Reykjavik, Iceland Daily Water Report — August 25, 2026

Today in Reykjavik's harbor, it's a prime day for boating and sailing. With a boating score of 7.5 and sailing at 7.6, the conditions are favorable thanks to moderate winds from the WSW, peaking at 16.9 knots, and a manageable wave height of 0.58 meters. The sea surface temperature is a brisk 10.7°C—slightly cooler than average—so pack an extra layer if you're heading out. For fishermen, the score has improved to a 6, up from yesterday's 5.2, suggesting a slightly better bite, possibly influenced by the high chlorophyll levels indicating potential baitfish activity. However, with no tide data available and a waxing gibbous moon, you'll want to align your efforts with the solunar periods for the best results. Diving conditions are also looking up with a score of 7.4. The relatively calm seas and clear skies should provide decent visibility, but remember, the water is chilly, so a good wetsuit is essential. Surfers, on the other hand, might find today less thrilling with a score of 5.8, as the wave period doesn't quite deliver the punch for an exhilarating ride. Looking ahead, the rest of the week sees a mix of conditions. Tomorrow, wind speeds decrease slightly, and wave heights are expected to increase, offering a bit more challenge for sailors and surfers. The trend towards calmer seas continues through the weekend, with wave heights dropping to a gentle 0.3 meters by Sunday, making it an ideal time for kayaking enthusiasts to hit the water. All in all, if you're seeking the best window today, set sail or motor out early to catch the calmest seas around 6 AM.
