Cape Cod, MA Daily Water Report — August 22, 2026

Today’s conditions around Cape Cod are shaping up nicely for divers, with an outstanding suitability score of 8.8 out of 10. The water's calm demeanor and decent clarity make it a prime day to explore beneath the surface. Boaters and kayakers can also expect a pleasant outing, with scores of 7.5 and 6.6, respectively, thanks to gentle winds peaking at a manageable 9.4 knots and wave heights staying between 0.3 to 0.6 meters. Fishing enthusiasts can look forward to a solid day on the water, scoring 6.3/10. Key periods to cast your line would be during the solunar major from 15:52 to 17:52, when fish activity is expected to peak. The waxing gibbous moon should provide a bit of celestial encouragement, although the high chlorophyll levels won’t guarantee fish activity. Surfers might find themselves on the lower end of the thrill scale today, with a score of 4.8/10. The relatively small swell from the east (93 degrees) and shorter wave periods mean the rides might be brief and less exhilarating. However, with the calmest waves arriving around 11 PM, night surfers could enjoy smoother conditions if they’re up for a late session under the moonlight. Keep an eye on the barometer, which is currently sitting at 1015 hPa and falling, suggesting a potential shift in weather patterns. Looking ahead, the next few days promise a warming trend with temperatures climbing to a high of 26.8°C by the 28th, though there’s a slight chance of rain creeping in on the 23rd and again at the end of the week. For the best experience today, grab your diving gear and head out while the waters stay calm and inviting.
