The Perseids meteor shower is visible each year with the peak occurring between August 12th and 13th. This year up to 80 meteors per hour could be visible as the Earth travels through the debris of Comet Swift Tuttle. Unfortunately a three quarters full moon lighting up the sky means viewing conditions won't be ideal even if the clouds remain at bay.

The latest cloud casts are painting a reasonably promising picture. The Arpege 00z computer model run from Wednesday 9th August shows clear skies early on Saturday night but later on cloudier conditions push in from the west. Nonetheless southern and eastern regions remain mostly clear.

The prospects for viewing the Perseids look reasonable at the time of publication. This morning's Arpege computer model run shows clear spells in all areas during the early part of Saturday night, but cloud pushes across northern and western areas later on. At this range there is uncertainty about the forecast details and the latest run of the lower resolution GFS06z model shows the clear skies lasting longer.
