The leaders of Russia, the United States, the United Kingdom, France, Germany, Italy, Japan and Canada will begin a three-day summit in St. Petersburg Saturday.
Weather services had forecast short spells of rain in the region.
"Three aircraft are engaged in the effort at the moment," said a temporary headquarters in charge of ensuring favorable weather conditions during the G8 summit. "Up to ten planes could be engaged if necessary."
Weather services said air temperatures in Russia's second largest city would be above 20-22 degrees Celsius (+68-72 degrees Farenheit), and promised northern winds at a velocity of 10-15 meters per second (32-49 feet).
Clouds will also be dispersed Sunday, when main summit events take place, the headquarters said, adding that it was so far unclear whether sky clearing would be required on Monday, the final day of the summit.
