BBC Weather: Getting More Granular

Since my last blog post 3 months ago the BBC Weather team have been quietly busy. We have been working closely with our colleagues in the BBC Weather Centre to move to a new, more complex forecast data model from the Met Office.

This new data set gives us more granular data, both in terms of the number of forecast points across the UK (a tenfold increase), and in terms of granularity and frequency of the forecasts themselves.

The new data was rolled out in time for the start of the Torch Relay, which enabled the BBC Weather Centre to give more detailed forecasts along the Torch Relay route. Today we rolled out a change to the BBC Weather website to make the most of this rich new data set.

A Tight Squeeze

The most dramatic improvement we have implemented today is hourly forecasts for UK locations.

You can see in the image below that 24 hours' worth of data is a lot of information to squeeze onto the page and still make it readable and user friendly.

We developed and audience tested various layouts, and finally came up with two options.

The first view is a 'graphical' layout which shows the forecast data divided by time on the horizontal axis and the range of temperatures on the vertical axis. The scale of the vertical axis automatically adjusts depending on the maximum and minimum temperatures, maintaining a fixed space on the page.

The first day shown is a moving window, showing the remaining weather for the current day, whereas the following days' forecast shows a full 24 hours of weather.

As you might expect the granularity of the weather data reduces the further ahead in time you go. So as you move from two to three days ahead, the forecasts go from hourly to three-hourly. In the near future we will also be introducing 'Further Ahead' extending us out to nine days of weather forecasts.

Back to the challenge of space… in addition to the most common forecast data that users want (temperatures, weather icon/type and wind speed) we had the challenge of also displaying additional information like humidity and wind direction.

To keep things nice and compact we've introduced a hover-over state, which shows all the additional forecast data:

The hover box, for 1600hrs, shows humidity, visibility, pressure, wind speed, and wind direction

Additional weather forecast data which comes up when you hover the mouse over a weather icon.

However we also recognised that many users prefer an expanded tabular view of weather forecast information, which does not rely on the hover-over box, and is therefore more accessible.

This second, 'table', layout (the button to switch between the views is below the "Find a Forecast" box) takes up more page real estate but gives the full detailed forecast at one glance, which may be preferable to some users.

If you're using cookies, the browser should remember your preference the next time you come back to visit the BBC Weather website.

The same detailed information as in the boxes in number 3, but set out in a table.

To accommodate the new page design we moved around other elements on the page.

You will now find the regional forecast text summary under the forecast data, in line with the environmental summary data (UV, Pollen and Pollution) and the regional forecast video.

In the near future we'll be further improving this section by adding colour scales to highlight the severity of the environment summary data, much like we use colour for the temperature scales.

Better World Weather

In addition to delivering hourly forecasts for UK locations, we now also have three hourly forecasts for international locations - a vast improvement from our previous day/night only forecasts.

You can see in the example below that we have adapted the same layout of graph and table views to work for both UK and international forecast data.

Other Improvements

In my last post I mentioned we had implemented RSS feeds on our forecast pages, but one reader keynet pointed out that we had in fact only implemented the three day forecast RSS feed:

The "Observations" RSS feed appears to be broken since Monday this week, the example given on your RSS page for Manchester (http://newsrss.bbc.co.uk/weather/forecast/9/ObservationsRSS.xml) for example gives "Temperature: N/A (N/A), Wind Direction: N/A, Wind Speed: N/A, Relative Humidity: N/A, Pressure: N/A, N/A, Visibility: N/A" London is same. Forecasts are still working though.

In today's release we have also added in the Observation RSS feed to our forecast pages, which is available from the same RSS icon (the unblurred box below).


The rest of the page blurred to draw attention to a box that includes RSS links

The observations RSS feed is now available alongside the 3 day forecast RSS feed

We've also added a link directly to the 'UK Monthly Outlook' from the weather homepage http://bbc.co.uk/weather as many users didn't know it was accessible from the 'More UK Weather' page.

As mentioned above we've got a few more improvements coming soon - nine day forecasts and improved designs for the environmental data. I'll come back with another blog update as soon as we release this next set of improvements, and in the meantime I look forward to your feedback and comments.

    A bit like this great Android widget - https://play.google.com/store/apps/details?id=net.veierland.aix. Do you have any plans for developing an app for Android?

    Love the new changes, they are what I (and presumably many others) requested in past polls. Looking forward to additional developments. This makes the best weather site even better.

    Excellent changes. Love the design (particularly the first one). I hadn't come across the Weather RSS feed before, that's a great idea!

    It's a really innovative idea! The weather is much easier to scan!

    My only complaint is that it looks strange when you're looking at today's forecast and some of the graph columns are empty. Plus, it looses that wave appearance, since it's been chopped in half. It also means that the place where I usually look to see the weather at 9 o'clock now contains the weather for 16 o'clock. Maybe you should show the forecast for earlier times in the day, but make them monochrome, or something.

