7-Day Forecast

Weather by Season

Winter

Cold rain and occasional ice leave shaded roads and camps near Jasper soft or slick; reduced services and hunting activity require advance checks.

Spring

Repeated thunderstorms can saturate trails and raise rivers or reservoirs well after local rain ends around Angelina National Forest.

Summer

High humidity, mosquitoes and warm nights reduce recovery; tropical remnants may add falling limbs, flooded roads and poor water clarity near Jasper.

Fall

Early fall can remain tropical, while later dry spells raise fire danger and expose low-water access; hunting-season visibility matters around Angelina National Forest.

Key Climate Data Points

• Local climate: Large reservoir and forest conditions near Jasper make lake level the leading local planning signal.
• Annual mean temperature: Near Jasper, the annual mean temperature is generally in the mid to upper 60s °F; forest shade slows drying and moderates afternoon heat.
• Warmest or primary-use period: June through August is the hottest period; lake level often determines whether the primary activity remains practical.
• Coldest or limited-access period: December through February is coolest; snowfall is variable and generally brief, while ice, wind and shaded-road conditions cause the larger access impact.
• Most consequential precipitation period: Spring, with tropical rainfall possible through fall is the most consequential precipitation period here because it can affect lake level near Angelina National Forest.
• Primary hazard timing: Spring flooding, summer heat and late-summer tropical remnants most directly affects wind.
• Best general outdoor window: March through may and october through early december when trails are firm; the useful window still depends on lake level.
