TEMCO Kalama Terminal, WA Daily Water Report — August 28, 2026

Today at the TEMCO Kalama Terminal, the water beckons with a strong nod towards boating and kayaking. With a stellar boating score of 9/10 and kayaking at 8.3/10, conditions are prime for a smooth and leisurely paddle or sail. The calm waters, registering wave heights at an unflappable 0 meters, offer an ideal setting for those seeking tranquility on the water. This glassy surface is coupled with light winds averaging 6 knots from the north, though gusts may reach up to 18 knots by late evening. Fishing enthusiasts will find a decent opportunity with a score of 7.5/10, slightly improved from yesterday's 6.5/10. The full moon might add a touch of magic to the solunar periods, particularly around midday. While the surfing score remains steady at a modest 4.5/10, those looking to catch waves may want to explore other locales with more favorable surf conditions. Diving conditions are consistent with recent days, holding at a respectable 7.6/10. While the absence of wave activity is a boon for visibility, the lack of ocean surface temperature data means divers should be prepared for varying thermal conditions. The weather is supportive today with no rain in sight, a comfortable temperature range from 13.7°C to 23.8°C, and a visibility stretching to 23.5 kilometers. However, the barometric pressure is on a slight decline, which could suggest a change in weather patterns as the week progresses. Looking ahead, the forecast suggests a continuation of calm marine conditions through the next few days, with temperatures gradually climbing towards the end of August. As we move into early September, keep an eye on the increasing likelihood of rain, particularly on September 2nd, when the chance of precipitation spikes to 77%. For today, the best bet is to take advantage of the serene water conditions and enjoy a peaceful outing on the calm, inviting Columbia River.
