Not in San Diego. We have a total of 7 triathlons from May to October:

SuperSeal in March (Olympic and Sprint)
Spring Sprint in May (International and Sprint)
San Diego International in June (International and Sprint)
Solana Beach Tri in July (Sprint)
Chula Vista Challenge in August (Half, International, and Sprint)
Rock the Bay sometime September
Mission Bay Tri at the end of September.

Challenge Family has also added a sprint race (together with their half distance) on March 10 down in Ensenada.

And also down in Ensenada there is a Draft Legal event (Oly and sprint) in August, by a local team called Tri-Jex.

On top of that I think UCSD puts together a Draft legal race in March.

So, plenty of short course races here in Sunny San Diego.
