Meteorology

- El Niño will dampen hurricane activity in the Atlantic in 2026, while the most active typhoon season in a decade threatens in the Northwest Pacific.  
- Caribbean sailors will benefit statistically from fewer storms, but will still have to observe hurricane belts, safe harbours and strict insurance requirements.  
- Pacific sailors and yachts remain bound to restrictive cyclone zones despite a calm forecast; only minor El Niño effects are expected for the North and Baltic Seas.

El Niño expected: calmer Atlantic, extremely stormy Pacific

- Advection fog occurs when warm, humid air passes over colder water; it can persist for days and often ends with a cold front and wind shift.  
- Radiation fog forms on clear, windless nights over land, flows down to the sea in depressions and dissipates in the morning as it warms up.  
- Frontal fog occurs during warm fronts, when stratus clouds reach the water surface, and disappears shortly after the front passes, provided no advection fog follows.

Safety: Three types of fog - how they appear and disappear again

- Distinguish between fog types: Radiation fog is usually short-lived, advection fog longer; if visibility is <1,000 m, it is better to stay in harbour.
- In the event of sudden poor visibility: reduce speed, set radar reflector, use lights and sound signals, secure and involve the entire crew.
- Use radar, plotter and echo sounder in a targeted manner, avoid large vessels, anchor outside the fairway if necessary and monitor traffic by radar and radio.

Safety: visibility gone! How to keep a clear view even in fog

- High-quality, sometimes high-resolution weather and routing apps with special models for certain areas are essential for safe cruise planning.  
- The 15 apps presented cover a range from free services to complex professional solutions with routing, satellite connection and plotter functions.  
- Price and subscription models vary greatly; users have to choose between one-off purchases, annual subscriptions and regionally limited packages depending on their needs and budget.

Apps for sailing: The best weather apps for the 2026 season

- 20 selected apps cover weather, navigation, on-board instruments, safety, anchoring and trip planning for sailors in 2026.  
- Many applications offer powerful functions, but sometimes require complex set-up, ongoing subscriptions and incur additional costs for nautical charts.  
- Offline functionality, connectivity to on-board hardware and direct emergency call and alarm functions are key criteria for selecting apps on board.

- Despite an 80 % probability, there was no major saltwater inflow in 2026; there was only a weak to moderate inflow via the Öresund.  
- Oxygen deficiency in deep basins (>70 m) and nearshore oxygen deficiency are separate phenomena and are not directly related.  
- The oxygen-depleted areas have been stable since the 1970s, but the oxygen depletion rate has almost doubled in 30 years due to nutrient inputs.

Breathlessness under the keel: Why the Baltic Sea is running out of air at depth

- Extreme waves accumulate in the Mediterranean, most recently almost 13 metres off Menorca and 16.6 metres during cyclone "Harry" between Sicily and Malta.  
- This is caused by long-lasting storms over unusually warm water; climate change increases the frequency and intensity of such events.  
- Satellite and buoy measurements improve cruise planning, but small-scale extreme events remain difficult to predict; experts advise increased caution.

Mediterranean: Monster waves off the Balearic Islands again

- Kirsten Harmstorf-Schönwitz reports in the sailing podcast about preparation and experiences with heavy weather sailing at sea.  
- She describes critical situations such as a grounding off Helsinki and the 2019 Fastnet Race with gusts of up to 120 knots.  
- Key topics include safety training, precise communication on board and prevention to prepare crews for heavy weather.
