Meteorology

- On 12 August 2026, a partial solar eclipse in Germany, with up to 90 per cent coverage, will coincide with the peak of the Perseids.
- Despite its red colour, the Sun must only be viewed directly through certified ISO 12312-2 solar eclipse glasses; improvised solutions are unsafe.
- The best time to observe the Perseids is after midnight until dawn, when there is no moonlight; weather conditions are expected to be particularly favourable inland and in parts of the Baltic Sea region.

​Solar eclipse and the Perseids in 2026: Stay awake on the night of nights!

- The 2026 Perseid meteor shower will peak on the night of the new moon, 12–13 August; under ideal conditions, up to 100 meteors per hour may be visible.  
- Particularly good viewing opportunities for sailors in dark bays and regions such as Spiekeroog, Pellworm, Westhavelland, Møn/Nyord and Anholt.  
- Explanations of the origin and name of the Perseids, photography tips for cameras and smartphones, and cultural customs relating to making wishes on shooting stars.

- On 12 August 2026, a rare and significant solar eclipse will take place; it will be total in northern Spain and the Balearic Islands, and partial (up to 90 per cent) in northern Europe.  
- For sailors, an unobstructed view to the west-north-west and keeping a safe distance from coastal hills are crucial; totality will be visible off the coasts of Valencia, Mallorca and Ibiza, amongst other places.  
- It is essential to use ISO-certified eclipse glasses; the DLR is studying the ionosphere; minor GPS disruptions and short-term weather effects are possible, but pose no particular danger.

- Alpine lakes are very popular in hot weather, but can become dangerous within minutes due to rapidly developing thunderstorms and Föhn gales.  
- A two-tier storm warning service using orange lightning symbols (40/min for strong winds, 90/min for storms) warns of dangerous gusts on Lake Constance and the Bavarian lakes.  
- Switzerland and Austria use similar visual warning systems, some with two warning levels and others with just one, depending on the lake or federal state in question.

- A 65-year-old woman fell overboard during a storm on Lake Constance and was recovered dead the following day off Langenargen.  
- Around 200 emergency personnel from Germany, Austria and Switzerland searched for the missing woman; the search was suspended in the evening.  
- The Lake Constance warning system, featuring orange storm lights and advice on what to do, is designed to protect people from rapidly approaching thunderstorms and strong winds.

- In the Croatian Adriatic, the Bora, the Jugo and, in particular, the highly unpredictable Nevera pose significant dangers to charter crews.  
- The Bora is a cold, gusty downwind with gusts that can reach gale force, whilst the Jugo is a steady south to south-easterly wind that builds up the swell.  
- Nevera are short, violent thunderstorms with gale-force gusts; DHMZ and lightning detection apps are key tools for assessing the risk.

- Böen entstehen durch dynamische (Reibung, Topografie, Höhenwinde) und thermische Turbulenz (labil geschichtete, aufsteigende Warmluft).
- Kaltfronten, Trogtiefs, labil geschichtete Herbstlagen und ablandige Winde an gegliederten Küsten führen zu besonders heftigen, drehenden Böen.
- Warnsignale sind Quellwolken, Schauer-/Gewitterlinien, verdunkelte Wasserflächen und Schaumkronen; Skipper müssen schnell Kurs und Segel anpassen.

- Über dem Bodensee bei Friedrichshafen bildete sich eine bis zu 20 Minuten sichtbare Wasserhose mit geschätzten 100–150 km/h Windgeschwindigkeit.
- Trotz Nähe zum Ufer, Angst unter Beobachtern und zahlreicher Fotos/Videos gab es laut Wasserschutzpolizei keine Notfälle oder gemeldeten Schäden.
- Auslöser war eine Gewitterzelle über ungewöhnlich warmem Wasser; Wasserhosen sind selten, meist kurzlebig und am Bodensee typischerweise im Spätsommer.

- A stable high-pressure system, intensified by climate change, is bringing heat, calm conditions and a light sea breeze, particularly on the outer regatta courses.
- Temperatures of over 30 degrees and an increased risk of thunderstorms are expected until the final weekend, followed by a change in the weather with westerly winds and greater influence from low-pressure systems.
- In the long term, hot days, dry spells and light winds are becoming more frequent during Kiel Week, whilst the traditional ‘14 degrees and drizzle’ weather is becoming less common.

- A stationary high-pressure system over the North Sea and the Baltic Sea is initially bringing heat, sunshine, calm conditions and light swells, which in some cases is testing the patience of sailors.  
- From Friday, according to the DWD, there will be a regionally increasing risk of thunderstorms, some of which may be severe, accompanied by gusts, heavy rain, hail and sudden strong winds such as downbursts.  
- Crews should factor in engine hours and heat precautions, closely monitor weather models and DWD warnings, and opt for shorter legs with a safe harbour.

- In the 19th century, Georg von Neumayer studied ocean currents using messages in bottles and used his findings to create a groundbreaking current map.
- His approach continues to have an impact: since 2000, Argo floats have been measuring ocean temperature, salinity and pressure worldwide, supporting climate prediction models.
- Neumayer founded the German Maritime Meteorological Service, shaped its development until 1903, and was a pioneer of polar research; the Neumayer Antarctic Station is named in his honour.

- Reefing early, starting the engine, and securing the vessel’s position, the crew and the electronics significantly reduces damage during thunderstorms at sea.  
- Thunderstorms at sea are difficult to predict; frontal thunderstorms bring squalls, heavy rain, sudden changes in wind direction and strong, gusty winds.  
- Effective lightning protection requires continuous earthing of the rig and metal parts, equipotential bonding and protection of electronic equipment against induction damage.
