Open Water Swims

These are all the swims for the 2019 open water season for Pacific Masters Swimming.

Last Update 09/14/19

This page will be updated if a venue changes or a race is cancelled due to the water level or quality.

This year the magic number is 6. Your top 6 finishes count toward the 2019 open water points competition. Only open water swims longer than 500 meters will be considered for points.  Remember, if swims are cancelled or added then that number could be adjusted.

The results of each open water race will be posted on the open water results page.

The Open Water Points competition has two divisions for the two different types of suits. Here is the link to the rule: swim suit rules. Please review them before leaving for the open water swim. Please also note that no tape (spider tapes, bandages, duct tape, etc…) is allowed in either category.


  • Age Group determination: You will swim in the age group determined by your age as of December 31, 2019.
  • Swim Suits: Category 1 Long suits are allowed for both men and women in Open Water but can not contain clasps or zippers.  The swimsuit shall not cover the neck and shall not extend past the shoulder nor below the ankles. USMS Rule 303.7.2

Only Open Water Points scored with Category One suits will count toward Swimmer of the Year.  For more details on the rules governing open water points see here.

Awards: Swimmers will receive special awards based on their place in their gender, age group, and category of their suit (1 or 2.) Typically 1st through 3rd places receive awards, but this can change. However, to be eligible for an award a swimmer must swim the minimum number of events (3) in their category. Swimmers who have yet to swim the minimum number of events will show their place in light red.

The 2019 Del Valle Open Festival, nestled in the Livermore Valley Wine country, begins on Saturday with a 5K/10K. The swims run at the same time. You have to pre-register for the 10K.  On Sunday, the 1.2K and the 2.5K will be held. There is clear cutoff times in the event info for all races.  If you’re new to open water swimming, try the 1.2K swim or the Just for Fun Division.

Santa Cruz Open Water Weekend

Saturday, August 3: 45th Annual Roughwater 1 mile Swim
Sunday, August 4:  The Cruz Cruise 2 mile Swim

The Saturday 1 mile ocean swim goes around the Santa Cruz pier. The Sunday 2 mile ocean swim goes around the same pier, loops around the other side and comes back. The water is usually 58-61 degrees! Both are fun and very popular swims even if you’re numb. The Saturday swim is one of the bigger events and is started in two waves: under 40 years old and 40 years old and over. The Sunday swim is smaller and very low key; it is NOT for novice swimmers. 

For both swims bring lots of quarters for the street parking meters ($1.00/hour). Or walk a long way. You may want to bring a chair if you don’t like sitting on a sandy beach. On Saturday there is no post event food, but there are plenty of restaurants right there. On Sunday there will be plenty of warm beverages and snacks at the finish.

The Saturday swim starts at 11am and often the fog has lifted by then. The Sunday swim starts at 8:30am and is usually foggy. (Since the water is +/- 60 degrees it's important to stay warm: wear a thermal cap and ear plugs and don’t stop to look around while you are out there. Keep moving and have fun!

Saturday, August 10
38th Annual Donner Lake Open Water Swim
2.7 miles (SNM)

This race was cancelled for safety concerns.

The number of races that count towards the

open water competition is still six.

One of the longest swims of the season. The start is at the east end of the lake at 8:30am and the finish is at the west end. If you drive along the shore of the lake you will marvel at how far you will swim. The swim is limited to 400 swimmers this year, and is known to quickly fill its entry limit. Enter early if you wish to swim the Donner Lake Open Water Swim. Registration closed.

Free shuttle buses run between the start and the finish. Swimmers are given a plastic bag at the start to hold their sweats. It will be transported to the finish for you. 

If you are interested in purchasing any Donner Lake Open Water Swim merchandise please view the merchandise page.

Sunday, Septemeber 8
Whiskeytown Lake 
1 & 2 mile (RAD)   

The race is back!!!! Let's support this event and help with the recovery in the area. The venue will be the same as previous years, Brandy Creek Beach. 

Whiskeytown Lake is just outside Redding so plan to drive up the day before. This is a beautiful lake. There’s a nice shady picnic area and beach so bring the family. This event is in the early fall and the weather can be either chilly or hot. The lake is a bit cooler than Berryessa (think mid to high 60’s). If you plan to do both the 1- and 2-mile events, be prepared to feel a little cold at the start of the 2-mile. Post event snacks. 

Here is the t-shirt art for this year if you want to pre-order. Also there is a flyer attached for parking info. There are no parking lot vending machines.
