Last week I mentioned how common showers are at this time of year, and that it’s not unusual to have a “chance of rain” (or a supposed “certainty of rain”) -- often announced in the most negative way -- in many weekend forecasts.
Several years ago I wrote out a list of “Rain & Weather Forecast Basics” (or “Charlie’s Rain Rules”) for a weekly Update, and I’m re-running it again below, since not everyone is especially well-informed on the subject.
As I often mention, many weeks I hear from people who say “It’s going to rain” or “We’re going to have bad (or beautiful) weather” several days beforehand, and who make plans based on long-range forecasts, which they trust (mistake!)
It’s clear to anyone who pays close attention that short and long-range forecasts often change (and keep changing) from one day to the next, and the weather we get on a weekend may or may not bear any resemblance to what was predicted.
Please read and consider the following carefully, especially if you’re new or relatively new to hiking. Experienced hikers may want to peruse it as a review, and keep it in mind whenever you hear a forecast for a rainy day or weekend:
1. The accuracy of weather forecasts for the mountain areas where we hike tends to be quite low, especially in the higher mountains, which sometimes generate their own weather systems that are inherently unpredictable.
2. It’s not uncommon for the weather we encounter on a trip to be totally different or even the opposite of what was predicted. On some days when rain is in the forecast we find ourselves hiking in dry or even sunny weather, whereas sometimes on days with “zero chance of rain” we get caught in a shower or two.
3. The relevance of a New York City, Hudson Valley, or other “low-elevation” forecast to any of the mountain areas we visit is especially limited.
4. It’s wise to ALWAYS assume the possibility of rain in the mountains, regardless of the forecast.
5. It’s sensible to assume as well that sunshine or dry weather are ALWAYS possible in the mountains, regardless of the forecast.
6. In other words: be prepared for ALL possible weather on all hikes (and ALWAYS bring rainwear and warm clothing along, just in case).
7. It’s best to keep your weather expectations to a minimum and be prepared to enjoy the day whatever the weather (it’s a waste of time and energy to be fretting about a “negative forecast,” or to be overly celebratory about a “positive forecast”).
8. It’s a major error to assume that what’s happening outside your window early the morning of a hike, weather-wise, has anything at all to do with what it will be like in the area where we’ll be hiking (some hikers stay home when it’s raining early in the morning, and miss out on what often turns out to be a fair-weather hike).
9. On probably an average of three out of four days when rain is in the forecast we get no more than 15 minutes or so of rain during the hike, and sometimes none at all.
10. On probably one out of four days when rain is in the forecast we DO get significant rain.
11. On an average of an estimated 1-3 hikes per year (out of a total of 80-90 that we offer annually) we actually find ourselves hiking in “major rain,” meaning heavy rain for more than a few minutes, or nearly continuous light rain. (If there’s a strong likelihood of continuous heavy rain and/or other severe weather, a trip may be cancelled).
12. Many people aren’t aware (and weather forecasters rarely tell us) that heavy rain in the mountains -- on the relatively infrequent occasions when it does come -- tends to fall early or late in the day. Often it’s over by the time we start a hike, or arrives after we’re done (and very often on “rainy days” it stops for several hours from mid-morning till mid-afternoon).
13. While short-term forecasts are frequently wrong, long-range forecasts tend to be so inaccurate that they’re almost meaningless, especially for the mountain areas. To make a decision several days or a week in advance about whether to hike, based solely on a 5-day or 7-day forecast, isn’t a rational thing to do.
14. The tone of certitude (and absence of humility or acknowledgement of the degree of uncertainty) that comes with many forecasts is inappropriate and misleading.
15. It’s no secret that exaggerations, distortions, and sensationalism have crept into weather forecasting over the years, just as they have come to infuse much mainstream commercial news in general. There’s a tendency to refer to a bit of rain or a chance of showers as “nasty,” “horrible,” “awful,” “dismal,” or simply “bad” weather. And even when there’s just a small chance of precipitation, or when it’s likely to come during evening or nighttime hours and thus have no effect on outdoor recreation, the weather headlines will still often be “rainy weekend ahead.”
16. Lack of appreciation of the importance of rain is rampant in our society and our media. Everyone should be aware that rain is a vital part of the life cycle and absolutely essential to our well-being and even survival (if the rain ceased it would be catastrophic and fatal for most life forms, and would mean an eventual end to cities and much of civilization – and to us! -- since in time all fresh water would disappear and most human beings would be unable to meet their water needs).
17. Being out in the rain won’t and can’t spoil your day unless you let it! In fact, as many hikers know and frequently comment on, during the warmer seasons (when flowers are blooming and vegetation is lush) the natural world can be lovely in the rain, and communing with nature at such times can be a memorable experience, believe it or not -- assuming you have appropriate raingear, sufficient clothing, and the right attitude. On a warm summer day, rain or showers can be delightfully refreshing. In cooler temperatures rain may initially seem more intimidating to those who haven’t been fully initiated into “the pleasures of wet weather,” but when you’re properly dressed, walking in the rain can be an invigorating, sense-stimulating, enlivening, and at the same time soothing and peacefully relaxing experience. Be open to the possibility of actually learning to enjoy it!
