warning is about afterwards: damaged infrastructure, flooding, power cuts and limited communications persist once the storm has passed. Practical priorities: follow local authorities, know where shelters are, check with your airline or operator before travelling, sign up for FCDO alerts, assume a policy bought now will not cover Polo, and keep a week's extra medicine in your hand luggage.
