Chatham, MA Daily Water Report — August 30, 2026

Today in Chatham, the water conditions are looking quite favorable for those keen on diving and boating. If you're a diver, you're in luck with a stellar score of 8.8 out of 10, thanks to relatively calm seas and decent water temperatures at 20.3°C. Boaters will enjoy a solid 7.9, with wind speeds mostly manageable at around 5 knots from the WSW, although gusts could reach up to 23.7 knots by nightfall. Fishing enthusiasts will find the day decent, scoring 7.3 out of 10. The solunar major periods in the early afternoon, combined with a high tide at 14:06, should create some productive windows. The pressure is slightly falling, so keep an eye on that if you're casting lines. Wildlife watchers can expect a good day as well, with a score of 7.6, thanks to favorable solunar timings and wind conditions. Surfers, however, might find the waves a bit underwhelming today, with a score of 4.9. The modest 0.42-meter waves at a 4.4-second period won't provide much thrill. Kayakers get a moderate 6.1, but should be cautious of the increasing wind gusts later in the day. Comparing to recent days, diving remains consistently excellent, while boating has seen a slight improvement. Fishing holds steady, but surfing has dipped from earlier in the week when scores were in the 6s. Looking ahead, the next few days will bring slightly cooler temperatures and a chance of rain, especially as we move into September. Winds are predicted to pick up towards the weekend, with wave heights increasing to nearly a meter by September 5. For today, your best bet is to dive into the calm waters and enjoy the clarity and warmth before the winds pick up.
