Weather

From Ahoypedia

Weather influences many aspects of the Ahoy experience. From impacting the Sailing and Naval Combat mechanics, to changing the rate of production of Goods. In addition to mechanical influence, weather also greatly impacts the visual landscape.

Weather in Ahoy is broken down into a few layers. The highest level of this represents the Day and Night cycle, and the passage of time. Further to this, the 8 key geographic regions of the map provide unique fixed Climates. Seasons are constantly cycling and influence the frequency of certain Dynamic Weather systems.


Time

Time in Ahoy runs in a fixed and unchanging cycle. Every Ahoy 'day' (24 hours) passes within 5 real-world hours. Therefore the passage of time in Ahoy works as follows:

Game Time Real Time
1 Year 1680 Hours (70 days)
1 Month 140 Hours (5.83 days)
1 Week 35 Hours
1 Day 5 Hours
1 Hour 12 Minutes

Seasons

Seasons in Ahoy do not follow the expected 4 seasons (Spring, Summer, Autumn/Fall, Winter) but instead the Tropical 2 Seasons pattern of Dry season and Wet season.

The Dry season (referred to as Summer) runs from 1st November to 30th April, and the Wet season (referred to as Winter) from 1st May to 31st October.

In Ahoy, the Dry and Wet seasons effect the gathering of natural resources, the frequency of certain types of Flora and Fauna, as well as minor adjustments to the passage of the Sun & Moon, represented correctly in the sky.

Tropical climates do not experience large fluctuations in the amount of daylight between seasons.


Climate

Climates are a set of fixed frequency modifiers to Seasons based on defined regions of the map which represent a significant shift in vegetation, geology, or in this case, climate.

Here is a table showing the percentage chance of a weather type, in a certain region, based on season (Summer %/Winter %)

Dynamic Weather

Dynamic Weather is the representation of individual weather systems that are capable of movement around the world of Ahoy. These systems are influenced by the direction and speed of the Wind in it's current location. Weather systems are 'spawned' and 'removed' at random, but the rate this occurs is influenced by the seasons and climate.

Dynamic weather systems can be of varying intensities, but are usually represented through worsening conditions.


Doldrums

Doldrums are difficult to spot at a distance, but are represented by a significant lack of waves and clouds. They can reduce the movement of Ships significantly, and therefore should be avoided. Doldrums decrease the speed of wind in the area to an absolute amount (to be decided).

Fog

Fog has a purely visibility-based impact, and is often present towards the start or end of a day, but can sometimes persist further into the day depending on the current season.

Light Rain

Light rain adds a boost to crop growth, and reduces visibility in a similar way to fog. It is often fast-moving and brief, but does cover large areas of the map at a time. Light rain increases the speed of wind in the area by a relative amount (to be decided).

Heavy Rain

Heavy rain can cause significant visibility reduction. It does not improve crop growth any more than light rain. Heavy rain increases the speed of wind in the area by a relative amount (to be decided).

Lightning

(Thunder and) Lightning can occur within heavy rain or tornado systems. Predominantly it is a visual and audible effect which adds atmosphere.

There are no current plans to implement physical Lightning strikes, however it is under consideration.

Tornado / Water Spout

Tornadoes (or Water Spouts, when over the water) are a rare event greatly influenced by the regional climate and seasons. These systems are extremely fast-moving, and often cause some damage to structures and ships if the path passes over them. However, none of this caused damage is irreversible, and often just incurs a cost on the owner to repair. Alternatively, ships can avoid these systems. Tornadoes increase the speed of wind in the area by a relative amount (to be decided).

Wind

Wind is represented in Ahoy using a grid-based system. The map is split up into grid segments, and each segment stores the following data.

Wind Direction

Wind direction is based on a pre-determined 'directional map' which decides the 'default' wind direction of an area for each month of the year. In addition to the default value, there is additional value 'noise' applied to randomize the appearance of the wind direction over the course of multiple days or weeks.

Wind Speed

Wind speed is also based on a pre-determined 'speed map' which is designed based on the geography of the surrounding areas. The wind speed is also stored as a value per month, per grid segment. It also receives a randomization through additional value noise.

In addition to these 'base values' wind can also be influenced by Dynamic Weather systems. These weather systems can increase or decrease the base values of wind in an area by a relative (e.g. Heavy Rain) or absolute amount.
