When the man had finished, he filled his pipe and took his comfortable time over a smoke. Then he pulled on his mittens, settled the ear-flaps of his cap firmly about his ears, and took the creek trail up the left fork. The dog was disappointed and yearned back toward the fire. This man did not know cold. Possibly all the generations of his ancestry had been ignorant of cold, of real cold, of cold one hundred and seven degrees below freezing-point. But the dog knew; all its ancestry knew, and it had inherited the knowledge. And it knew that it was not good to walk abroad in such fearful cold. It was the time to lie snug in a hole in the snow and wait for a curtain of cloud to be drawn across the face of outer space whence this cold came. On the other hand, there was no keen intimacy between the dog and the man. The one was the toil-slave of the other, and the only caresses it had ever received were the caresses of the whip-lash and of harsh and menacing throat-sounds that threatened the whip-lash. So the dog made no effort to communicate its apprehension to the man. It was not concerned in the welfare of the man; it was for its own sake that it yearned back toward the fire.
- Jack London, To Build A Fire (1908)

This page is to give a general description of weather conditions in the game’s setting to help the ST and Players during their scenes. The Berlin area has a humid continental climate with warm summers and no dry season. It is located around the 52 degree parallel north at the same latitude as Saskatoon, Sasakatchewan north of the continental United States. Much of the information below is taken from the Weatherspark website. Although based on very recent data, it should be approximate to real historical weather.

Despite its northern location, Europe is warmed by the Gulf Stream. Berlin experiences a more mild temperature than Chicago, being both cooler in the summer and warmer in the winter. Over the course of a year, the temperature typically varies from 26°F to 78°F and is rarely below 15°F or above 88°F.

Daily High and Low Temperature

The daily average low (blue) and high (red) temperature with percentile bands (inner band from 25th to 75th percentile, outer band from 10th to 90th percentile).

The warm season lasts from May 27 to September 3 with an average daily high temperature above 69°F. The hottest day of the year is July 11, with an average high of 78°F and low of 59°F.

The cold season lasts from November 27 to February 28 with an average daily high temperature below 44°F. The coldest day of the year is February 1, with an average low of 26°F and high of 35°F.

Daily Hours of Daylight and Twilight

The number of hours during which the Sun is visible (black line), with various degrees of daylight, twilight, and night, indicated by the color bands. From bottom (most yellow) to top (most gray): full daylight, solar twilight (Sun is visible but less than 6° from the horizon), civil twilight (Sun is not visible but is less than 6° below the horizon), nautical twilight (Sun is between 6° and 12° below the horizon), astronomical twilight (Sun is between 12° and 18° below the horizon), and full night.

Berlin is a generally wet area. Most days out of the year it is likely to experience some form of rainfall although truly bad weather like thunderstorms or heavy snow make up only 10% of all forms of precipitation.

Historical Moon Phases
For ease of game, strict time keeping is not being done. However, there are historical moon phases online we can use to keep a general track if needed. We can use Calendar-12 as a resource.
