The Glastonbury 2023 takes place between June 21st and 25th at Pilton, Somerset. June has a reputation for bringing mixed weather to the UK and a number of festivals in early summer have had to contend with muddy conditions in recent years.
There is even a term for the unsettled conditions which can develop at this time of the year - the “European Monsoon”. It refers to the strengthening of westerly flow during June and July, increasing the risk of wet weather. Unpredictable and often weak, it’s most likely to occur in late June or early July. This could explain why Glastonbury is associated with rain and mud, but records show not all festivals have coincided with poor weather.
On TWO a range of features have been added recently to provide a more in-depth view of the weather prospects than is often the case with web site or app based forecasts.
The easiest and quickest option which updates 4 times daily.
Gives an hour by hour view and allows you to change the computer model data used at the tap of a button to check for forecast consistency. Also, the rain and storm percentage chance is shown if you select the UKV model.
Uses multiple computer models to give a percentage chance of rain falling on a given day.
Uses multiple computer models to give a percentage chance of thunder on a given day.
Uses multiple computer models to give a percentage chance of temperatures exceeding different thresholds on a given day.
Ensembles forecast graphs showing upper air temperatures, rain, temperatures, pressure and mean wind speeds and snow depths (although we don't expect you to need those!)
Despite the in-depth forecasts and use of multiple computer models, it is important to remember that showery rain in the summer months can be very localised. The upshot is conditions can vary a lot over even short distances.
If your phone or device supports it, you can request forecasts by voice control.
1) Just tap the microphone icon near the top of the screen (If there isn't one your device doesn't support this feature)
2) Say, "weather for Glastonbury" or "hourly weather for Glastonbury" or if you're at the festival you can try "my weather" which will locate you (if you allow it to) and show the latest forecast
3) Say "radar" to check the latest rain radar which provides the current view rather than a forecast
The prospects could be described as mixed.
If you'd like to check things out for yourself using charts and data sets from a huge range of computer models then take a look at the Model Inventory.
Going ad free on the web site will also give you access to additional charts from the high resolution UKV model. They provide zoom and bespoke options. See Advert free access on our website for more information.
