SSI Waves, Tides & Currents
The site was calm yesterday. Today the same spot has a current pulling sideways that nobody mentioned at the dive briefing.
Coastal conditions change by the hour, and most divers never learn to read them before getting in the water. SSI Waves, Tides & Currents teaches you to recognize what is actually happening at a site, including real drift diving technique that turns current from a hazard into one of the most exhilarating ways to dive.

Coastal Conditions Change by the Hour. Most Divers Never Learn to Read Them Before They're in the Water.
Coastal diving is shaped by forces most divers never learn to read: wave formation, tidal cycles, and current patterns that can turn a familiar site into something unrecognizable in a matter of hours. Without that knowledge, you are relying entirely on the dive guide to notice what changed.
SSI Waves, Tides & Currents teaches you to understand and plan around all three, including dedicated technique for drift diving, the difference between fighting a current and using it. $249 per diver (group) or $349 (private). Prerequisites: Open Water Diver, minimum age 10.
Most Open Water Training Happens in Calm Conditions. Real Coastal Diving Often Is Not.
If you have only dived calm lakes or sheltered sites so far, ocean conditions involving real current, tide, and wave action are genuinely a different environment, not a more advanced version of what you already know. That gap is exactly what this course is built to close.
This is exactly what continuing education is for. Not to prove you are advanced. To replace uncertainty about ocean conditions with the ability to read them and plan around them confidently.
This Course Is for the Diver Heading Into Real Coastal Conditions
This is usually the right next step if any of these sound familiar.
You are planning a coastal or ocean dive trip
Understand the conditions you will actually encounter before you are standing on the boat trying to figure it out.
You've heard about drift diving and want to try it
Properly taught, drift diving is one of the most exhilarating and effortless ways to dive. This course teaches the technique.
You want to recognize hazardous conditions before entering the water
Reading wave and current conditions from the surface is a real, learnable skill that improves every coastal dive.
You are heading toward more demanding diving environments
Understanding water movement is foundational for several Access-lane specialties ahead.
Choose Your Optimize-Lane Course
You want to read ocean conditions confidently
Best for coastal diving, drift technique, and recognizing hazardous water conditions.
You want the full charter and liveaboard logistics
Best for the broader procedures of diving from a boat, which often pairs with this course.
You want general orientation skills first
Best for compass and natural navigation fundamentals before adding current and tide complexity.
What This Course Actually Covers
"Current diving is always dangerous."
Current diving requires specific technique and awareness, both of which this course teaches directly. Properly executed drift dives are popular precisely because they are exhilarating, not because they are reckless.
"This is only relevant for ocean diving, not local lakes."
While the course focuses on coastal and ocean dynamics, reading water movement and planning around conditions applies to any open water environment, including Austin-area lakes in windy conditions.
"I need advanced experience to take this."
Open Water certification is the only prerequisite. This course is designed for any certified diver planning coastal or ocean travel.
"This is the same as Boat Diving."
Boat Diving covers the logistics of diving from a boat. This course focuses specifically on reading and diving in wave, tide, and current conditions, which can apply to shore diving too.
What You’ll Train
A fully academic course covering wave, tide, and current dynamics, including drift diving technique.
Build foundational understanding of how different coastal environments behave under varying conditions.
Learn the physics of wave formation and how to read surf zone dynamics from the surface before entering the water.
A dedicated academic session on drift diving: positioning, buddy contact, and surface signaling for safe, enjoyable current diving.
Apply everything to real dive planning, building the judgment to recognize and respond to changing conditions.

Frequently Asked Questions
Properly executed, drift diving is a safe and popular form of diving. The specific risks are well understood and directly addressed by this course's training in positioning and buddy procedures.
The core skills of reading water movement and planning around conditions apply broadly, though the course focuses primarily on coastal and ocean dynamics most relevant to travel diving.
Many divers take both, since coastal trips often involve boat diving in current. They complement each other well but are not required together.
No. This is a fully academic course with online study via the MySSI app.
No in-water component means no medical screening is required for this course specifically.
