Best Time of Year for a Funchal Catamaran Cruise

Madeira barely has a winter

The first thing to understand is how little the year moves here. The Funchal weather station, less than six kilometres from the marina, records an average daytime high of twenty degrees in January and twenty-seven in August. That is a swing of seven degrees across an entire year, in a place where a great many European visitors come from cities that swing thirty.

The practical consequence is that there is no wrong month for this trip. A catamaran cruise in January happens in twenty-degree sunshine with the boat running and the dolphins where they always are. That is not something you can say about a boat trip almost anywhere else in Europe, and it is the main reason Madeira has a year-round season at all.

What actually changes: the sea

Since the air temperature barely moves, the real variable for this particular trip is the water, because of the swim stop. The sea has enormous thermal inertia and lags the air by roughly two months, so it is at its coldest in late winter and its warmest at the end of summer rather than in midsummer.

That makes August, September and into October the sweet spot if the swim is a priority: the ocean has had a whole summer to absorb heat and is at its most comfortable. Winter is still swimmable for most people without a wetsuit, sitting in the high teens, but it is a brisker proposition and more people stay on deck.

The dry season is longer than you expect

The rainfall record is striking. April, May and June each record six millimetres on average, and July records none at all. That is not a dry-ish spring; that is essentially no rain for four months. August is barely different at four millimetres.

The wet end of the year is the winter, and even then it is modest by northern European standards: February is the wettest month at eighty-six millimetres over six wet days, with October and March the next. Worth noting that this is Funchal specifically, on the sheltered south coast. Madeira's north is a considerably wetter island, which is why the laurel forest grows there and not here.

Swell, wind and the state of the sea

Rainfall is not really the thing to plan around on a boat; the sea state is. Summer is generally the settled season, with lighter winds and a calmer ocean, which makes for easier wildlife watching and a more pleasant swim stop. Winter brings bigger Atlantic swells generated by systems far to the north, and the occasional day when a small boat does not go out.

This matters less on a catamaran than it would on a monohull, because the twin hulls handle swell so much better. But it is the reason a trip can be cancelled, and if you are travelling in winter it is worth booking early in your stay so there is room to rebook if a day is called off.

Wildlife across the year

The headline is reassuring: the dolphins most people see here are resident rather than migratory. Bottlenose and common dolphins live in these waters year round, which means there is no closed season for the main attraction and no month where you are simply out of luck.

The whales are a different matter and more seasonal in the sense that the pattern of species passing through shifts across the year, with the warmer months generally producing more variety. Anyone specifically hoping for a whale rather than a dolphin should lean toward summer and early autumn, and should still treat any sighting as the bonus it is.

Crowds and how busy it feels

Madeira's peak is the European summer plus the two ends of the year, since the island has a long tradition of Christmas and New Year visitors and its New Year fireworks draw people specifically. Those are the periods when boats fill up and booking ahead matters.

The quieter stretches are the shoulders: late autumn outside the festive run, and the spring weeks either side of Easter. Those are attractive if you want the smaller end of an already small group, and the weather in those months is essentially the same as either side of them.

So which month

If the swim is the point of the trip for you, come between August and October, when the Atlantic is at its warmest and the sea is generally settled. If you want the driest, brightest weather with clear air and dependable conditions, April through July is the run to aim for, and June and July are effectively rainless.

If you are already coming for other reasons, the honest answer is to book whichever day suits your itinerary. The cruise runs year round, the dolphins are resident, and the difference between the best month and the worst is far smaller here than the difference between a good day and a bad one in any given week.

One caveat on all of the figures above: they come from the Funchal station less than six kilometres from the marina, averaged over the thirty years from 1991 to 2020. That is about as local as climate data gets, and it describes the south coast well. It is a description of a typical month rather than a forecast for a particular afternoon, and Madeira's weather is famously local: the north of the island can be under cloud while Funchal sits in full sun.
