St. Petersburg experienced a colder and wetter May than usual, despite a brief warm spell in the third decade of the month, according to chief meteorologist Alexander Kolesov. The month’s overall temperature averaged 0.7 degrees below normal, making it the sixth coldest May in the past 25 years.

The beginning of May was marked by cold temperatures and unexpected snowfall, reminiscent of the previous year. While the weather improved mid-month, offering hope for a repeat of the hot late-May conditions of 2024, the third decade ultimately fell short.

Despite being the warmest part of the month, the third decade’s temperature was still 5 degrees lower than the previous year’s figures.

In addition to the lower-than-average temperatures, sunshine was also lacking, reaching only 92% of the monthly norm despite shining for 29 days.

Conversely, precipitation was significantly higher than normal, reaching almost one and a half times the expected amount. This surpassed the previous year’s rainfall, which was only 14% of the norm, but remained less than the record-breaking May of 2021, which saw almost 300% of the usual monthly precipitation.