    Oh dear, am I the only one to not like the new format? I am finding it difficult to take in the information as the page now looks so 'busy'. Shame, I liked the last format better.

    I agree with Lindy, im not keen on the overload of information on screen. I have been an avid follower of the BBC Weather website and forecasts, and there is one thing that i still dont understand. When the BBC went digital, they dropped the 'old' weather symbols. The Website looked good with better weather graphic icons. Since the update they have gone back... Why?

    Much better, but I agree with #4 that past hours could be greyed out to complete a full day.

    Because they fit with the new GEL theme. I must admit they took some time getting used to again.

    I agree with Josh that it looks a bit strange in the today view with the empty columns. I also agree with other's that the full 24 hours on a single page looks like a bit too much. Did you experiment with a scrolling view showing for example 8 hours at a time, working something like TV guide sites (eg zingzing) where you can click on a time period or just drag scroll continuosly.

    I agree with Linda the page looks too busy and there are empty columns. Also I notice that the post states that the forecasts are based on 'new, more complex forecast data model from the Met Office'. How come then that this forecast doesn't match the Met Office and they seem to now give forecasts for different wards within my town whereas the BBC seem to use the same forecast as Portsmouth. I think the BBC has some catching up to do in the mean time I will use the Met Office.

    Whilst the new site gives more information . I have great difficulty in printing a copy for use during the day

    Ohh dear - this new format is just not working for me. I used to print a copy of the page and display it on my Guest House information board. The guests found it easy to use and it gave just the right amount of detail. This new version just has too much information and my guests can find it overwhelming.

    Please change it back.

    The BBC just can't get it right. Benchmarking would help. Instead of changing the way the weather is presented every 3 months, why not check other services (e.g. weather.com, wetter.de etc) to get an idea how it can be done instead of inventing new and confusing things. Why can't you give 2 options, a summary of daily weather and and an optional hourly forecast instead of forcing an hourly forecast on us which is too small, even for the iPad? Where is the chance of rain? What do the icons mean? A cloud with one rain drop, is it a bit of rain or is it low rain risk? Utterly confusing...

    Comment 1 by Andy.

    I second your endorsement of the Aix weather app and also recommend the Fancy Widgets app ( https://play.google.com/store/apps/details?id=com.anddoes.fancywidgets&feature=nav_result#?t=W251bGwsMSwyLDNd ) which I use in conjunction with it.

    I agree that I would be interested in a BBC version.

    On this new weather page format, the wave format works very well in the tight 24 hour granular format for today and tomorrow but is strangely difficult for the eye to follow in the more spaced out 3 hour format for days after that where it might be better to revert to a flat line presentation.

    In respect of rain, a percentage figure would be helpful.

    Jo, a serious bit of data overload when it comes to the weather but I quite enjoy the new format! I agree with Ivan above on maintaining the flat line style of presentation when it comes to the shorter time (3 hour) formats

    @ John F, why don't you just press the picture of the printer and you get a one page summary

    If that is how it is supposed to look, it is a complete mess! Perhaps you could give us the choice of hourly or 3-hourly display in the settings menu? I thought the wavy line might be to indicate the height of the sun (when out) or is it temp? It gives a wrong impression when it suggests you can predict every shower - you can't - but perhaps some people welcome the extra data. IMHO the new presentation is a mess.

    Incidentally I tried the contact button on the page because I actually thought the webpage was broken and wanted to notify you but only found a closed blog from last year.

    You need a simplified view for people in a hurry or with a small screen, plus a more detailed view like your table view for anoraks. What *would* be useful is the ability to merge two local forecasts if you live half way between two towns for example - that would be a lot more useful than messing up the graphics Again.

    Please would you ask your colleagues at Ceefax to add the Pollen Count page 426 to the Weather Index page on 400: with so many Ceefax Weather pages no longer being updated, it's good to have the Pollen Count report for as long as Ceefax is still running?

    I think i am going to give the mobile site go for the quick overview (so for example http://news.bbc.co.uk/weather/mobile/forecast/8 )

    I hate the new layout - the readability of the temperature number itself has been compromised for a silly wavy line that takes up enormous space - who really is going to primarily use a trend line across the day (cooler in the morning and the evening, warmer in the middle bit - duh!) to make judgments about what temperatures can be expected? Isn't the trend immediately obvious when you look across the numbers.

    Oh, and as usual if you opt for the option that takes you back some way towards what you were happy with before you are punished. In this case by a madly busy table with far more unrequested detail, redundant headings above each section ('temperature' 'conditions' etc) and wind directions added pointlessly in letters below an arrow that clearly shows graphically where the wind is coming from.

    There is huge history on ill-thought-through change on this site, and I happily look forward to the site grudgingly being forced to lose the most childish aspects of these changes over the coming months.
