Weather & Adriatic Sea Sailing – Forecast Resources for Planning Your Boat Trip


Ivan S.

Sailing Croatia’s Adriatic Sea is mostly a peaceful, calm affair. But, as any captain knows, seas are fickle masters, and the weather in a semi-enclosed sea like the Adriatic can change on a dime.

Now, you can’t control the weather – I mean… you can’t, right?!? – so the next best thing you can do is stay one step in front of it through research and preparation.

Here at Yachtaris, we understand that navigating the world of weather forecasts can be tricky. So to help you chart a safe and successful course during your Adriatics boating vacation, I’m here to share the trusted resources that Croatian sailors rely on for accurate forecasts.

Let’s dive in.

Mid-Term Forecast: Fine-Tuning Your Route and Packing Smart

As your Croatian sailing trip approaches, it’s time to dial in the weather details. This helps you plan your route strategically and pack accordingly. For the most reliable mid-term forecasts, seasoned sailors (and outdoor enthusiasts!) trust mostly these sources:

Croatian Meteorological and Hydrological Service (DHMZ): This is the go-to official weather service in Croatia. Their website offers clear 7-day forecasts and easy-to-read meteograms.

Meteoblue: This Swiss company provides dependable forecasts with a user-friendly interface. Check out their 7-day and 14-day predictions. A popular choice among locals, the Norwegian state service delivers reliable forecasts comparable to Meteoblue. Check the graphs on their website to understand the rends for your location.

My Tip: While all these services are great, I find Yr’s layout and additional data most helpful for planning my sailing adventures.

Short-Term: Navigating Your Sailing Itinerary

During your vacation, precise weather updates are essential to make smart, safe decisions on the water. The Croatian Meteorological and Hydrological Service (DHMZ) remains your most reliable source. Their twice-daily Marine Forecast for Small Crafts is an absolute must for skippers. Use these forecasts to make informed decisions about leaving marinas, finding safe anchorages, and adjusting your route as needed. Updated twice daily, it provides highly accurate 12-hour forecasts, general outlooks for the following 12 hours, and essential Adriatic-specific warnings like “opasnost od neverina" (squalls). Find the forecast in Croatian, English, Italian, and German, with the Croatian version being the most comprehensive (use Google Translate if needed).

When internet access isn’t an option, your trusty VHF radio becomes your lifeline to essential weather information. Local port authorities broadcast the same Marine Forecast for Small Crafts multiple times daily as part of their Maritime Safety Information (MSI). While you can find precise schedules on the Plovput page, often the easiest approach is to simply stay tuned to VHF channel 16 – you’ll receive clear announcements directing you to the appropriate channel for the forecast in both Croatian and English.

While provides a solid foundation for understanding Adriatic weather, successful navigation often requires more precise and timely information. For instance, you might need real-time updates on the proximity of announced rain clouds or granular data on the localized impact of Bora gusts within specific channels or bays. Furthermore, predicting the danger of “neverini" – those sudden, violent squalls notorious in the Adriatic – requires specialized tools and vigilance. These unpredictable storms, particularly common in the northern Adriatic during late July and August, appear with little warning and bring intense winds and rain, posing a significant threat to sailors.

Real-time Updates

The thrill of sailing lies partly in the dynamic nature of wind and weather. Conditions can change quickly on the Adriatic, even if your day starts sunny. If the weather looks unsettled, use these tools to track the forecast before leaving a safe harbor:

  • Your go-to source for official Croatian weather data. Check out their satellite and radar images to track cloud movement and rain patterns, giving you a clear picture of how the weather will change around you. They also show lightning strikes, crucial for spotting potential storms.
  • RainAlarm and Accuweather: These offer alternative forecasts tailored to Croatia, providing a second opinion to help you make informed sailing decisions.
  • Track lightning strikes in real time. This is essential for spotting those sudden summer thunderstorms (‘neverini’) that can pop up in the Adriatic.

Granular Weather Forecast

To get granular weather forecasts for your exact sailing location, again consult They offer detailed maps showing wind gusts, average wind, cloudiness, and precipitation. While these maps provide forecasts for the next three days, focus on using this data for the next 12 hours to get the most accurate and up-to-date information.

While there are many weather apps with granular weather forcaset (used mostly by wind and kite surfers), Windy and Predictwind are popular choices for sailing in Croatia. These apps offer a convenient all-in-one view of weather information. However, it’s important to be aware of their limitations. They often rely on data purchased from local providers, and the freshest data can be expensive. Sometimes, this means the information you see on the app might not perfectly reflect the current weather conditions. Be also aware that these apps can also underestimate the wind strength. Always use to the gust reports, instead of the average wind report.

If you’re participating in a regatta or organizing a boat event, you’ll want the most precise weather forecast possible. For this, consider requesting a tailored forecast from or other reliable local sources like and These specialized services typically come with a fee.

It’s unfortunate that these specialized weather sites often have less user-friendly interfaces. A better user experience would certainly make them even more valuable resources for your sailing adventures in Croatia.

Before you set sail

In conclusion, before you set sail, I always recommend checking the official forecast on or your radio system. Then, enrich that understanding with satellite, radar, lightning reports, and wind simulations from Windy.

It’s important to remember that even the best weather models have limitations, and predicting conditions in your exact location can be tricky. As I’ve experienced, sometimes strong ‘burin’ winds can surprise you at night despite a forecast for light ‘bora’ (these localized winds are driven by temperature differences and are harder to predict).

\When in doubt, don’t hesitate to contact your base and ask for their advice based on local experience.
