Wetsuits will not be allowed in the 10k races at U.S. Open Water Nationals in Castaic Lake after the lake was recorded at 69 degrees Fahrenheit at 9:30 a.m. local time Friday morning, just 90 minutes before the men’s race was scheduled to get underway.

According to a new rule passed by FINA and adopted by USA Swimming, wetsuits would have been optional at temperatures below 68 and required if the water was colder than 64.4 degrees, but the lake warmed up just enough to surpass that threshold.

Some coaches and swimmers had been concerned about the potentially chilly water and the last-minute changes to the wetsuit rule (announced less than two weeks before the race), but those concerns are avoided with the race-day temperature reading.
