# Mykonos and Delos by boat: a day facing the Meltemi

> Delos is close to Mykonos, but proximity removes neither Meltemi nor archaeological-site rules. Fix the access time, keep Rhenia flexible and abandon the programme when the passage exceeds the crew.

- Departure : Tourlos, Mykonos or Ornos
- Indicative distance : 15 to 30 NM depending on the loop
- Time under way : 2.5 to 4.5 hours under way
- Season : May to October, frequent summer Meltemi
- Exposure : Funnelled Meltemi and short seas between islands

## A short loop with real decision points

From Ornos, reach Delos for the authorised time, choose one Rhenia bay and return directly.

### Observe the channel from Ornos

Visible gusts and chop outside give a more useful signal than the distance display.

### Reach Delos with access confirmed

Landing, times and approaches are controlled. The boat needs a clear waiting or departure plan.

### Use Rhenia as the flexible stop

Several bays exist, but shelter changes with wind and traffic. One is enough.

### Return before Meltemi builds

Do not rely on a speed the boat cannot comfortably hold in short seas. Leaving early preserves course choice.

## Meltemi turns miles into time

A moderate wind increase can materially reduce comfortable speed and add spray or fatigue. Lee effects below islands are irregular.

Delos is protected and controlled. Official times and rules belong in the route as hard constraints.

## Check before departure

- Confirm Delos access time and procedure.
- Read gusts and waves in the Mykonos–Delos channel.
- Select one Rhenia bay and an alternative.
- Prepare a Mykonos-only plan.

## Practical questions

### Can Delos be reached without a skipper?

That depends on boat, qualifications, local experience and conditions. Short distance does not offset Meltemi beyond the crew’s ability.

### Do Delos and Rhenia fit in one day?

Yes with confirmed Delos access and one Rhenia stop. That final stop must remain easy to remove.

### When is Meltemi most disruptive?

It is frequent in summer and may build by day, but only a current local marine forecast supports planning.

Distances and times are planning ranges. Check official charts, notices to mariners, local rules and a current marine forecast. The skipper remains responsible for every decision.
