What this means for the trip:
It rained on nearly every day, but the typical day saw only 3 to 4 hours of noticeable rain, and real downpour averaged 1.0 to 1.5 hours per day.
The rain is an afternoon and evening event. Only 0 to 5 percent of rainy hours fell in the morning window of 6 am to noon; the busiest hours were 4 pm to 8 pm both years.
Camp runs 8 am to 2 pm, which sat in the dry part of the day. The 2 pm walk home usually beats the 4 pm-and-later peak.
2024 was the wetter of the two (316 mm, 3 dry days) versus 2025 (220 mm, 7 dry days), so year to year varies.
