While Third Avenue lacks the plush park amenities of Coyote Point, the Bay Trail winds through the area - great for walking, biking, and rollerblading. The Third Avenue windsurfing access was created through the persistent efforts of the SFBA - the San Francisco Boardsailing Association. In 2004 SFBA funded the addition of a rinse station which is particularly appreciated after low-tide sessions.

Third Avenue's greatest charm is on the water: strong wind, big swell, open waters, great ramps, and long wild rides. The lack of obstructions near shore give Third Avenue strong steady winds fairly close to shore. The long fetch, shallow sand bars, and favorable currents make for spectacular swell in the 2-5 foot range. On epic NW-wind ebb-tide days, 6-8 foot swells roll through the channel. This is a great place for jumping and swell riding.

The sailing area is huge and you can go for miles. However, the side-offshore winds make breakdown way outside very serious. Sail with a buddy, carry an emergency kit including a whistle, line, and a strobe -- and consider carrying a marine band VHF radio (modern ones are the size of a cell phone) if you roam far from shore.

It can be crowded near the launch area both in the water and on land. The rigging area is tiny. DO NOT RIG IN THE PARKING LOT! You launch down concrete paver ramps set into the rip-rap shore line. The bottom near the launch is soft (but not sticky) mud. If the tide is below 2.0 feet at the new launch site or 1.5 feet at the Old Third Avenue launch site (near the blue tanks) you will have problems with the mud. At tides below 2.0 feet, the four sand bars between the launch and the channel create a serious hazard. There is a bar along the edge of the channel from the channel marker towards the bridge. Another bar is about halfway from the old launch to the channel marker. There are also two bars within 400 yards of the new launch stretching upwind starting on a line between the new launch and the channel marker. All of these bars can be very dangerous at lower tides. Beginners can launch from the beach cove near the entrance of the parking area where the side onshore winds keep them out of trouble.

The season starts with strong NW clearing winds in late March or April. These occur off and on through June. During the summer, thermal winds continue well into September but gradually get weaker. In the Spring clearing wind conditions, sail sizes commonly range from 4.0 to 5.0. In the Summer thermal winds conditions, sails in the 5.0 to 6.0 are more common. In the Spring, a full suit is recommended. In the Summer, lighter weight suits will do and short sleeve suits are sometimes used on warmer days *although full suits are recommended to survive a major breakdown far out in the Bay.

Beginners can practice in the beach cove downwind since the wind is side-onshore there. In the outer waters, the wind is side-offshore and the swells are large so only intermediate and advanced sailors should cruise these waters.

Non-sailing family members can also check out the golf driving range next to the launch. No-Parking signs are enforced.

From: North Bay and northern East Bay: Go south across the Golden Gate Bridge: Take 19th Ave off ramp 1 mile past bridge. Pass through Golden Gate Park and later past San Francisco State and then merge onto Hwy. 280. After several miles take the 380 off ramp heading east. Merge with Hwy 101 heading south and pass SFO airport. Then take the 3rd Avenue off ramp and head towards the Bay. Third Avenue becomes "J Hart Clinton Drive" a few blocks east of the freeway, then turns and follows the shoreline going southeast. After the main parking for the golf driving range, turn left at the middle of the range, then right into the windsurfing parking lot. From East Bay: Go across the Bay Bridge then merge with Hwy 101 heading south and pass SFO airport. Then follow the instructions above. From north of Santa Cruz: Go north on Hwy. 1 to Half Moon Bay Go east on Hwy. 92 over the coast range and at Hwy. 280 go south. After a few miles take the Hwy. 92 off ramp going East. Continue on Hwy. 92 until you near the Bay. Before the San Mateo Bridge take Hwy. 101 north. Then take the 3rd. Ave. off ramp and follow the instructions above. From Santa Cruz: Go east on Hwy 17 then north on Hwy 280. Then east on Hwy. 92. Continue on Hwy. 92 until you near the Bay. Before the San Mateo Bridge take Hwy. 101 north then take 3rd Ave. and follow instructions above.

The sensor at this site is best for telling you if there is enough wind near shore to limp to the stronger winds outside. The Third Avenue Channel and SFO sensors give a better indication of the winds outside.
