Jacksonville, Illinois
Weekend air in Jacksonville sits near 83°F / 61°F, plus only light rain on the books (~0.13 in) — enough to decide whether the trip is on.
What matters isn’t whether Jacksonville is famous — it’s whether 2026-08-22 – 2026-08-29 supports the outdoor time you want (heat-seeking highs).
If the numbers still look good by Friday, lock the plan around 83°F — not a vague “nice weather somewhere.”
