Swell: 2–3 ft
Temp: 69–71°F

High tide: ~1:29 pm
Low tide: ~7:12 pm

Conditions are holding fairly steady around SD. Visibility is averaging around 10–15 ft, with hazy, green water still lingering at many spots. Areas that are more sheltered from the swell are offering the best visibility.

Expect moderate swell and light southwest winds throughout the day, making for generally manageable surface conditions.

Looking ahead, the first signs of the incoming hurricane swell will begin to show this weekend. Most of the impact is expected later Sunday into Monday, when south-facing breaks will see the largest increase in surf, with waves building into the 2–4 feet overhead range.

Diveable conditions continue today, but expect some green haze in the water. If you're looking for the best visibility, stick to the more protected sites. Keep an eye on the forecast if you're planning to dive later this weekend, as the incoming south swell is expected to become more noticeable by Sunday afternoon and into Monday.
