That remarkable factoid was confirmed by LTV weatherman Toms Bricis on Thursday.
22 out of July's 31 days featured thunderstorms.
In fact July recorded 106mm of rainfall - significantly up on the average figure of just 77mm - but with some truly remarkable regional variations.
The driest place in Latvia in July was Salacgriva on the northern coast, not far from the Estonian border with just 24mm of rainfall.
In contrast, Sili in the south east of the country was drenched with nearly ten times as much - 226mm to be precise, which is a third of the entire annual rainfall average in one month.
Despite its reputation as the "windy city" of Latvia, Liepaja was its brightest in July, recording 292 hours of sunshine, compared to the shadowy gloom of Daugavpils on 189 hours.
