I. Short-Term
The short term increase is easy to explain, fuel sold in California is special blend not sold in other states. Closed or hobbled refineries have a greater impact when out of state fuel cannot make up the difference. One solution is to switch to the winter blend early, which the Governor has ordered. Moonbeam saves the day!
But it was government mandated fuel blends that were in short supply, not oil and certainly not usable gasoline. Just the particular blend of additives that the State requires. This is part of the reason California has notably higher gas prices than surrounding states (most of the rest is higher gasoline taxes).
Many are quick to point out that the high gas prices are due mostly to the high price of crude oil. Here is a neat graph:

Breakdown of gasoline prices by category:
http://www.exxonmobilperspectives.com/2011/04/27/gas-prices-and-industry-earnings-a-few-things-to-think-about/article_495_-breakdownofagallonofgasoline/
Taxes: 12% (for roads, I guess)
Distribution / Marketing: 7% (Getting the gas to a gas station and operating said gas station)
Refining: 13% (Transforming crude oil into usable gasoline - no small feat)
Crude Oil: 68% (Exploration, extraction and delivery of crude to refinery)
Here “taxes” only refers to direct tax on the final gasoline sale, not the taxes associated with extraction of crude oil, or taxes paid by the gas station owner. Regulation is another form of taxation that costs consumers, but is often hidden from the calculation. Here, some percentage of the “refining” cost is paid to comply with fuel blend mandates. So the actual burden of taxes is much higher than 12% - but we are still missing the biggest tax of all...
II. Cost of Crude
After you see that 68% of the cost is crude oil - the next logical question is why are crude oil prices so high? Exxon has the kind of answer Americans like: “Well it is not rising as fast as most other commodities!”

This gives us a hint that the problem is larger than gasoline and crude oil.
The rising cost of crude oil is often blamed on low supply, high demand. The problem is, supply (of crude) is robust, demand is weak:

Besides - if all the prices are going up, then inflation is the culprit. It is not the supply and demand of gas that is the problem - it is the supply and demand of the dollar being used to buy the gas. There are lots more dollars, so they are all worth less :( These actions have consequences and we have been warned:
III. FED policy and its effects:
Money Supply booming, seeds of the next Greater Recession:
http://www.forbes.com/sites/michaelpollaro/2012/03/17/money-supply-booming-seeds-of-the-next-greater-recession/Others will point to speculators and claim that their greediness is driving up the cost. But for every purchaser that buys speculating on higher prices, there is a seller, who is speculating on lower prices. There is another category of buyers, who purchase commodities because they are a better “store of value” than dollars. Here again, people acting to avoid the anticipated effects of dollar inflation.
This is more a of a problem recently, because other countries would pay for our inflation. It is/was called the “petrodollar”. Most oil producing countries agreed to only sell their oil for dollars. This created a world-wide demand for dollars and stabilized oil prices for dollar purchasers (us). Most countries figured out the scam and have started trading in non-dollar assets. This includes Iran - who we are now waging a currency war against (coincidence?) Inflation and militarism go hand-in-hand, but more on that another time. http://www.caseyresearch.com/cdd/demise-petrodollar
If the problem is not with the gas, but with the dollars - then gas prices, denominated in some other currency, should give a more accurate picture. Indeed, denominated in gold, gas is at all-time lows:

What do we get for all this government intervention? Here are some warnings from posterity:
Thomas Paine:
“Paper money is like dram-drinking, it relieves for a moment by deceitful sensation, but gradually diminishes the natural heat, and leaves the body worse than it found it.”
Ludwig Von Mises:
“One can say without exaggeration that inflation is an indispensable means of militarism. Without it, the repercussions of war on welfare become obvious much more quickly and penetratingly; war weariness would set in much earlier.”
Ernest Hemingway:
“The first panacea for a mismanaged nation is inflation of the currency; the second is war. Both bring a temporary prosperity; both bring a permanent ruin. But both are the refuge of political and economic opportunists.”
TLDR: High gas prices are partially the fault of government and mostly the fault of FED policies.
