What do you think is the climate of the region where Titanic sank? I'm guessing oceanic verging on humid continental? How do you think the temperature patterns go throughout the year (at least, we all know that mid-spring has below freezing nights)?

Any places in the world, you think, would have a similar climate to Titanic's sinking location?

Oceanic and cold. Summer highs would probably be something like 15-18C.

Probably a more oceanic version of Sable Island.

NCEP reanalysis for the day the ship sank (scroll down for hemisphere maps). Anticyclonic and rather cold:

Watched a very cool program on TWC regarding the days around and of the Titanic sinking.

It was a moonless night so moonlight wasn't around to help either. Large 1037 Arctic High over the area.

Temps were warm in the 50s at noontime but the ship passed through a cold front and temps dropped steadily throughout the day and eventually below freezing by late evening. general North winds helped move the Ice Bergs south over previous days.

Basically the clear calm night created a mirage effect. Typically a mirage over water bounces light "up" into the air but that night a phenomenon took place where the light was reflected "down" into the water. This in turn made it seem like the curve of the Earth and hid the Ice Berg in front. Pretty interesting.

This should help the discussion. I was surprised it was so far south. It's at 41° 43′ 55″ N, 49° 56′ 45″ W.

GeoHack - Sinking of the RMS Titanic



The northeast coast of Newfoundland has lots of iceburgs in spring. Looks like the sinking location was directly to the south.

There was a Ship Station in the middle of the ocean a while ago, not that far from the sinking place. It's named "Ship Station D":
SHIP STATION D, WMO REGION 4 DEPENDENT ISLANDS / OCEAN VESSEL STATIONS Weather History and Climate Data

It was rather warm due to its more eastern position, but it can be used as reference.
So we have:

Sable Island 44ºN/60ºW: Feb -1.2ºC; Aug 17.9ºC; Year 7.8ºC
Station Ship D 44ºN/41ºW: Feb 10.9ºC; Aug 20.6ºC; Year 14.9ºC
Titanic sinking place 42ºN/50ºW: ????

Yeah quite different despite the similar latitude. The location relative to the mean position of ocean currents is the key. Looks like the sinking location is located in the battleground between the Labrador Current and the North Atlantic Drift near the southern edge of the Grand Banks, so I guess that the ocean and air temps vary a great deal. It's a zone where SST anomalies are always big due to the conflicting currents and eddies:

Current SSTs, from 16°C/61°F to 2°C/36°F in around 100 miles:

it's really amazing that icebergs can travel that far south.

doesn't seem to be that uncommon either.


Icebergs across the North Atlantic

"Across the Grand Banks, the most active months of the iceberg season (from March to May) create the most problems for shipping lanes across the North Atlantic. During a typical season, icebergs can migrate as far south as 39N across the Grand Banks. The farthest south an iceberg has been spotted was in 1926 near 30-20N/62-32W, approximately 150nm northeast of Bermuda."

crazy stuff.

I believe that the August is around 24/17 C, January around 10/4 C.

I believe so too, but with much cooler lows (say, 12C).

I saw a documentary where a bunch of sailors and/or scientists were at the Titanic's site, paying their respects. The sky was clear and brightly sunny. And they were all wearing sleeveless shirts.

Oh, the 10/4C January seems too warm. I mean, if April nights had subfreezing temps, why would the middle of winter have 4C lows? I'm guessing January would be 7C/-1C.
