Best Time for a Boat Tour to Favignana & Levanzo: Sea Temperature, Crowds & Season

Why the boat tour season is shorter than Favignana’s tourist season

The island itself sees visitors from April through October — walkers, cyclists, day-trippers off the ferry — but the boats that reach Cala Rossa, Bue Marino and Levanzo’s coves are small open or semi-open vessels, and running them in a choppy winter sea off western Sicily is neither comfortable nor, for most operators, worth doing. That is why the window that matters for this site is narrower than “when is Favignana nice”: it is when the fleet is actually sailing.

One Egadi operator’s own published guidance for visitors puts it plainly: the best time to visit is between May and October, with June, July and September singled out as the months with the best mix of weather and fewer crowds than peak August. That matches what shows up in this site’s own 52-tour dataset — the overwhelming majority of listings are for a June-to-September full-day itinerary, with a smaller shoulder-season set in May and October and almost nothing bookable in winter.

Sea temperature: the number that actually decides your trip

For a boat day built around swimming and snorkelling, sea temperature matters more than air temperature. The water off Trapani and the Egadi Islands is coldest in February, at around 14°C, and warmest in August, at around 26°C. It crosses the comfortable-swimming threshold of roughly 20°C in June and stays above it into November, though by then only a handful of the site’s 52 tours are still running to take advantage of it.

Rain, wind and daylight

Rain is rarely a reason to pick one month over another here in season: July is essentially dry, and June, August and early September see very little either. The wetter months — November through February — are also the months almost nothing sails, so the two facts barely interact in practice.

Wind is the more useful thing to watch. Western Sicily and the channel between Trapani and the Egadi Islands see two prevailing winds, the Maestrale from the northwest and the Libeccio from the southwest, and the windiest month on average is January — already outside the season. Inside the season, summer afternoons can still build a stronger breeze than the morning had, which is one reason most full-day tours front-load their swim stops earlier rather than later in the day. A choppy forecast is a reason to ask your operator about the day’s planned route, not a reason to change your month.

Daylight is a smaller factor on a single-day trip, since most tours run within a broadly similar morning-to-evening window regardless of season, but it does set how much of the day is usable. Mid-June gives close to 14 hours 47 minutes of daylight at this latitude; by mid-October that is down to roughly 11 hours 16 minutes, which is part of why October’s remaining tours tend to run a shorter, simpler route.

Crowds and prices, month by month

June, July and September are when the fleet runs at full strength and prices sit at their normal range. August is different: it is Italy’s own peak holiday month as well as the international one, and the week around Ferragosto (15 August) is the single busiest and most expensive stretch of the year on this route — the best-known coves on both Favignana and Levanzo are at their fullest, and the small-group and private boats sell out furthest in advance.

May and the second half of September into October are the deliberate alternative for anyone who would rather trade a few degrees of sea temperature for a quieter boat and an easier booking. Fewer tours run in those windows, so the trade is real: check what is actually operating on your date before assuming the same choice of small-group boats will be available. Our Favignana boat tour prices guide covers what the same tour typically costs across the season.

So, when should you actually go?

If you want the best overall balance: June, July or the first half of September. The sea is warm enough to enjoy fully, the whole fleet is running, and outside the first three weeks of August you are not fighting the year’s biggest crowds.

If warm water and a lively island matter more than crowds or price to you: August. Accept that it is also the most expensive and most crowded month, and book your boat well ahead — this is when small-group tours sell out first.

If you would rather have a quieter, cheaper trip and don’t mind a cooler sea: May, or late September into October. Confirm your chosen operator is actually sailing on your date, since the timetable thins out fast at both ends of the season.

If your dates are already fixed and fall outside May–October: the boat excursions themselves are very unlikely to be running. The island, the ferry and the town are still worth a visit, but this is not the trip to build around swimming at Cala Rossa or crossing to Levanzo. Check our Favignana boat tour prices guide and group boat tours guide once you have picked a month, and check live availability and prices for your exact dates — that is the only way to see which tours are actually bookable on a given day this far out.

Frequently Asked Questions

What is the best month to visit Favignana by boat?

June, July and the first half of September give the best overall balance of warm sea, a full boat-tour timetable and manageable crowds. August has the warmest water but is also the busiest and most expensive month.

Do Favignana boat tours run in winter?

Essentially no. The season runs roughly late April/May through October, and from November to March the great majority of listings show no availability. The ferry to Favignana still runs year-round.

Is it too cold to swim in May or October?

Not for most people. Sea temperature is around 18–19°C in May and around 21°C in October — brisk but swimmable, cooler than the June–September peak of 23–26°C.

When is Favignana the most crowded?

The week around Ferragosto (15 August) is the busiest and most expensive stretch of the year, at the best-known coves and on the small-group boats in particular.

Is wind a problem for boat tours?

Rarely inside the season. Western Sicily’s prevailing winds, the Maestrale and Libeccio, are strongest in winter, when almost nothing sails anyway. In summer, afternoons can be breezier than mornings, which is why most operators run swim stops earlier in the day.

Should I book in advance for August?

Yes. August is the year’s peak month on this route, and small-group and private boats are the first to sell out, often weeks ahead.

How we know

Sea and air temperature figures are averaged from publicly published Sicily/Trapani climate data (climatestotravel.com, en.climate-data.org and seatemperature aggregators), cross-checked against an ERA5 reanalysis computed for Favignana’s coordinates (Open-Meteo, 1991–2020) for the ranking of driest, wettest and warmest months — we did not have direct access to ARPA Sicilia’s own station bulletins for this build, so treat the exact degrees as indicative rather than official normals. Daylight hours are computed directly for Favignana’s latitude and are exact. Wind pattern information comes from Windfinder’s published Trapani wind statistics. The boat-tour season and best-months guidance is cross-checked against an Egadi Islands tour operator’s own published visitor FAQ and against the actual month-by-month spread of the 52 tours in this site’s own offers data. Prices and reviews throughout the site are refreshed from GetYourGuide’s own listings, not from this page. What these numbers cannot tell you is what your own date will actually bring: they are long-run averages, not a forecast, and they say nothing about a single day’s wind, swell or cancellation risk — for that, check the forecast closer to your trip and confirm with your chosen operator’s own current listing before booking.
