Augusta Future Trends
Maine · US States · Trend-based projections to 2050
This page uses Augusta's own 50 year weather record to project one trend line forward to 2030, 2040 and 2050, with a Best and Worst scenario range built from the trend's own statistical uncertainty. For where that trend has already gone, see the Climate Capitals Trends, or for current and historical day-to-day weather, see Meteo Capital Cities.

Frequently asked questions about Augusta's projected trends
How warm will Augusta be in 2050?
Extrapolated from Augusta's own record since 1976, the average daytime high in 2050 works out at roughly 13.8°C, up 1.0°C from 2025. This is a straight-line projection of measured weather data, not a climate model or a scenario-based forecast.
How certain is the temperature projection for Augusta?
The 2050 range runs from 13.2°C to 14.5°C. That spread comes from the 95% confidence interval on the trend line's own slope, so the noisier Augusta's record, the wider the band. The trend accounts for 30% of the variation between years; the rest is ordinary year-to-year swing.
How many days above 30°C will Augusta get in 2050?
The trend line lands on roughly 15 days above 30°C a year in 2050, against 17 in 2025. So no increase here, which means the warming in this city sits in the milder months rather than the summer peaks.
Will Augusta still get frost in 2050?
The trend line lands on roughly 136 frost days a year in 2050, against 139 in 2025. Fewer frost days sounds pleasant, but it also shortens the natural cold period plants and pest control rely on.
Is Augusta getting wetter or drier by 2050?
The trend line lands on roughly 1247mm of precipitation a year in 2050, against 965mm in 2025, so wetter. An annual total says little about distribution though: the same rainfall can arrive in shorter, harder bursts, and that is what loads drains and water storage.
Will Augusta get more sunshine by 2050?
The trend line lands on roughly 3006 sunshine hours a year in 2050, against 3083 in 2025, so less sun. Sunshine hours bear directly on rooftop solar yield, though heat works against it at the same time: a panel loses efficiency at high temperatures.
