In fair weather prepare for foul.

“In fair weather prepare for foul.” Thus spoke Thomas Fuller, the wise English divine and historian, whose words have endured like a lighthouse against the tempests of time. His counsel, though wrapped in the simple imagery of sky and storm, reveals a truth profound and eternal—that wisdom is not found in comfort, but in preparation; that the prudent heart readies itself in peace for the trials that must one day come. For fair weather never lasts forever, and those who build their strength only in the sunshine will be swept away when the dark clouds gather.

To prepare in fair weather is to understand the rhythm of life: that joy and sorrow, ease and hardship, prosperity and loss, follow one another as day follows night. The wise man does not curse the storm when it comes; he has already built his shelter. He has stored his provisions in the season of abundance, strengthened his foundations when the winds were still, and trained his spirit in patience while peace reigned around him. But the fool, lulled by comfort, believes that the gentle breeze will blow forever. He wastes his days in idleness, and when calamity descends, he cries out in despair—too late to act, too weak to stand.

Thomas Fuller, who lived through the turbulence of seventeenth-century England—a time of civil war, political chaos, and deep uncertainty—knew well the fickle nature of fortune. He saw kingdoms rise and fall, peace give way to bloodshed, and stability crumble into chaos. From such experience, he drew his wisdom: that a man’s safety lies not in the promise of peace, but in the prudence of foresight. His words are a reminder to every age that the world’s calmest moments are not an excuse for complacency, but an opportunity for preparation.

This truth has been proved again and again throughout history. Consider Sir Ernest Shackleton, the famed explorer who led his crew into the icy heart of Antarctica. Before setting sail, he trained his men relentlessly, prepared his ship for every imaginable peril, and stocked supplies far beyond what seemed necessary. When disaster struck—when their vessel, the Endurance, was crushed by the merciless ice—his foresight became their salvation. Though stranded in one of the harshest places on Earth, not a single life was lost. Shackleton’s preparation in “fair weather” saved them when the foul descended. His wisdom was the living echo of Fuller’s ancient truth.

To prepare for foul weather is not an act of fear, but of strength. The wise do not dwell in dread of misfortune; they simply refuse to be caught unready. They understand that life, like the sea, is ever changing—calm one day, raging the next. Thus, they train their minds in discipline, their hearts in courage, and their souls in faith. They save when fortune smiles, study when time allows, and build character when comfort tempts them to rest. In doing so, they become as the oak that endures the storm while lesser trees are uprooted.

And yet, this wisdom applies not only to the storms of circumstance, but to the tempests within the soul. For there are times when the fair weather of joy blinds us to the gathering clouds of pride, laziness, or self-deceit. The wise heart keeps watch even then, fortifying itself with humility, gratitude, and discipline. It is in peace that one must learn patience; in strength that one must learn mercy; in victory that one must learn humility. Those who prepare their hearts thus are never defeated, no matter how fierce the storm may rage.

Therefore, O seeker of understanding, take this counsel to heart: when life is calm, do not sleep; when fortune smiles, do not waste. Use the brightness of your present to build strength for the shadowed days to come. Save what you can, learn what you must, and nurture the friendships and virtues that will sustain you when the winds turn cold. For life will surely test you—and only those who have prepared in fair weather will stand firm when the skies grow dark.

The lesson is clear: do not mistake peace for permanence. The calm seas of today may give way to the storms of tomorrow, but those who prepare need not fear. Be watchful, be diligent, and live with foresight, for as Thomas Fuller taught, “In fair weather prepare for foul.” It is the mark of the wise to greet the sun with gratitude—but to keep their hearts ready for the rain.
