Shade Shifts. Knowing where it shifts before you set up your outdoor shades will help you avoid hot, shadeless summers.
Plan your shade in advance.
If you know where the shade will be, you'll know which way to face the patio, where to put the awnings (and what kind to get), and you'll know if you'll need overhead shade or vertical shade or both.
There are 3 basics you need to know for shade planning:
1. Shadows fall away from the direction of the sun.
2. Shadows are longest when the sun is closest to the horizon; shadows are shortest when the sun is overhead.
3. Know where the shade will be when you need it.
This seems really simple at first. But have you ever set up your outdoor shades in the spring, only to see that near the end of summer you're not getting the shade you'd hoped for? Not having a shade plan may be the most common mistake people make when setting up their shades. Not such a big problem if you're dealing with an umbrella you can move around. But what if it's a patio? A tree?
Permanent shade structures can be expensive. Even temporary shade structures can be hard to move around. Planning your shade can help you set them up right the first time. Shade planning can be as simple or as precise as you need. The more expensive and permanent your shade structure and the more people it affects, the more important precise shade planning becomes.
The first two basics may be simpler because we can observe them every day. These are helpful for short term shade planning. The third basic — knowing where the sun will be — can be a little trickier but is especially helpful for a long term shade plan.
The first step in shade planning is knowing where the sun will be is to know approximately where north or south, east and west are. Here's how. Everywhere on earth the sun rises in the East and sets in the West. Standing with the morning sun at your right means you are facing North and your back is toward the South; standing with the afternoon sun at your right means you are facing South and your back is toward the North.
When you face North the sun will rise on your right side and set on your left side.
On the summer day in the illustrations below, the structure gets almost no shade on the South. (We're looking at the picture facing West so South is to our right.) Keep in mind the "structure" could be anything: a building, a tree, an umbrella, etc. Notice the place that gets shade during the hottest part of the day is a small area close the to North side of the structure. This is where the shade will fall whether the structure is a building, canopy or even a tree.
This short term shade plan tells you that close to the North side of the shade structure is where you should be to get some shade through the hottest part of the day. For more shade you'll need to add some kind of shade structure to the South side of the existing structure.
Take a look at these images. They show you how the sun's position changes from morning to afternoon of a summer day. Areas that get shade in morning may not get it in the afternoon. (Please note this is just for general information. Locations South of the equator would show shade to the South instead of the North.)
Armed with this information, you can set up shade in your area to protect you in any short term or temporary situation.
But let's say you want shade for more than a few hours or a few days. Maybe you want it all summer long or all year long. Have you noticed that shade is harder to find in the summer than in the winter? I always thought it just seemed that way because it was hot. But no, there actually IS less shade. That's because the sun's position is different in the summer than it is in the winter. This is a result of the predictable seasonal shifts of the sun's location. A shade plan that takes advantage of where the sun will be throughout the year can help you avoid some costly and disappointing mistakes.
Sometimes people will build decks or patios just as winter is ending in order to be able to use it from the first warm day on. They have it built and start enjoying the early spring shade immediately. But as early spring turns to late summer they notice areas that were getting shade four months ago are getting no shade whatsoever. The shade continues to shift until finally in winter, about the time they had it built, the shade finally reaches back over to cover it.
Without knowing where your shade will fall year-round, you may risk making investments and plans that are virtually unusable. What a disappointment! What a waste! A little more knowledge can help you prevent this. The same knowledge can help you correct it by showing you the best place to position additional outdoor shades.
The second step in knowing where the sun will be is to know approximately how the sun will shift throughout the year.
* north of the equator: the summer sun rises in the northeast, peaks nearly straight overhead, and sets in the northwest; the winter sun rises in the southeast, peaks lower toward the south, and sets in the southwest.
* south of the equator: the summer sun rises in the southeast, peaks nearly straight overhead, and sets in the southwest; the winter sun rises in the northeast, peaks lower toward the south, and sets in the northwest
Notice that even though it's the same time of day in both pictures above, summer shadows are much shorter than winter shadows. If you were to set up a deck in the northwest winter shade, by summer that shade would have completely disappeared, leaving your deck and guests to bake in the summer heat. This shows how critical it is to plan your shade in advance and understand where shade will be during the times that you'll need it.
If you live north of the equator summer shadows will always be toward the north.
If you live south of the equator summer shadows will always be toward the south. Keep in mind summer falls in different months north of the equator than it does south of the equator.
When in doubt, plan for short shadows. When the sun is hottest overhead is when shadows are shortest.
This may be all the information you need to plan for your shade needs. But you can get even more precise about the sun's location by using some helpful tools.
Sun path calculators and computer applications help you predict the position of the sun throughout the course of a day, season or year. These tools are enormously helpful in situations where sun protection is critical, such as at schools, playgrounds, and anywhere children, the elderly or the public need protection, or where permanent shade structures will be installed (Any company installing outdoor shades for you should be able to help position your outdoor shade so it will be most effective for your needs). The more precise you can be in predicting the sun, the more use you'll be able to make of its shade.
But the more precise you get, the more complicated it gets. These calculators and applications can be expensive and extremely difficult to understand. For something much less complicated I highly recommend doing a shade audit for your area.

Your shade planning will help you come to a shade solution that will likely consider how temporary or how permanent the shade should be. It would likely consider the shade structure's placement and maybe even the shade material. Will the look of your outdoor shade be important? Will it need to enhance the look of your home or business? Or is function the only consideration? And your personal shade solution must of course fit within your budget and timing.
Once you understand when and where you'll need outdoor shade you'll need to decide how to supply it.
Get some ideas at our page on shade structures. This page will tell you about your many shade options,the qualities and features of different shade structures. You'll learn about advantages to permanent, temporary and portable shades.
We also have a page on shade materials that you can use to customize a shade structure.
Your personalized shade solution may be as simple as selecting a single outdoor shade structure that will protect any given area for a few hours, perhaps a few umbrellas or a canopy. Or it may incorporate natural shade (your local plant nursery can be tremendously helpful in recommending plants that will provide shade and will thrive in your area), and a number of different manufactured outdoor shades. An example might be a combination of trees, a patio cover and outdoor shade curtains.
We hope you will find what you're looking for and perhaps pick up a few new ideas.
