What changed this week
Daytime highs stay steady near 29°C all week, with only Wednesday dipping to around 28°C, so temperature is not the variable to watch. The change is in the sea state: conditions build from moderate early in the week to an elevated sea state on Friday, then stay unsettled through the weekend, with thunderstorms possible on Sunday.
Who this affects
Sea conditions matter most if your journey includes a boat leg. Smaller craft are the first to be affected — Friday is noted as unsafe for small boats — while larger vessels are generally more tolerant of choppy water. Road-based travel by bus, minivan or private transfer is not affected by sea state, though heavy rain can slow journeys.
Practical impact for travellers
- Allow buffer time between connections; rough seas can delay departures.
- If you are prone to seasickness, favour the calmer early-week days over Friday and the weekend.
- Keep bags and electronics in waterproof covers on open-deck sections.
- Check the cancellation and change terms shown at booking before you pay.
- Confirm departure times with your operator on the morning of travel.
