It looks like Google is slipping and there is a bug in their Chrome browser that may or may not be effecting the Swellinfo surf forecast pages for you. If you are using Chrome version 29, then you may notice that the Forecast page Timeline and Maps work on the initial page load. But, then if you refresh the page or view another forecast page then both the timeline/maps dissapear.

The problem is occuring in my browser. Chrome version 29.0.1547.62 m
This is a documented bug, and should be fixed in the Chrome updates soon.

Here is how you get around it:

Option 1) In Chrome, got to Settings->Advanced Settings. Unclick "Use Hardware Acceleration when available". Then restart Chrome, and it should be fine.

Option 2) Use another browser: Firefox, Internet Explorer, Safari, etc...

Feel free to let me know if you have Chrome v29, and are having problems or not, and if this has been helpful.
