Split’s Wind System, In Plain Language
Maestral (NW) is the friendly summer sea breeze. It starts late morning, peaks mid afternoon, and fades near sunset. Expect 10 to 18 knots most days, sometimes more in channels. Plan crossings in the morning and swims when it’s building. That rhythm keeps days smooth.
Bura (NE) is dry and gusty. It can arrive fast after a pressure change. Gusts funnel through gaps and downslope valleys and create steep, short seas. Reduce sail early, choose lee-side harbors, and avoid long exposed fetch.
Jugo (SE) is warm and often brings cloud, rain, and swell. It builds gradually, can blow for days, and raises sea state on south-facing shores. Use marinas or protected bays and plan routes with more downwind time.
Other local winds you may hear
- Tramontana (N): a fair-weather northerly, usually moderate
- Levanat (E) / Levant: unsettled easterly, sometimes with swell
- Oštro (S): southerly that can precede fronts
These names help locals describe shifts around fronts and thermal cycles. Your skipper will factor them into the plan each evening.

Seasons at a Glance
- May–June: Long days, lighter crowds, sea warming from the high teens into low twenties Celsius. Maestral reliable most afternoons.
- July–August: Hottest months. Sea often 24–26 C. Afternoons bring a stronger maestral and more traffic near Hvar and Brač.
- September–early October: Warm sea, softer crowds, stable windows. Many skippers call September the sweet spot.
Note that recent years have seen warmer seas during some weeks, driven by wider Mediterranean heat anomalies. Expect variability year to year.
Sea and Air Temperatures
- Sea: coolest in Feb around ~13–14 C; warmest in Aug around ~24–25 C.
- Air (Split town): average highs peak in July; the cool season runs roughly late Nov to mid Mar. Pack a light layer even in summer for night breezes.
How to Plan Your Day Around the Wind
- 08:00–10:00 Weather brief and route check. Confirm marina or mooring options.
- 09:30–12:30 Longer legs while seas are flatter and winds lighter.
- 12:30–14:00 Swim-stop and lunch as the maestral builds.
- 14:00–16:30 Short hop to a protected bay or marina. Expect the day’s peak breeze now.
- 17:00–20:00 Wind eases near sunset. Go ashore for dinner or enjoy a calm cockpit.
That timing mirrors Split’s thermal cycle and reduces fatigue for the helmsman and crew.

Sea State and Local Geography
The Split Channel between Brač and Šolta can accelerate the afternoon breeze. Expect a touch more chop there when the maestral peaks. South-facing anchorages feel a Jugo swell first. On Bora days, harbors with northern exposure are less comfortable. Choose marinas or coves with hills to windward.
Rain, Thunder, and Visibility
Summer turns are sunny overall, but brief storms can pop up, especially with a front or before a Jugo period. Visibility is usually very good. When showers move through, wait for radar echoes to pass and reassess fetch and gusts before departing.
Best Months to Sail Split
- Calm and warm: June and September deliver warm water and reliable wind with fewer crowds.
- High energy: July and August bring livelier afternoons and busy town quays. Book berths and tables early.
- Budget-friendly: May and early October offer value with cooler nights and a kinder pace.

- Favor ACI Palmižana for Hvar nights when a late maestral is likely.
- When Jugo builds, choose marinas with better lee and shorter fetch.
- On a Bora alert, avoid long exposed legs and keep a second plan ready.
