How to read the graphs

The “Year at a Glance” graphs may seem a bit confusing at first …. glance. They contain an enormous amount of data. For every day of the year there is color coded data for that day’s high and low temperature, sea temperature and the amount of rain that fell on that day.

Here is a small overview of a graph:

Starting at the top of the graph is the first day of the year and the days advance clockwise around the graph.

The circle graph is made of a series of circles. This guide will first describe the outermost circle and then work inward towards the center describing the others.

The first outermost circle contains 3 types of information. First, the month, second the year (18 = 2018) and third the season. Each season has it’s own color in the graph. Winter – blue, Spring – green, Summer – orange, Fall- brown. If you look closely at the above image you will see that the outermost circle is brown (Fall) in December until it turns blue the 21st of December (Winter). Also if scroll up to the small overview of a graph you can see where the seasons change in the entire graph.

Still working inward, the next circle is simply the number of the day of the month. As we will see below, the amount of rain, if any, is also indicated on the day.

The next circle is the color coded maximum temperature for each day. Also since it is sometimes difficult to judge what color is exactly what temperature you can click on the temperature color to see the data of the temperature for that day. As an example, look a February 13 in the image above and you can see that the color corresponds to 20.2 degrees. The list of colors in the temperature scale will be shown below.

The next circle is the color coded minimum temperature for each day. This works exactly as was explained for the maximum temperature above.

Continuing inward there is a mostly blank circle. When there is rain data (to be discussed below) you will find it here.

Again, continuing inward is the circle of color coded data for the sea temperature of each day. This works exactly as was explained for the maximum temperature above.

Continuing again inward there is another mostly blank circle. When there is rain data (to be discussed below) you will find it here.

Finally we arrive at the center of the circle with the temperature and rainfall scales where you can find which temperature and rainfall corresponds to the colors you see in the graph. Here is a complete view of these scales:

Rain: A colored blueish line corresponding to the color for the amount of rain that day is drawn from the red circle, which has “Rain scale (mm)” printed above it. Below the red circle is the Rain Scale showing the different blues used to show how much it rained. A common mistake is to think that the starting point of the rain line drawn up to the day it rained corresponds to the position near it on the Rain Scale. Remember, as you can see above the rain lines start at the red circle, not the rain scale.

Three more details. First as you can see in the image below, if you click on any of the rain lines in the mostly blank circles you see the amount of rain the blue of the line represents. Secondly, the blue of the rain line is also seen on the day of that rain. You can see that in this image and the one that follows it. The more the rain the darker blue the number of the day. Compare October 14th to October 9th. Thanks to coloring the day the same as the rain color you can see every day of rain for the whole year at a glance.

Finally, the third and last detail. While clicking on any of the color coded data shows the exact data for the color, clicking on the date does nothing. It is not active.
