The Panama Canal announced Saturday it will reduce the maximum number of ships travelling the waterway to 31 per day, from 32 in August, due to a drought that has reduced the supply of fresh water needed to operate the locks.

That compares to daily averages of 36 to 38 ships per day under normal operation.

Nine ships per day will be allowed to use the new, bigger NeoPanamax locks and 22 per day will be handled through the older Panamax locks.

    I thought sea levels were the same at the same latitude all around the globe. I feel like I’ve been lying to myself all these years now.

      Also tides are not the same on both sides, even if they were the same average level, the tides definitely wouldn’t be synchronized. This would result in very strong currents in the canal, making it impossible to safely navigate. The most common fix for that type of situation is to put… locks in the canal.

      It’s pretty unintuitive because we’re not used to dealing with ocean sized bodies of water in day to day life. Part of the explanation is just that the prevailing winds pile all the water in the Pacific up against the coast, causing higher sea levels on the West Coast. The lower salinity of the Pacific also causes lower water density, which translates to higher sea levels.
