• Frederikssund mod nord tær drivis, mellem 5 og 10 cm tyk, kvadderis. Sejlads vanskelig eller farlig for træskibe uden isforhudring.
• Frederikssund havnen fastis, mellem 5 og 10 cm tyk, kvadderis. Sejlads vanskelig eller farlig for træskibe uden isforhudring.
• Karrebæksminde havnen tæt drivis, mindre end 5 cm tyk, kompakt kvadderis. Skibsfart uhindret.

Bornholm:

• Isfrit.

Med hensyn til havisen i de danske farvandene:

• Temperaturen kommer alt tættere på frysepunktet i Smålandsfarvende og på nordsiden om Lillebælt. Det begynder at fryse på nord om Lolland i Smålandsfarvandene. Under de kommende to dage vil isen udvide sig mod nord, samt fra sydvestkysten av Sjælland. Områder med 0.1-0.2 meter tyk is kan forekomme. Det vurderes at der ikke vil dannes havis i sejlrute nord om Fyn under de kommende dage. Ellers er der allerede is i Roskilde fjord og Isefjord, som vil blive alt tykkere og dække næsten hele fjorden under de kommende dage.
• Overfladetemperaturen i de andre åbne farvande er over 1.0 grader og det vurderes at der ikke vil dannes is i disse områder. På længere sigt (2-5 dage) bliver det alt mere koldt og is kan dannes ved kysten rundt om Sjælland, Fyn Lolland og Falster. Muligvis kan det vokse ud mod farvandene, med størst risiko for vestlige Østersøen.

With regard to sea ice in Danish waters:

• The temperature is getting ever closer to the freezing point in Smålandfarvende and on the north side around the Little Belt. It is starting to freeze north of Lolland in Småland's waters. During the next two days, the ice will expand to the north, as well as from the south-west coast of Zealand. Areas with 0.1-0.2-meter-thick ice may occur. It is estimated that sea ice will not form in the sailing route north of Funen during the coming days. Otherwise, there is already ice in Roskilde fjord and Isefjord, which will get thicker and cover almost the entire fjord during the coming days. 
• The surface temperature in the other open waters is above 1.0 degrees and it is estimated that no ice will form in these areas. In the longer term (2-5 days) it will get colder and ice can form on the coast around Zealand, Fyn Lolland and Falster. Possibly it can grow towards the waters, with the greatest risk for the western Baltic Sea.
