About Lake Travis, Lake Austin & Hamilton Pool

Forecast guidance is centered on the principal visitor area near Lakeway. The wider reservoir, river and swimming preserve setting reaches toward Mansfield Dam, so local wind and access deserve a second check.

Plan Around Conditions

Compare the planned ramp with current lake elevation and LCRA flood operations; Hamilton Pool requires its own reservation and swimming status. Consult LCRA lake levels, flood operations and ramp notices, plus Hamilton Pool Preserve reservations before relying on conditional access.

Weather Tips

• Hamilton Pool Preserve uses reservations and may close swimming because of water quality, falling rock, flooding or other safety concerns.
• Turn toward the selected launch before thunderstorm outflow reaches open water; wind near Mansfield Dam can arrive ahead of rain.
• For heat, favor the portion near Lakeway with the shortest return and dependable shade or drinking-water plan.

Adjust the Day to the Forecast

7-Day Forecast

Weather by Season

Winter

Mild spells alternate with hard fronts near Lakeway; ice is uncommon but can close bridges, shaded limestone and elevated roads abruptly.

Spring

Peak flash-flood season can raise creeks and low-water crossings from upstream rain; lake elevation must be checked for the exact watershed around Mansfield Dam.

Summer

River and lake use depends on releases, spring flow, drought and bacteria notices as heat builds; popular access near Lakeway may also reach capacity.

Fall

Cooler weather expands hiking and camping time, but drought, burn bans and isolated flood-producing storms can change plans near Mansfield Dam.

Key Climate Data Points

• Local climate: Reservoir, river and swimming preserve conditions near Lakeway make lake elevation the leading local planning signal.
• Annual mean temperature: Near Lakeway, the annual mean temperature is generally in the mid to upper 60s °F; open terrain produces large sun-and-wind exposure.
• Warmest or primary-use period: June through August is the hottest period; lake elevation 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 and early fall is the most consequential precipitation period here because it can affect lake elevation near Mansfield Dam.
• Primary hazard timing: Spring severe storms, flash floods and summer heat most directly affects launch closures.
• Best general outdoor window: March through may and october through november when flood risk is low; the useful window still depends on lake elevation.
