It's time once again to prepare yourself for Outside Lands, which is happening this weekend (I know, it sneaks up on you), August 7-9, in Golden Gate Park. As usual for this time of year, the weather in the park is not going to be super ideal for music festival-going, though it won't be awful either, and you might even get a little bit of sun if you're lucky. But as we look ahead via Weather Underground we can say right now that we will not be lucking out with a perfectly clear and sunny day (that looks like it won't arrive until next Monday), and all three days will probably have a similar pattern of fog with late-day sun, with the added bonus of a bit of rare August rain. We got some in July, so why not?

Yes, there's a 40 percent chance of rain overnight and into the early morning hours of Saturday, so if that timing remains accurate it won't impact your concert-going too much, though it could make for some dampness and/or muddiness out around the Polo Field Saturday afternoon.

Other than that, you may see the warmest temperatures on Friday afternoon, with a high of 70 predicted — at least in the Western Addition, that is. You'll likely see a bit of sun as St. Vincent, Drums, and Wilco go on in the late-afternoon, early-evening hours, though in that part of the city you could also be under fog by then while downtown gets some sun.

And come Sunday, for Elton John, there will be partly cloudy skies, a high of 71 in some parts of town, and an evening low of 59 degrees with some light winds predicted.

Please refer back to last year's very handy guide to how to dress for Outside Lands, because just like every year there is the distinct possibility you will be freezing your ass off if you don't prepare.

And, once again, you should not plan to drive as parking in the Sunset and Richmond will be a nightmare. The #5 Muni bus and the N train remain the simplest and quickest ways in and out, and don't be dumb and accept an Uber surge fare like people did last year, only to sit in stupid traffic and end up spending $300 or $400.

Tickets for the fest are sold out, but plenty are up on Craigslist and StubHub, with three-day tickets starting at $375, and single-day tickets starting around $220.
