Luggage and bags:
i took a backpack and a large purse. it's not fun to have to carry around a lot of bags in this city. there are a lot of people walking around and you don't need to take up anymore of the sidewalk than necessary. of course if you have the money to spend or rent a car, having more bags shouldn't be a problem.
Clothing/Shoes/Weather Gear: bring a coat or jacket no matter what time of year. san francisco's weather can change quickly and often does. expect fog in the mornings, a chill at night, and if you're down by the water a jacket could possibly be a must, i was very cold and wind blown when down at fisherman's wharf.
I heard several people say 'My worst winter was the summer in San Francisco...'
Expect good weather in spring, more rain in the summer... around the bay, there will be always be that cool ocean breeze/wind, so no shorts necessary (brrrrr...), and as soon as the sun is gone, a warm sweater and a jacket are a necessity! Otherwise, wear whatever you feel comfortable in, after all, you are in San Francisco... *g*
Miscellaneous: I underestimated the amount of money i would spent in SF... i went waaaaaaay overboard, mostly to the fact that SF is expensive in general with almost everything...
(Most expensive housing in the states, was that right?) But none the less, the money is worth being spent in this city... just be prepared, thats all...
Ok people, here's your one warning: this is San Francisco, NOT california. Don't be wearing your tank tops and shorts and then complaining at 3pm when the fog rolls in. How many time did I hear 'does it usually get this cold here in the summer?'. The answer is YES! It'll be warm during the day (up until the fog rolls in at 3) and then it's light jacket weather. Please people, just bring something with sleeves for later in the day.
Camping/Beach/Outdoor Gear: Don't come here expecting to go to the beach. Typical beach wear in SF is a sweater, a windbreaker, a strong hat, pants and shoes.
Miscellaneous: If you leave the city, be warned, it's usually a lot warmer inland (East Bay, Marin, Napa). Wine Country, especially can get downright sweltering in the summer... this is shorts weather kids.
Clothing/Shoes/Weather Gear: Be advised that San Francisco can be foggy, even in the summer. Make sure you bring an extra jacket, even when the sun is fully out. In the picture you can see the fog banks waiting in the bay. By early evening the fog advanced upon the city and it got quite chilly!
San Fransisco is always colder than the rest of California, so bring a sweater and some pants just to make sure you won't have to worry about freezing when you go sight seeing.
Photo Equipment: It's very cheap to develop film in the States so do it while you´re there if like me you're from Sweden!
Miscellaneous: If you like shopping as much as I do I have a few tips!
Shoes: go to one of the many 'Payless Shoesource' stores throughout California. Wonderful shoes at very low prices.
Sam and Libby, another chain of stores throughout California. A little more expensive but not that much. They have a little more exclusive looking shoes, which are very nice!
Clothes (and other things also): I would highly recommend the 'out-let' store: Ross. Ross is another chain of stores throughout CA. In a Ross store you'll need a little more patience than in a usual store, but it's worth it. You'll find all kinds of stuff from designer dresses at soooo much lower prices than usual to designer towels and shoes. Not everything is designer made of course. Ross sell the remaining items that a normal store don't. So you can not be sure to find this or that special dress in your size, but if you do, you will have saved lots of of wonderful dollars to spend elsewhere!
Spring: 3 sweaters. dark jeans.
Summer: 2 sweaters. 1 tshirt. dark jeans.
Fall: 3 sweaters. dark jeans.
Winter. 3 sweaters. dark jeans. Umbrella.
Clothing/Shoes/Weather Gear: Make sure you bring a sweater and jacket because it gets really chilly at night. Also, good walking shoes because you will need them for walking up all of the hills!
