The Old Farmer’s Almanac, a trusted source for long-range weather predictions since 1792, has released its summer 2025 forecast for Ohio. Expect a season that’s both sweltering and soggy. Here’s what Ohioans can anticipate this summer, based on the Almanac’s insights.

Temperature Outlook: A Sultry Summer

The Almanac predicts a hot summer for Ohio, with temperatures climbing above normal. June will start with near-average temperatures. However, July and August will bring intense heat, especially in early to mid-July. After 2024’s record-breaking heat, 2025 could rival those highs. Consequently, Ohioans should prepare for sultry days, particularly in the Ohio Valley region. The National Weather Service also supports this, forecasting a 33-50% chance of above-average temperatures across the state.

Precipitation: Wet and Thunder-Filled

Above-normal rainfall is expected, particularly in the Southern Regions, including Ohio. The Almanac describes a “thunder-filled” summer, with frequent storms. Northeast Ohio, in particular, will see higher-than-average precipitation. For instance, July could bring 4.5 inches of rain in some areas. Meanwhile, August may see scattered thunderstorms and heavy showers. Therefore, keep umbrellas handy and plan outdoor activities carefully.

Regional Variations

Southern Ohio, part of the Ohio Valley, will experience warmer-than-normal temperatures and significant rainfall. Northern and central Ohio, in the Lower Lakes region, will also face hot, rainy conditions. Conversely, the Pacific Northwest and southern Florida may see cooler temperatures. Thus, Ohio’s summer will contrast with drier regions like Texas.

Planning for Summer

With heat and storms on the horizon, Ohioans should test air conditioners early. Additionally, stay updated on weather alerts for safe outdoor plans. The Almanac’s predictions, blending solar science, climatology, and meteorology, offer an 80% accuracy rate, though last winter’s forecast was less precise. Nevertheless, this forecast equips Ohioans to brace for a hot, wet summer.
