Is there one main resource that tells you when each town's lifeguards go on duty. I usually surf an unguarded town so it hasn't been an issue, but we want to hit some other breaks here and there. Is the general rule that they start on Memorial Day or the 4th or something? How about the typical hours for guarding? This may be obvious for some, but lifeguards haven't be an issue for me in about 8-9 years. I tried checking some towns websites but didn't see anything relevant. Thanks for any info!
