Method & Provenance
What “clear” means. A day qualifies when all three conditions hold: (1) average daily high ≥ 72°F, (2) total precipitation < 1 mm, (3) a non-precipitation WMO weather code. All three must be true. A warm, rain-free day with overcast skies does not qualify.
Data window. ERA5 reanalysis via Open-Meteo, 8 full years (2018–2025). “n” is the number of days sampled in each month across all 8 years; no month is below n=226.
Weather station substitution. Montage Palmetto Bluff is not one of the 55 long-term ERA5 almanac stations. The nearest station is Hilton Head, SC, approximately 15 miles away. All percentages in the table above are from Hilton Head, SC. This substitution is disclosed so a reader can verify it; the distance is small enough that the data is representative for seasonal planning.
Star rating. The 5-star rating for Montage Palmetto Bluff is provider-supplied from the RouteStack hotel API (measured 2026-08-07). It is a classification, not a review score. No aggregate rating or review count is shown because none was available in the source data.

Does Montage Palmetto Bluff have a hurricane season?
The Atlantic hurricane season runs June through November, peaking in August and September. The 8-year ERA5 historical data (2018–2025) includes all weather patterns across those years, hurricane-season effects included. The low clear-sky percentages in summer reflect this. We do not make predictions about specific hurricane risk for individual trips.
What is the price per night at Montage Palmetto Bluff?
No rate is shown here. Live pricing was not available in the source data at the time this page was built (nightly rate was absent from the RouteStack bulk search result). Showing a stale or estimated price would be misleading. Check the hotel directly or via a booking platform for current rates.
