This is a good link for
weather and swell reports:
http://www.wrh.noaa.gov/sgx/
We usually click on the map 3 times. Once, to capture the La Jolla area. A second time to isolate closer to the launch. Then the third time to isolate right off of the southern point of the reserve. This usually gives us the most accurate information to the area we will be fishing.
Keep in mind, 3-4 foot ocean swells usually equate to larger surf at other locations, but smaller at the launch, but not always. Lately, 4 foot ocean swells have caused 5 foot surf at the launch,
but that is unusual. With 3 foot ocean swells you are typically
safe at the launch. This website's reports often are more accurate than what you get on TV.
Here is a website we also use when checking current
wind conditions:
http://w9if.net/cgi-bin/torreywx/wx.pl
It is for the Torrey Pines gliderport, just north of Scripps pier, so it is fairly accurate in regards to La Jolla.
Additionally, if you want
tide information, which is useful when launching use this link:
http://www.mobilegeographics.com:81/locations/3220.html
Scroll down the page and look for the date you are going out. Any high tide above 5 feet and you might not be able to drive your vehicle onto the beach. It is also good to know when launching and landing whether the tide is falling or rising. When you go to and from your vehicle, you don't want a rising tide to sweep your kayak away.
We start checking these websites 4-5 days in advance, then check them every day until we go, as conditions can sometimes change significantly.
Be safe, and good luck.
