Key West, FL Daily Water Report — August 27, 2026

Today is one of those Key West days that reminds you why you live here—or why you came. The lightweight easterly breeze at four knots, gusting only to five, is almost a non-factor, and with wave heights hovering near 0.4 meters, the water is flat enough to make almost any plan a good one. Boating takes the top score at a 9 out of 10, and kayaking isn't far behind with an 8.2. If you've got a skiff, a paddleboard, or even a canoe, the window from mid-morning through late afternoon is as close to flawless as August gets. The early morning was the calmest stretch, but honestly, conditions hold steady all day. Fishing scores a solid 7.3, driven by the solunar pattern that peaks around 11:45 a.m. to 1:45 p.m. That midday window, combined with steady barometric pressure at 1017 hPa and almost no cloud cover, lines up nicely for an offshore or backcountry session. The chlorophyll reading is elevated at 1.03 mg/m³, which the model interprets as a positive sign for bait activity, but as always, what's on the surface doesn't guarantee what's below. The wildlife score of 7.8 backs up the early and late hours for bird activity or dolphin sightings, especially around the minor solunar periods at dawn and dusk. Surfing remains a non-starter with a 4.9—those 0.38-meter swells from 114 degrees at a four-second period won't push much beyond a ankle-high ripple. Sailing is workable at 6.1, but only if you're chasing a light-air cruise; don't expect to plane. Diving didn't receive a score today, which likely means one of the input variables fell outside the model's range, but the water temperature is a balmy 32.1°C and visibility stretches over 26 kilometers above the surface. Underwater clarity is a separate question. Compared to the past several days, this is the calmest wind we've seen since the 22nd, and the boating score ties that date's high mark. Yesterday was slightly breezier and scored lower for paddling, so today is a clear upgrade for anyone wanting to get on the water without fighting a chop. Looking ahead, Friday keeps the same gentle seas but builds afternoon breezes near 12 knots, and Saturday introduces a nearly 60 percent chance of rain with similar winds. The weekend trend is toward more instability, so if you've been waiting for a perfect window, take it now. The best bet today is to be on the water by 10 a.m., soaking in a south Florida morning that feels like it was designed for exactly this.
